I am attempting to install a Perl Module entitled: File-Copy-Recursive and I am following these steps:
1) open cmd.exe
2) perl -MCPAN -e 'install File::Copy::Recursive;'
and I receive the message "It looks like you don't have a C compiler and make utility installed. Trying to install dmake and the MinGW gcc compiler using the Perl Package Manager. This may take a few minutes..."
"Downloading ActiveState Package Repository packlist...failed 500 Can't connect to ppm4.activestate.com:80 (connect: timeout).
Downloading File-Copy-Recursive packlist...not found
ppm.bat install failed: Can't find any package that provides MinGW"
These failed because I am behind a proxy, and I do know the proxy settings but I don't know how to apply them in this situation.
Is anyone aware of any alternative fixes to this solution?
Thank you.
It seems you are using ActiveState Perl, which comes with its own package manager (called PPM) to ease the pain of installing modules, especially those which would normally require a C compiler to be able to install.
Try following the instructions to set up your environment so that PPM knows about your proxy. For example, to set the proxy settings for a single instance of cmd.exe:
C:\>set http_proxy=http://username:password#proxy.example.org:8080
Then, in the same command prompt window, try this (it works for me, though I'm not behind a proxy):
C:\>ppm install File-Copy-Recursive
Note that it's probably a good idea (maybe even required?) to run cmd.exe "As Administrator" to make sure it has full authorization.
EDIT: The particular module you want to use is written in pure Perl. For a quick "installation", you can just download it from CPAN, extract the files, and copy the "Recursive.pm" file into a File\Copy directory structure placed in the same directory as your script:
yourscript.pl
File\
Copy\
Recursive.pm
As an alternative you could try the Strawberry Perl distribution which comes with tools for building XS modules.
Hi
I guess you are using Activestate Perl
look at
http://docs.activestate.com/activeperl/5.10/faq/ActivePerl-faq2.html#what_is_ppm
PPM is installed automatically with ActivePerl.
To use PPM, your computer must be connected to the internet, have access to a PPM repository on a local hard drive or network share, or have access to a mounted ActiveState ActiveDVD.
If you connect to the internet via firewall or proxy, you may need to set the http_proxy environment variable. See PPM, Proxies and Firewalls for more information.

I trying to get set up with Variant Effect Predictor (VEP) on the command line. I'm following the setup tutorial but I'm encountering some errors around dependencies. I'm also quite new to the command line so if anyone is able to break down the solution too then I'd be very grateful. Thanks!
Tutorial: https://www.ensembl.org/info/docs/tools/vep/script/vep_tutorial.html
VEP requirements: http://www.ensembl.org/info/docs/tools/vep/script/vep_download.html#requirements
I also have Perl v5.32.1.
What I've done:
I installed dependencies (listed in the requirements page) with the following commands:
- sudo -s cpanm DBI
- sudo -s cpanm Archive::Zip
- sudo -s cpanm DBD::mysql
For DBD:mysql, I got the follwoing message:
--> Working on DBD::mysql
Fetching http://www.cpan.org/authors/id/D/DV/DVEEDEN/DBD-mysql-4.050.tar.gz ... OK

! Configure failed for DBD-mysql-4.050. See /root/.cpanm/work/1626111140.5937/build.log for details.
Trying it out anyway, I ran perl INSTALL.pl (from the tutorial page) and got the message below. I would like VEP to run in online mode too if possible.

You show us this error:

So looking in there will give you more clues about what the problems are. Without that, we can only guess.
But we can make educated guesses. The DBD::mysql distribution comes with a file called DBD::mysql::INSTALL which will talk you through some of the problems you'll find while installing this module.
It's important to note that DBD::mysql is a wrapper around MySQL's client libraries. They are written in C, so you'll need a C compiler installed in order to build DBD::mysql. You'll also need the client libraries and the development versions of the client libraries (for the C header files that you'll need to compile the module). On Ubuntu, those packages are called "libmysqlclient" and "libmysqlclient-dev". If you don't have a C compiler, then you'll want to install "gcc" too.
But this is all getting a bit complicated. There's another, simpler, approach. If you're using the system version of Perl (the version that was installed as part of the operating system and probably lives in /usr/bin/perl) then I'd recommend using the pre-build Ubuntu version of the package, which you can install by running:
$ sudo apt-get install libdbd-mysql-perl
Installing that version uses the OS's own package manager, and the package manager knows which other packages are needed in order for it to work - so it will install those as well.
People will probably complain that you're better off installing the modules from CPAN as it gives you more flexibility and allows you to use more up-to-date packages than the versions from your OS repos. And they're right. But, honestly, if you're a non-Perl programmer who just wants to get an application up and running, this is by far the simplest approach.
(But, as I said above, this is all guesswork as you haven't shared the most important errors with us.)
Because i have a long series of comments with #ikegami, I cleaning up the question, in a hope it will be more understandable. Unfortunately, english isn't my "main" language. :(
Let say, having an environment where:
no development tools are installed (no make, nor gcc or like)
perl is installed with its core packages, nothing more
no outgoing network access is allowed - e.g. the user couldn't use curl nor cpan to download/install perl dependencies
the user even doesn't have admin (root) rights
but want install and evaluate some perl based web-app, let call it as MyApp
The MyApp
doesn't uses any XS-based module. (at least, I hope - in the development me using plenv and cpanm, so never checked the installed dependencies in depth)
it is an pure PSGI app, the simple plackup app.psgi works OK
the app uses some data-files which should be included in the "deployment".
The main question is: how to prepare the MyApp, and the all used CPAN-modules, to be easily installed in such restricted environment?
The goal is:
i don't need save my efforts and my time
but i want save the user's time and want minimize the needed actions on his side, so the installation (deployment) should be simple-as-possible.
E.g. how to get an running web-app to the user's machine with minimum possible (his) steps.
- the simplest thing is could be something as:
- copy one file (zip, or tarbal)
- unpack it
- from the terminal execute some run.pl in the unpacked directory.
To get the above simple installation, my idea was the following:
1.) Create an tarball, and after the unpacking will contain 3 folders and 1 perl-script, let say:
myapp_repo/
myapp_repo/distlib #will contain all MyApp's perl modules also ALL used CPAN modules and their dependecies
myapp_repo/datafiles #will contain app-specific data files and such
myapp_repo/install.pl
myall_repo/lib #will contain modules directly used by the `install.pl`
2.) I will develop an install.pl script, and it will be used as the installer-tool, like
perl install.pl new /path/to/app_root
and it will (should):
create the all needed directories under the /path/to/app_root (especially the lib where the will install the perl modules)
will call "local" cpanm internally (from the myapp_repo/lib) to install the app's perl modules and their CPAN dependencies using only distribution files from the distlib.
will generate and install the needed runtime script and the app.psgi into the /path/to/app_root/bin
will install the needed data-files for the app.
3.) So, after this the user should be able to simply run:
/path/to/app_root/bin/plackup /path/to/app_root/bin/app.psgi
In short, the user should use:
the system-wide perl and the system-wide perl-core modules
and any other
runtime perl-scripts (like plackup)
and the required CPAN-modules
should be installed to an self-contained directory tree using only files (no net-access).
E.g. the install.pl should somewhat call internally the cpanm to achieve (as equivalent) for the following cpanm command
cpanm --mirror file://path/to/myapp_repo/distlib --mirror-only My::App
which, should install My::App and all dependencies without network access using only the files from the myapp_repo/distlib
Some questions:
Is possible to use cpanm (called as an locally installed module) without the make?
For creating the myapp_repo/distlib, me thinking about using Pinto. Is it the right tool for achieve the above?
forgot me something? or with other words:
Is the above an viable (read: working) way?
are are any other tools, which i could/should to use for simplifying the creation of such distribution tarball?
#ikegami suggesting some method:
- "install everything" in one fresh-directory on my machine
- transfer this self-contained directory to the target machine
It sound very good, because this directory could contain all the needed app-specific data-files too, unfortunately, I don't understand the details how his solution should be done.
The FatPacked solution looks interesting too - need learn about it.
Don't write your own make or installer. Just copy it make from a different machine (which is basically what apt/yum/etc do anyway, and which you'd have to do even if you wrote your own). You'd be able to use cpan in 5 minutes!
Also, that should allow you to install gcc if you need it (e.g. to install an XS module), although it doesn't sound like you do. If you do install gcc, I'd install my own perl to avoid having to deal with PERL5LIB.
Tools such as minicpan will allow you to install any module from CPAN without internet access. Of course, you can keep using the command you are already using it if mirrors the packages you need.
The above explains how to simply and quickly setup a machine so it can use cpan and thus install any module easily.
If you just want to install a specific module and its dependencies, you can completely avoid using cpan on the target machine. First, you need a fresh install of Perl (preferable of the same version as the one on the target system). Then, simply install the module to a fresh dir on your machine, and transfer that dir to the target machine. That's it; nothing else needs to be done. This even works for XS modules if the two machine are similar enough.
This is what ppm (ActiveState's Perl package manager) does.
Unfortunately, while this solution is almost as simple as the one above, it's not nearly as flexible, it doesn't run the test suite of the modules being installed, etc. It does have the advantage of not requiring the transfer of any binary (if you're not installing any XS modules).
I've already read related threads like these, but they do not fully capture our situation.
This is on a firewalled machine. No net access. We can ftp files to folders and install modules from there.
We have CHMOD 777 for our users on some folders. We can install Perl modules if we locally build them by downloading the relevant .pm files. But when these files cannot install, we do not have any cpan or cpanm.
I'd like to install, for example, HTML::Restrict. If I do the download + install thing, the Restrict.pm gives me this error:
/lib/HTML/Restrict.PM:328: Unknown command paragraph "=encoding UTF-8"
Reading a bit online suggests that this could be an old Perl problem. We use 5.8.x. Our own dev machines have the luxury of 5.16.x and internet access so installing module is a cinch. Anyway, one of my older machines also has 5.8.x, and installing the module via cpanminus worked there (with internet).
So, question: is it possible to install "cpanminus" (cpanm) through FTP, then upload specific module files to the server through FTP too, and then go into shell and install modules via cpanm by pointing it to respective .pm files?
Thank you for any pointers.
You should take a look at perldoc perlmodinstall which goes into detail about how to install a module from its distribution. It follows what should be a familiar incantation
Decompress
Unpack
Build
Test
Install
Assuming you're on a Linux system, this commonly takes take the form of
gzip -d My-Module-Distribution.tar.gz
tar -xof My-Module-Distribution.tar
perl Makefile.PL
make
make test
make install
But after the Unpack stage you will often find a README file or other text file that will describe any unusual steps to be taken
Clearly some of these steps can be combined. For instance, most people will probably want to use
tar -xvfz My-Module-Distribution.tar.gz
to avoid having to invoke gzip separately. Likewise, the make system will force a build phase as a prerequisite if you use just
make test
without the preceding make
The linked document has a lot to say about how to install on other platforms, should you not be running a Linux variant
I still don't really understand your thinking, but you can get a stand-alone version of cpanm using curl. For instance
curl -sS --location https://cpanmin.us/ --output cpanm
then you should be able to just copy it to your target machine, put it on your PATH, and do
cpanm HTML-Restrict-2.2.2.tar.gz
but I doubt if you will find any change to the specific errors you are getting
I'm running Windows 7 64 bit, which seems to be part of the problem. At first my cpan would hang when I would try to install CPAN from the shell prompt.
I tried restarting my computer, and a variety of attempts to use rebaseall and peflagsall from ash- even starting a new base for the dll's (the command was something suggested on a cygwin mailing list- something like rebaseall -vb 0x730000).
Should I just uninstall Cygwin and try to do a total reinstall? I have all the dependencies that cpan should need (i.e. gcc-4).
I'm getting pretty desperate here- I'm getting error messages that talk about failed dlls if I try to use modules installed from CPAN (specifically, JSON::XS).
Any help you could offer would be fantastic.
Thanks!
The complaining about missing dlls when installing is a known bug I believe, and appears for a lot of modules. Most modules are still installed and still work however. In my experience, you need to force install most modules as well, as there is almost always some test that fails.
While I personally prefer perl from the cygwin environment, there is one good reason for installing Strawberryperl; the need for 64 bit support which cygwin does not support. If you are going to work with large XML data structures using XML::Simple for instance, the 1.5-2GB that 32-bit Windows support will not take you far, and Strawberryperl will come to your rescue. And thanks to perl portability, and apart from keeping two sets of perl's installed on the same computer, the is no problem doing development using cygwin, and then running it "in production" using 64-bit Strawberryperl.
Are you installing cygwin and then building Perl on top of that? You will be far more successful if you use Strawberry Perl which comes with its own cygwin environment that will allow you to build and install most CPAN modules if you need them
I suspect the problem you're hitting is the difference between the regular shell (which will normally be bash and give you a $ prompt on Cygwin) and the cpan shell (which will give you a prompt like cpan[1]>).
In the cpan shell, install CPAN will refresh a bunch of Perl scripts from the CPAN repository. From a bash shell, install CPAN just doesn't make sense: install is a program for installing packages you've just built; it has nothing in particular to do with Perl or with how you install packages on Cygwin.
You can enter the CPAN shell by running cpan at bash shell prompt. But I don't think that's what you need. What you actually want to do is just run the following:
cpan JSON::XS
I want to send emails using gmail's smtp servers and perl. I am trying to install Email::Send::Gmail, but it is not clear to me what are the steps to install it. It seems that it depends on other modules that I do not have installed.
This is partially dependent on which distribution of Perl you're using.
ActivePerl includes a utility called PPM (Perl Package Manager) for installing modules. It handles dependency resolution automatically. PPM is particularly nice for installing XS modules on Windows where a compiler isn't typically available. The downside to PPM is that it some CPAN modules aren't available (probably because they fail ActiveState's automated build process). You can run PPM from either the start menu or by typing ppm at a command prompt.
A more general option is to use the interactive CPAN shell. Note that you must have a compiler to install XS modules using this method. You can access the cpan shell by typing cpan at a command prompt.
The brute-force approach of last resort is to download tarballs from CPAN and manually install them one at a time. When an install aborts due to unsatisfied dependencies download and install them then go back to the first module and try again.
Type:
cpan Email::Send::Gmail
… at the command prompt.
It's probably a good idea to set up local::lib first.
Or see the Perl Foundation Wiki on installing CPAN modules or the same but without root access.
Or see the CPAN guide to installing modules.
If you are using ActivePerl, try the PPM (Perl Package Manager) tool that comes with ActivePerl first. When you tell it to install a module, it should handle all of the dependencies for you.
Note the dependency tree for Email::Send::Gmail. Some of those modules require additional installation of third party software, most notably OpenSSL, which cpan won't do for you.
You can probably install it with:
perl -MCPAN -e shell
install Email-Send-Gmail
Hope it helps,

If you can, CPAN. (ha! It rhymes ... what a crime. Oops, did it again! When will this end... :p) It's essentially the way to install modules for your system. It automatically detects dependencies, downloads, installs, and tests them all for you, and backs out if ever a build or test fails. It's a fantastic and reliable way of installing modules. This works great if you're using essentially any Perl distribution besides ActiveState's distribution, including Strawberry Perl. Generally, this is done with
cpan Module::Name
or, in an interactive mode,
$ cpan
cpan > install Module::Name
If you're using ActiveState Perl, then you probably want to use ActiveState's PPM (Perl Package Manager). It's similar to CPAN, except everything comes prebuilt for ActiveState Perl. ActiveState has a document on how to use their Perl Package Manager on their website, including a graphical example.
If the easy options fail, you are not out of luck. There's some more complex, but manual methods you can do to still install the module.
Most modules that you can download will have within them a bit of metadata in a .yaml file; this will help you figure out whether or not you have all your dependencies. CPAN and PPM automatically resolve and install all your dependencies, but doing it manually will not, leaving that task up to you.
Assuming you have all your dependencies, and you need to install it manually, look for one of two files: Makefile.PL or Build.PL. If you have a Makefile.PL, cd to the directory you extraced the module within a command prompt, and type:
perl Makefile.PL
make
make test
make install
You will need a 'make' program on your system. If it's ActiveState Perl, you may need to install the module manually (see a paragraph or two down.)
If it happens to have a Build.PL, then you need to do a slightly different set of steps:
perl Build.PL
Build
Build test
Build install
(Of course, you may want to consider not installing if make/Build test fails, but that's up to you.)
As a final alternative, if your module has no xs files (ie, code that needs to be compiled on install), and all dependencies are met, you can simply move the files in the lib folder to your perl installation's site\lib folder. If you're interested in just using it for one project, you can add a PERL5LIB environmental variable, pointing to a new, custom library directory (eg, /my/project/lib) and then before running your tool, make sure the environment is set up.
As a followup, see PerlFaq8 - How do I install a module from CPAN.
Also, see PerlFaq8 - How do I keep my own module/library directory?.
Mixing installation methods is asking for heartache and headaches you don't need.
Don't use CPAN with Active Perl. Use PPM.*
PPM download sources can be found at Randy Kobes' site.
If you can't find a PPM of a module you need, you can build your own PPMs easily with Mr. Kobes make_ppm.
You can download a distribution and simply run make_ppm to build a PPM, but I prefer to do the a more "normal" build process:
perl Makefile.PL
make
make test
make_ppm
*If you install your files outside of c:/perl/site/* then it's OK to use CPAN. Just don't co-mingle CPAN shell modules with PPM modules.
