I have a script on Windows which uses multiple pure Perl modules from CPAN.
I am trying to ship this script without the need to reinstall those modules from CPAN using App::FatPacker.
I installed App::FatPacker ( up to date (0.010007) version ) on Portable Strawberry Perl 5.24 .
When I run the following command
fatpack pack myscript.pl > myscript.packed.pl
I get
syntax OK
but the fatlib is empty and when I run my script it fails.
I tried to use this script which does nothing but load Geo::IP::PurePerl
use strict;
use warnings;
use Geo::IP::PurePerl;
and run again this command :
fatpack pack myscript.pl > myscript.packed.pl
Then I ran myscript.packed.pl on another instance of Strawberry Perl 5.24, I get the following error:
Can't locate Geo/IP/PurePerl.pm in #INC (you may need to install the Geo::IP::PurePerl module
I tried to debug it by building step by step
The fatpack trace creates a trace list as expected, including Geo::IP::PurePerl
The fatpack packlists-for finished successfully but the fatlib is empty.
Any idea?
I would say that packlists-for isn't finding any .packlist files
The documentation for fatpack says this
packlists-for
$ fatpack packlists-for Module1 Module2 Module3
Searches your perl's #INC for .packlist files containing the .pm files for the modules requested and emits a list of unique packlist files to STDOUT.
These packlists will, in a pure cpan-installation environment, be all non-core distributions required for those modules.
Unfortunately most vendors strip the .packlist files so if you installed modules via e.g. apt-get you may be missing those modules; installing your dependencies into a local::lib first is the preferred workaround.
I think that's useful advice that may well fix your problem

I have a perl program that uses WWW::Mechanize::Firefox on windows 7 32bit with strawberry perl.
It works fine with the command C:\>perl testcase.pl. When I compile it with C:\>pp -o testcase.exe testcase.pl it compiles with no errors.
When I run the testcase.exe it gives me the error:
Failed to connect to , Can't locate object method "setup" via package "MozRepl::Client" at MozRepl.pm line 224
The code I am using for testcase.pl is:
#!perl
use MozRepl;
use WWW::Mechanize::Firefox;
use warnings;
system('start firefox');
sleep(5);
$mech = WWW::Mechanize::Firefox->new;
Also note that a program without WWW::Mechanize::Firefox and MozRepl does work fine.
The problem has obviously been narrowed down to PAR::Packer not liking MozRepl, any idea what it might be?
PAR::Packer sometimes has a hard time identifying which modules need to be included in a PAR package in order to fulfill all of the requirements of the program you are trying to package.
It copes OK if the dependancies are loaded via plain 'use', or 'require' statements where the module to be loaded is a literal string, but it won't have much chance if the module is being loaded dynamically with something like:
require $myModuleToLoad;
Browsing the source code of MozRepl and related modules shows that they make heavy use of plugins loaded dynamically. I suspect that some of these are not being packaged.
You can manually specify module(s) to be included in the PAR package by adding -M Module::Name to the pp command line for each of the modules to be added (replacing Module::Name with the actual module name of course).
The hard part might be identifying which modules to include. One way to do this is to temporarily add something like this to the end of your script:
END { print "$_ -> $INC{$_}\n" foreach sort keys %INC; }
then run your script normally, not through PAR. It should list all the modules that were loaded. You can compare that with the actual modules present in the PAR package and add the missing ones using the -M option to pp.
You can see the modules inside your PAR file by opening it with an unzipping tool, such as 7zip. Or in Linux:
unzip -l {parfile}
I am currently trying to create/generate a CSV file using one of three classes:
use Class::CSV;
use Text::CSV;
use Text::CSV_XS;
Though when I try and run it, to check my code I come up with the same error message:
Can't locate Class/CSV.pm in #INC (#INC contains: C:/Per/site/lib C:/Perl/lib .) at C:\Users\<DIRECTORY> - <DIRECTORY>.file.pl line1
I have tried searching for the files though I haven't had any luck. Has anyone else come up against this problem? I have looking in the Directory and the CSV.pm file does exists.
Assuming that Class::CSV is installed on your system, your library search path is incomplete. (Your error message lists C:/Per/site/lib as a search lib, which looks like a typo for C:/Perl/site/lib, which you might want to look into.)
You need to locate the correct CSV.pm file where the library is located. For example, if it's found in:
C:/Perl/lib/foo/Class/CSV.pm
Then you have one of the following options.
Modify the environment for Perl or the invocation so that this is set (assuming my Windows skill haven't expired completely, someone feel free to edit and correct if I get the syntax wrong):
PERL5LIB=%PERL5LIB%;C:/Perl/lib/foo
You can use the -I option to perl to add the path:
perl -IC:/Perl/lib/foo my-app.pl
You can use the use lib command in the program itself to add the search path:
use lib 'C:/Perl/lib/foo';
use Class::CSV;
# etc.
You probably don't have these modules installed.
run this in your shell
perl -MCPAN -e shell
then run
install Class::CSV
I'm assuming that you found these classes on CPAN
You can simply run the following command
perl -MCPAN -e 'install Class::CSV'
to run
install Class::CSV in CPAN shell.
How can I set where Perl looks for modules in Apache httpd.conf file on OSX?
I've installed several modules via CPAN, which were installed successfully in
/opt/local/lib/perl5/site_perl/5.8.9
I can verify this via perldoc perllocal
If I run perl -V on the command line, I get (among other dirs):
#INC:
/opt/local/lib/perl5/site_perl/5.8.9/darwin-2level
/opt/local/lib/perl5/site_perl/5.8.9
When I run a perl script as CGI via Apache, however, I get errors that the modules I'm useing can not be found. The list of dirs being included in #INC do not match my local perl configuration.
[error] [client 127.0.0.1] Can't locate Spreadsheet/ParseExcel.pm in #INC (
#INC contains:
/Library/Perl/Updates/5.8.8
/System/Library/Perl/5.8.8/darwin-thread-multi-2level
/System/Library/Perl/5.8.8
/Library/Perl/5.8.8/darwin-thread-multi-2level
/Library/Perl/5.8.8
/Library/Perl
/Network/Library/Perl/5.8.8/darwin-thread-multi-2level
...
How is #INC getting set when running perl as CGI on OSX - and how do I override it?
The initial value of #INC is hardcoded when perl is built, but it can be modified in a number of ways. The most convenient here are
SetEnv PERL5LIB ...
from within the Apache configuration, or using
use lib qw( ... );
from within the Perl script.
That said, it's not safe to use modules installed using Perl 5.8.9 with Perl 5.8.8 (although the other way around is safe). Even worse, one appears to be a threaded Perl and the other one isn't. Modifying #INC is simply not going to work.
You need to install the module using the same perl as the one you intend to use to run the script, or you must run the script using the same perl as the one used to install the module.
I'm working on installing a perl module (not using CPAN) on a Linux machine. When I run the command:
perl Build.PL
I get the following error:
ERROR: Missing required field 'dist_abstract' for metafile
Could not get valid metadata. Error is: Invalid metadata structure.
Errors: Missing mandatory field, 'abstract' (abstract) [Validation: 1.4],
value is an undefined string (abstract) [Validation: 1.4]
at /usr/local/share/perl5/Module/Build/Base.pm line 4559
Could not create MYMETA files
I've tried Googling bits and pieces of this error but haven't found any solutions. Just looking for a clue as to what might be causing this error.
Here's a link to a zip file containing the files required to install it:
https://oncourse.iu.edu/access/content/user/brilewis/Filemanager_Public_Files/DataDownloader.zip
First at all please make sure you have package Module::Build installed.
You need ungzip few gzipped files in this package. I don't realize why author gzipped them:
gzip -d *.gz
I really don't know why author archived each install file. It looks like some mistake to me.
Than you can install all dependencies (this module requires some):
./Build installdeps
And then finally install module itself:
./Build
./Build test
./Build install
However I must warn you that this module packaged in a bit strange way and there's no guarantee it works.
The NAME section of the module does not have a - in it, e.g.,
=head1 NAME
Foo::Bar implements a Foo framework.
will fail, but if you make it
=head1 NAME
Foo::Bar - implements a Foo framework.
then it will work.
Do you have root access on your machine? Can you use the cpan utility to build and install your module. Using cpan is fairly straight forward:
$ cpan
After that, it will do a lot of configuration, simply take the default values. When it finishes, it'll come to a cpan> prompt. All you have to do there is type this:
cpan> install Module::Name
Where Module::Name is the module you're trying to install. Check the CPAN archive to get the name of your module.
If there are any dependencies, CPAN will ask if you want to download and install those. Say Yes, and CPAN will install the dependencies, then your module.
Using cpan is the best way to install third party modules you find in the CPAN archive. It takes care of all the dependencies, testing, and building for you.
Try installing through CPAN, and then see if you still have your issues.
I need to install two Perl modules on a web host. Let's call them A::B and X::Y. X::Y depends on A::B (needs A::B to run). Both of them use Module::Install. I have successfully installed A::B into a non-system location using
perl Makefile.PL PREFIX=/non/system/location
make; make test; make install
Now I want to install X::Y, so I try the same thing
perl Makefile.PL PREFIX=/non/system/location
The output is
$ perl Makefile.PL PREFIX=/non/system/location/
Cannot determine perl version info from lib/X/Y.pm
*** Module::AutoInstall version 1.03
*** Checking for Perl dependencies...
[Core Features]
- Test::More ...loaded. (0.94)
- ExtUtils::MakeMaker ...loaded. (6.54 >= 6.11)
- File::ShareDir ...loaded. (1.00)
- A::B ...missing.
==> Auto-install the 1 mandatory module(s) from CPAN? [y]
It can't seem to find A::B in the system, although it is installed, and when it tries to auto-install the module from CPAN, it tries to write it into the system directory (ignoring PREFIX). I have tried using variables like PERL_LIB and LIB on the command line, after PREFIX=..., but nothing I have done seems to work.
I can do make and make install successfully, but I can't do make test because of this problem. Any suggestions?
I found some advice at http://servers.digitaldaze.com/extensions/perl/modules.html to use an environment variable PERL5LIB, but this also doesn't seem to work:
export PERL5LIB=/non/system/location/lib/perl5/
didn't solve the problem.
The answer is local::lib, but you probably already know that :)
OK, the following prescription did it:
perl Makefile.PL --skipdeps --no-manpages PREFIX=/non/system/location INSTALLSITELIB=/non/system/location/lib INSTALLSITEBIN=/non/system/location/bin INSTALLMAN1DIR=/non/system/location/man/man1 INSTALLMAN3DIR=/non/system/location/man/man3
This is just "monkey see monkey do" but now make test works.
The --skipdeps option here suppresses a convenient feature/exasperating problem with Module::Install where it tries to use CPAN.pm to download missing modules.
The --no-manpages is supposed to stop it installing man pages but it doesn't work.
Because this is the top link i thought i'd update with my experience (which has taken a while to get working, hence updating the 7 year old post).
first run perl -le 'print join $/, #INC'
add (note, no / at the end!!)
export PERL5LIB=/nonstddir/scripts/modules/lib/site_perl:/nonstddir/scripts/modules/lib
run perl -le 'print join $/, #INC' make sure the new dirs are added. this makes it work. if you add a / at the end of the path, the INC entry will look weird and wrong. Mine had a // in the middle.
When done and working, mine looks like
