Installing CPAN without root access

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

I am trying to install CPAN so I can install some CPAN Perl modules. I don't have root access so I am trying to install everything on this remote server locally under my user id.

I tried the yum command: yum -y install perl-CPAN which obviously doesn't work because I am not a root user.

I also tried installing CPAN without yum command, which just returns an error saying CPAN.pm can't be located.

I did my research and gathered info that in order to install these modules locally, I would need to set proper environment variables under perl5 directory. I am not sure how to do that. Also, every time I unzip a tar file for any module and try to run the install command, it returns an error saying that module's .pm file is not located.

Any suggestions or directions on how I can go about doing this? Thanks

Hi, the solution depends heavily on the question whether you want to stick to the system's perl installation or if you want a current Perl version too. If you say: Hey, I start by own directory tree for modules why should I not also install a perl for my own, than have a look at http://perlbrew.pl/. (App::perlbrew) If you say: No, please, I just want some modules on my own, than have a look at local::lib and for nice installation to App::cpanminus. UPDATE: I forgot something. The local::lib thing is meanwhile integrated into the App::perlbrew. So you can think of the App::perlbrew way as a kind of superset. McA	[reply]

I tried installing App::perlbrew but I keep getting error with the curl command they have provided on the website that curl couldn't connect to host. Thanks for your help though	[reply]

You probably have an HTTP proxy on your network. Set it in the http_proxy variable. Check the curl man page.	[reply]

Use cpanm and local::lib by dolmen (Beadle) on Sep 11, 2013 at 14:55 UTC
Bootstrap: `$ PATH="$PATH:~/perl5/bin" $ export PERL5LIB=~/perl5/lib/perl5 $ export PERL_MB_OPT="--install_base '$HOME/perl5'" $ export PERL_MM_OPT="INSTALL_BASE=$HOME/perl5" $ curl -L http://cpanmin.us \| perl - -l ~/perl5 App::cpanminus local:: +lib` [download] Then adapt your .profile for local::lib and cpanm by adding this line: `eval $(perl -I$HOME/perl5/lib/perl5 -Mlocal::lib)` [download] Now you can just do: `cpanm any-module`	[reply] [d/l] [select]
