Perl's module judgment and installation

First, determine whether the module has been installed: (reference:Http://cooloo.lofter.com/post/1906f2_5eabbe)

Perl " print\ "Module installed\n\" "

Second, how to install the module: (Reference:http://jingyan.baidu.com/article/e3c78d646c118d3c4c85f5c8.html)

1. Check if the CPAN package is installed:

#rpm-qa | grep Perl-cpan

2, if not installed, then install:

#Yuminstallperl-cpan*

3, after the installation is complete, you can install the corresponding module by CPAN. For example, I want to install the Archive::zip module:

#cpan Archive::zip

4. After the installation is complete, review the documentation:

#perldoc Archive::zip
