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 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 need to run a perl script to gather system information that will be deployed and executed on different unix servers.
Right now I am writing it and testing it, and I'm receiving this error.
Can't locate XML/DOM.pm in #INC (#INC contains: /usr/local/lib64/perl5
/usr/local/share/perl5 /usr/lib64/perl5/vendor_perl
/usr/share/perl5/vendor_perl /usr/lib64/perl5 /usr/share/perl5 .) at
test.pl line 7. BEGIN failed--compilation aborted at test.pl line 7.
So I am simply using XML::DOM which should be part of Perl but it isn't for this version on this particular server which is 5.10.1.
Anyways, is there a way I can create and design my script and package modules into it while keeping the .pl extension, which is the requirement for this script?
If the modules don't require compiled libraries, you can include them by copying the text out of the module into your .pl file. That's a horrible hack but it should work.
Perl modules should contain a package statement that gives them their name. When you get to your main program section you'll need a package main; statement of your own.
You can put the modules in any directory, and then include this directory to be included in the search for modules via the lib pragma. Be aware that a module Foo::Bar has to be in the file MY-ROOT/Foo/Bar.pm and may not be in MY-ROOT/Bar.pm, where MY-ROOT is your module directory.
use lib 'MY-ROOT';
use Foo::Bar;
However, this only works for pure-Perl modules, and doesn't support XS.
In lieu of using the lib pragma as amon suggests, consider installing perlbrew and cpanminus which is designed to work hand-in-hand to add and/or update modules.
perlbrew is designed to be leveraged by specifying #!/usr/bin/env perl as the interpreter line in your Perl scripts while adding a line like source ~/perl5/perlbrew/etc/bashrc to your ${HOME}/.bash_profile to locate the local version of Perl you want.
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.
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
/nonstddir/scripts/modules/lib/site_perl/5.8.4/sun4-solaris-64int
/nonstddir/scripts/modules/lib/site_perl/5.8.4

I am running a script which requires the Curl.pm lib in order to work. I used YUM to install the library and now I am trying to have my script use it, but I keep getting the error

Which one of the paths above needs to be included in my #INC directory? I had thought that the code below would solve the problem when placed at the top of my script, but I am still getting the same error #INC error.
BEGIN {
unshift(#INC, '/usr/lib/libcurl.so.3');
use WWW::Curl;
}
When I type
cpan> i /WWW::curl/
I get the following list below. I'm still stumped. I want to use WWW::curl and I don't know which of the paths below (or above) to add to #INC ! It looks like it's already installed. What do I do from here?
cpan> i /WWW::curl/

You have installed the curl library. To install the WWW::Curl module do this:
yum install perl-WWW-Curl
You installed curl which is not the same thing as WWW::Curl.
You need to install the Perl module WWW::Curl. You should first search your OS specific package repositories for the module. If you cannot find it there, use cpanm to install it:
$ cpanm WWW::Curl

I am going to ignore that chaos that I see and simply answer the question:
You don't add libraries to #INC, you add directories. The directories you add contain Perl modules, i.e. *.pm files.
To do that, you simply use use lib. If the directory you want to add is /foo/bar:
use lib qw| /foo/bar |;
