CPAN method
perl -MCPAN -e shell (to get an interactive CPAN shell)
perl -MCPAN -e 'install Time::JulianDay' (if you know the name of
the module, you can install it directly without interacting with
the CPAN shell)
tips:
如何检查一个perl模块是否已经安装了？
可以使用perldoc moduleName检查。
不过首先要现安装perl-doc
$sudo apt-get install perl-doc
$ perldoc CGI
Try it with a module that does not
exist and you’ll get an error message.
$ perldoc Llamas
$ No documentation found for
"Llamas".
最佳实践：使用MCPAN的m moduleName命令
