| - | ==== To install Modules Locally ==== | ||
| - | Best way to install local module is to install module "local::lib".\\ | ||
| - | [[http://search.cpan.org/~apeiron/local-lib/ | CPAN Local::lib ]]\\ | ||
| - | But you can also manually do it. | ||
| - | |||
| - | **First export your username** | ||
| - | |||
| - | <code bash> | ||
| - | export username=ketan | ||
| - | </code> | ||
| - | |||
| - | <note warning>Still you have to modify / change "$username" manually at many places</note> | ||
| - | |||
| - | **create the .cpan directories** | ||
| - | |||
| - | <code oobas> | ||
| - | mkdir $HOME/.cpan/ | ||
| - | mkdir $HOME/.cpan/CPAN/ | ||
| - | # This is so it ignores the global CPAN config | ||
| - | |||
| - | echo "\$CPAN::Config->{cpan_home}='/home/$username/.cpan';" > /home/$username/.cpan/CPAN/MyConfig.pm | ||
| - | </code> | ||
| - | Then Execute a CPAN shell | ||
| - | |||
| - | <code oobas> | ||
| - | perl -MCPAN -e shell | ||
| - | OR | ||
| - | cpan | ||
| - | </code> | ||
| - | Then when in the shell type: | ||
| - | |||
| - | <code oobas> | ||
| - | o conf init | ||
| - | </code> | ||
| - | <note>to reconfigure CPAN, replace all */root/.cpan/* with /home/$username/.cpan/*</note> | ||
| - | |||
| - | change the makepl_arg so it should look like. | ||
| - | |||
| - | <code bash | /home/$username/.cpan/CPAN/MyConfig.pm> | ||
| - | 'makepl_arg' => q[INSTALLDIRS=site PREFIX=/home/$username/perl/], | ||
| - | </code> | ||
| - | Finally the env variable PERL5LIB needs to point to the new module installation paths: | ||
| - | |||
| - | <code oobas> | ||
| - | export PERL5LIB="/home/$username/perl/share/perl/custom_lib/:/home/$username/perl/lib/perl/custom_lib/"; | ||
| - | </code> | ||
| - | and then you should be able to use CPAN to install modules. | ||
| - | |||
| - | I then modified following file | ||
| - | |||
| - | <code bash | ~/.bashrc> | ||
| - | export PERL_LOCAL_LIB_ROOT="/home/$username/perl"; | ||
| - | export PERL_MB_OPT="--install_base /home/$username/perl"; | ||
| - | export PERL_MM_OPT="INSTALL_BASE=/home/$username/perl"; | ||
| - | export PERL5LIB="/home/$username/perl/share/perl/custom_lib/:/home/$username/perl/lib/perl/custom_lib/"; | ||
| - | export PATH="/home/$username/perl/bin:$PATH"; | ||
| - | </code> | ||
