| - | ===== CPAN ===== | ||
| - | |||
| - | ==== 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> | ||
| - | |||
| - | **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/$username/.cpan/CPAN/MyConfig.pm | ||
| - | </code> | ||
| - | Then Execute a CPAN shell | ||
| - | |||
| - | <code oobas> | ||
| - | perl -MCPAN -e shell | ||
| - | OR | ||
| - | cpan | ||
| - | </code> | ||
| - | Then when in the shell type: | ||
| - | |||
| - | <code oobas> | ||
| - | o conf init | ||
| - | </code> | ||
| - | to reconfigure CPAN, replace all \*/root/.cpan/\* with /home/$username/.cpan/* | ||
| - | |||
| - | Then edit ''/home/$username/.cpan/CPAN/MyConfig.pm'' and change the makepl_arg so that it has your PREFIX line as well: | ||
| - | |||
| - | <code oobas> | ||
| - | 'makepl_arg' => q[INSTALLDIRS=site PREFIX=/home/$username/perl/], | ||
| - | </code> | ||
| - | Finally the env variable PERL5LIB needs to point to the new module installation paths: | ||
| - | |||
| - | <code oobas> | ||
| - | export PERL5LIB="/home/$user/perl/share/perl/5.8.4/:/home/$user/perl/lib/perl/5.8.4/"; | ||
| - | </code> | ||
| - | and then you should be able to use CPAN to install modules. | ||
| - | |||
| - | I then modified the Oddmuse script so that the new module install directory was in @INC so that Oddmuse could pick up the modules. Put the following line somewhere near the top | ||
| - | |||
| - | <code oobas> | ||
| - | push @INC,qw(/home/$user/perl/share/perl/5.8.4/ /home/$user/perl/lib/perl/5.8.4/); | ||
| - | </code> | ||
