查看已安装PERL的模块

1、perldoc perllocal

 

2、推荐pmtools里的pminst命令
  

 

3、编写如下标本

   #!/usr/bin/perl

   use ExtUtils::Installed;

   my $inst = ExtUtils::Installed->new();
   print join "\n", $inst->modules();

 

4、Most of them will probably already be available in your installation. You can   check version numbers with the configure script, or if you're still trying to get to that point, check from the command line like this:

     perl -e 'use FileHandle; print $FileHandle::VERSION."\n"'
