revendar has asked for the wisdom of the Perl Monks concerning the following question:

Hello Monks, I'm trying to execute a CGI script from Chrome. The cgi handlers are enabled in the webserver. A small Hello world CGI script works when called from browser. I have a CGI script like mentioned below which loads some custom libraries and CPAN libraries which are installed extra

#!/usr/bin/perl use CGI; use Data::Dumper; use lib::MyDatasource; use JSON::XS; print header(); print "Hello world\n";

Ths above code works when I comment lib::MyDatasource(which I have created) and JSON::XS(which i installed from CPAN). Also from UNIX cmd I can execute the script perfectly.

I have tried adding the lib folder to INC path, but in vain.

Please suggest.

    Web servers often run in a different environment than the command-line.

    What I would suggest, since you seem to have Data::Dumper loading fine, is to dump out %ENV and @INC, and compare the results in the web server to your command-line. Look for environment variables that affect the path, such as PATH, PERLLIB/PERL5LIB, etc. You may want to update the web server configuration to set them differently. There are other ways to set paths depending on the web framework you are using. It's also possible for the web server to use an entirely different version of Perl than the command-line, so you might want to check for that too.
