I have a carton cpanfile. on servers on which I have sudo, I would be happy to install the latest versions of my modules globally instead.
do I write a script that removes the 'requires' and uses cpan -i (although I am concerned that I may have too many to fit the command line limit), or is this functionality already somewhere else?
If there is a cpanfile you can just run
$ cpanm --installdeps .
as root (with sudo) in the directory with the cpanfile and cpanm will read it and install your dependencies to whatever Perl is configured for this cpanm.
You can ignore carton for that completely.

I use perlbrew to easy switch between perl.
I use Carton to install modules only for current project into /local directory.
But when I deploy application on new host.
I do:
perlbrew install -v -j 8 --notest --switch perl-5.30.3
perlbrew install-cpanm
cpanm Carton
But last step will install Carton into perlbrew libs
Is there a way to install Carton into my project local/lib/perl5 directory?
I want to keep base perlbrew clean
To install modules into your own directory we can use --local-lib option.
It is mentioned here and described at examples cpanm --help
cpanm --local-lib ./local
probably useful options for this task are:
-n,--notest Do not run unit tests
--self-contained Install all non-core modules, even if they're already installed
If you do deploy often probably you do not need to retest each time. This is meaningless.
Second option is useful when you want modules to be installed into you local directory despite on they are already installed into system/brew perl
I downloaded the source to Perl and compiled/installed into a shared directory for my team. By default, Perl doesn't include XML::DOM and I need to add it to the installation. How do I do this?
I tried cpan and it installs to ~/perl5 by default. I tried cpanm next (cpanm -l $install_path XML::DOM) but perl still can't find it in #INC. I'm using perl 5.32.0.
You have env var telling the module's installer to install it in an undesired place.
Unset the following env vars:
PERL_MM_OPT
PERL_MB_OPT
Don't call any cpan or cpanm, call cpan with your perl or inspect which perl is called with your tool by looking at the header.
/path/to/my/perl -S cpan XML::DOM
I have found it necessary to expand upon a CPAN module. (Unicode::CharName goes up to Unicode 4.1; I need some characters from Unicode 5.0 & 5.1).
I've made the changes needed and have my own CharName.pm module.
I now would like to use it with my various Perls. I currently use:
Strawberry Perl for Windows
git for Windows MINGW64; My .bashrc sets
$PATH to Strawberry perl and $PERL5LIB=/c/Strawberry/perl/vendor/lib:/c/Strawberry/perl/site/lib
WSL Ubuntu
Where should I put my version of Unicode::CharName, so that it over-rides the ones installed by CPAN?
I don't want to have to change any scripts that currently
use Unicode::CharName;
Using cpanm you could download the module, patch it, and install it as normal:
$ cpanm --look Unicode::CharName
# new shell opens
$ patch lib/Unicode/CharName.pm custom.patch # or whatever process
$ perl Makefile.PL
$ make install
$ exit
You can also install it to a local::lib to avoid overwriting it globally, by adding the -l local/ option to the cpanm command. Then you can add the absolute path of this local::lib to your PERL5LIB or via -I or use lib. If you specified /path/to/local for the -l option, it would be /path/to/local/lib/perl5.
Manually copying files rather than going through the normal installation process is likely to lead to problems. Many distributions depend on the installation process to build the modules correctly. Also, you will need to install the module separately for each Perl you want to use it for; installed Perl modules are not generally cross-compatible between Perl versions or architectures. (A strictly simple pure-Perl module can be an exception to these rules, but the only module I feel comfortable abusing this way is App::cpanminus, because it was designed to do this.)
I am on a Linux machine where I have no root privileges. I want to install some packages through CPAN into my home directory so that when I run Perl, it will be able to see it.
I ran cpan, which asked for some coniguration options. It asked for some directory, which it suggested ~/perl "for non-root users". Still, when I try to install a package, it fails at the make install step, because I don't have write access to /usr/lib/perl5/whatever.
How can I configure CPAN so that I can install packages into my home directory?
See local::lib.
Once you have it installed, you can do:
perl -MCPAN -Mlocal::lib -e 'CPAN::install(LWP)'
There's the way documented in perlfaq8, which is what local::lib is doing for you.
It's also a frequently asked StackOverflow question:
Why does installing certain CPAN modules require root privilege?
How can I install CPAN modules locally without root access (DynaLoader.pm line 229 error)?
How do I tell CPAN.pm to install all modules in a specific directory?
How can I install a CPAN module into a local directory?
How can I use a new Perl module without install permissions?
How can I use CPAN as a non-root user?
How can I install local modules with the cpan tool?
Curiously, none of these are suggested when I use your original question title (which is one of the reasons a good title is very important in finding your answer).
How do I keep my own module/library directory?
When you build modules, tell Perl where to install the modules.
If you want to install modules for your own use, the easiest way might be local::lib, which you can download from CPAN. It sets various installation settings for you, and uses those same settings within your programs.
If you want more flexibility, you need to configure your CPAN client for your particular situation.
For Makefile.PL-based distributions, use the INSTALL_BASE option when generating Makefiles:
perl Makefile.PL INSTALL_BASE=/mydir/perl
You can set this in your CPAN.pm configuration so modules automatically install in your private library directory when you use the CPAN.pm shell:
% cpan
cpan> o conf makepl_arg INSTALL_BASE=/mydir/perl
cpan> o conf commit
For Build.PL-based distributions, use the --install_base option:
perl Build.PL --install_base /mydir/perl
You can configure CPAN.pm to automatically use this option too:
% cpan
cpan> o conf mbuild_arg "--install_base /mydir/perl"
cpan> o conf commit
INSTALL_BASE tells these tools to put your modules into /mydir/perl/lib/perl5. See How do I add a directory to my include path (#INC) at runtime? for details on how to run your newly installed modules.
There is one caveat with INSTALL_BASE, though, since it acts differently than the PREFIX and LIB settings that older versions of ExtUtils::MakeMaker advocated. INSTALL_BASE does not support installing modules for multiple versions of Perl or different architectures under the same directory. You should consider if you really want that, and if you do, use the older PREFIX and LIB settings. See the ExtUtils::Makemaker documentation for more details.
CPAN way
run cpan command. If you don't have CPAN configurated, do it first! Otherwise, you will see the cpan prompt. In this case, type look local::lib and you will have a new shell prompt. In this new shell, run the bootstrap command configuring and compiling the module at same time as at bellow.
user#host:~/.cpan/build/local-lib-1.004003-UyX2wf$ perl Makefile.PL --bootstrap && make test && make install
Now, export some variables:
Path where local::lib will install things
echo 'eval $(perl -I$index.t/perl5/lib/perl5 -Mlocal::lib)' >> ~/.bashrc
And Perl variable to avoid user input
echo 'export PERL_MM_USE_DEFAULT=1' >> ~/.bashrc
Now load your bashrc running
source ~/.bashrc
Try to install running cpan <SOME_VALID_MODULE_NAMESPACE>
That's it! Now you can install modules using cpan without root privileges. But, remember that this will work just for the CURRENT USER including the root user !
cpanminus way
If you have this installed your sys admin deserves a beer!
Just run
$ cpanm --local-lib=~/perl5 local::lib && eval $(perl -I ~/perl5/lib/perl5/ -Mlocal::lib)
Open another terminal and run
$ env |grep PERL
You should see something like this:
PERL5LIB=$HOME/perl5/lib/perl5 PERL_MB_OPT=--install_base "$HOME/perl5"
PERL_LOCAL_LIB_ROOT=$HOME/perl5
PERL_MM_OPT=INSTALL_BASE=$HOME/perl5
But if you're not, export variables like this:
$ echo "export PERL5LIB=\"$HOME/perl5/lib/perl5\"">>~/.bashrc && \
echo "export PERL_MB_OPT=\"--install_base '$HOME/perl5'\">>~/.bashrc && \
echo "export PERL_LOCAL_LIB_ROOT=$HOME/perl5">>~/.bashrc
Finally, load your bashrc file and try to install with commands
source ~/.bashrc
and
cpanm <SOME_VALID_MODULE_NAMESPACE>
Fim!
Here is my situation: I know almost nothing about Perl but it is the only language available on a porting machine. I only have permissions to write in my local work area and not the Perl install location. I need to use the Parallel::ForkManager Perl module from CPAN
How do I use this Parallel::ForkManager without doing a central install? Is there an environment variable that I can set so it is located?
Thanks

From perlfaq8: How do I keep my own module/library directory?:
When you build modules, tell Perl where to install the modules.
For C-based distributions, use the INSTALL_BASE option
when generating Makefiles:
perl Makefile.PL INSTALL_BASE=/mydir/perl
You can set this in your CPAN.pm configuration so modules automatically install
in your private library directory when you use the CPAN.pm shell:
% cpan
cpan> o conf makepl_arg INSTALL_BASE=/mydir/perl
cpan> o conf commit
For C-based distributions, use the --install_base option:
perl Build.PL --install_base /mydir/perl
You can configure CPAN.pm to automatically use this option too:
% cpan
cpan> o conf mbuild_arg --install_base /mydir/perl
cpan> o conf commit
INSTALL_BASE tells these tools to put your modules into
F. See L for details on how to run your newly
installed moudles.
There is one caveat with INSTALL_BASE, though, since it acts
differently than the PREFIX and LIB settings that older versions of
ExtUtils::MakeMaker advocated. INSTALL_BASE does not support
installing modules for multiple versions of Perl or different
architectures under the same directory. You should consider if you
really want that , and if you do, use the older PREFIX and LIB
settings. See the ExtUtils::Makemaker documentation for more details.
Download package form CPAN to a folder:
wget http://search.cpan.org/CPAN/authors/id/S/SZ/SZABGAB/Parallel-ForkManager-1.06.tar.gz
gunzip Parallel-ForkManager-1.06.tar.gz
tar -xvf Parallel-ForkManager-1.06.tar
before this create a folder in home to store your local modules, now go into downloaded folder and run follwing cmmands:
perl Makefile.PL PREFIX=/home/username/myModules
make
make test
make install
get the path to ForkManager from the installed folder,/home/username/myModules
and locate Parallel folder and get the full path to this.
Now in your perl file put these at the beggining
use lib '/home/username/myModules/bin.../Parallel';
use parallel::ForkManager;
--That should do it.
Check out this post from Mark Dominus
Excerpt:
Set PREFIX=X when building the Makefile
Set INSTALLDIRS=vendor and VENDORPREFIX=X when building the Makefile
Or maybe instead of VENDORPREFIX you need to set INSTALLVENDORLIB or something
Or maybe instead of setting them while building the Makefile you need to set them while running the make install target
Set LIB=X/lib when building the Makefile
Use PAR
Use local::lib
Mark also gives another solution in his blog which takes a bit more space to desribe but boils down to running make and make test but not make install and then using the stuff in blib/.
There's the PERL5LIB environment variable, and -I on the command line when it comes to using the module. There are mechanisms for telling CPAN and CPANPLUS.
There is information in question 5 of the CPAN manual (perldoc CPAN, or look at CPAN itself).
use lib 'directory';
use Parallel::ForkManager;
You can use the -I (capital i) command-line switch followed by the directory where you'll place the module; or try the "use lib" directive followed by the directory.
Yes Even You Can Use CPAN
perl Makefile.PL LIB=/my/perl_modules/lib/
make
make install
PERL5LIB=$PERL5LIB:/my/perl_modules/lib/
perl myperlcode.pl
use cpanm -l $DIR_NAME option.
perlbrew lets you use a local perl and installs it's packages to a local directory.
\curl -L https://install.perlbrew.pl | bash
perlbrew init # put this in .bash_profile etc
perlbrew install 5.27.11
perlbrew switch 5.27.11
