Re: Install CPAN module to another perl version

To install, this ought to work /path/to/perl/bin/cpan Module Module

To install, this ought to work /opt/perl-version/bin/cpan Module Module

To run your program you can use /opt/perl-version/bin/perl program.pl

Or have as your shebang (first line in your file) #!/opt/perl-version/bin/perl -- then you can run the file like by typing /path/to/your/file.pl or ./file.pl

Or prepend these dirs to your $PATH (this program will print them, you export in your shell or .bashrc/.profile as shown below)

#!/opt/perl-version/bin/perl --
use Config;
for my $bin( @Config{qw/ sitebin vendorbin bin/} ){
    $seen{$bin}++ or print $bin; }
}
__END__
export $PATH=/opt/perl-version/bin;...;...;...;$PATH
[download]

then perl yourprogram.pl runs /opt/perl-version/bin/perl yourprogram.pl

then a shebang of #!/usr/bin/env perl -- runs /opt/perl-version/bin/perl yourprogram.pl

Running your code from shell is discussed in the following Behind the GUI lives the Shell and perlintro / perlrun and UNIX Man Pages env, export

Re^2: Install CPAN module to another perl version by Martin90 (Sexton) on Aug 14, 2014 at 21:36 UTC
Thanks for replies, unfortunately perl doesn't see new installed module. I added PATH="/opt/perl-5.16/bin:$PATH" to $PATH variable, saved. When I ask: "which perl" I get repsonse "/opt/perl-5.16/bin/perl", when I ask: "which cpan", I get resposne "/opt/perl-5.16/bin/cpan" #Hmm is it ok ? Should CPAN be located there ? Then I install my module via "CPAN INSTALL MODULE" the whole proces goes ok, but my app doesn't see this new module in @INC and return: Can't locate MODULE.pm in @INC (@INC contains: Plugins Modules . /usr/lib/perl5/site_perl/5.8.8/i386-linux-thread-multi /usr/lib/perl5/site_perl/5.8.8 /usr/lib/perl5/site_perl /usr/lib/perl5/vendor_perl/5.8.8/i386-linux-thread-multi /usr/lib/perl5/vendor_perl/5.8.8 /usr/lib/perl5/vendor_perl /usr/lib/perl5/5.8.8/i386-linux-thread-multi /usr/lib/perl5/5.8.8) (..) It is still looking in "/usr/lib/perl5", whats wrong ? PS: When I change my shebang from "#!/usr/bin/env perl " to "#!/opt/perl-5.16/bin/perl" I get Internal Server Error. What's wrong ? ;/	[reply]

What's wrong ? ;/ Well, the webserver is not your shell, so $PATH is not the same ... use full paths, and then work through the checklists , brian's Guide to Solving Any Perl Problem, CGI Help Guide , Troubleshooting Perl CGI scripts ... More generic advice :) On debugging, verify everything, talk to teddybear ... checklists and more	[reply]

SOLVED, thank you ;) As it turned out #!/opt/perl-5.16/bin/perl was right shebang.	[reply]
