How to check and install missing perl modules

• Check if module is installed. Errors mean missing module.
  

  # perl -MModule::Name -e 1

• See documentation of the module if installed.

  # perldoc Module::Name

• Open CPAN shell

  # perl -MCPAN -e shell

• To reconfigure the shell if needed.

  cpan>o conf init

• Install an available module.

  cpan> install HTML::Template

• You can run the Perl CPAN module via command line perl and get it installed in a single line:
  

# perl -MCPAN -e ‘install HTML::Template

• Force install if test fails.

  cpan> force install Module::Name

• To manual install perl modules. Unzip and go to module directory.

# tar -zxvf HTML-Template-2.8.tar.gz

• # perl Makefile.PL# make# make test# make install
