Linux命令行輸入「perl -MCPAN -e shell」進入perl界面，而後輸入「install Perl4::CoreLibs」安裝相應模塊

→ Qftm ← :~/桌面# perl -MCPAN -e shell

CPAN.pm requires configuration, but most of it can be done automatically.
If you answer 'no' below, you will enter an interactive dialog for each
configuration option instead.

Would you like to configure as much as possible automatically? [yes] yes


Autoconfiguration complete.

commit: wrote '/root/.cpan/CPAN/MyConfig.pm'

You can re-run configuration any time with 'o conf init' in the CPAN shell
Terminal does not support AddHistory.
