I want to install perl modules on a shared server on which I do not have root access. How can I do this? They also seem to have an older version of CPAN (it complains about that when running the command), is it possible to update the CPAN command being used from my account without requiring root access?

The easiest method I have found so far is to say
This assumes your profile is named
.profile
, you may need to change that to be.bash_profile
,.bashrc
, etc. After that you can install modules by sayingand simply use them the same way you would if the were installed in the root directories.
What follows is a brief explanation of what the commands above do.
wget -O- http://cpanmin.us
fetches the latest version ofcpanm
and prints it toSTDOUT
which is then piped toperl - -l ~/perl5 App::cpanminus local::lib
. The first-
tellsperl
to expect the program to come in onSTDIN
, this makesperl
run the version ofcpanm
we just downloaded.perl
passes the rest of the arguments tocpanm
. The-l ~/perl5
argument tellscpanm
where to install Perl modules, and the other two arguments are two modules to install.[App::cpanmins
]1 is the package that installscpanm
.local::lib
is a helper module that manages the environment variables needed to run modules in local directory.After those modules are installed we run
to set the environment variables needed to use the local modules and then
to ensure we will be able to use them the next time we log in.
will hopefully cause man to find the man pages for your local modules.
