Can't locate getopts.pl in @INC (@INC contains: /etc/perl /usr/local/lib/x86_64-linux-gnu/perl/5.28.1 /usr/local/share/perl/5.28.1 /usr/lib/x86_64-linux-gnu/perl5/5.28 /usr/share/perl5 /usr/lib/x86_64-linux-gnu/perl/5.28 /usr/share/perl/5.28 /usr/local/lib/site_perl /usr/lib/x86_64-linux-gnu/perl-base) at xxxx.pl line 10.

Cause of error

getopts.pl is a Perl 4 core library but no longer included in current Perl 5 distributions.

Solve the error

Linux命令行输入“perl -MCPAN -e shell”进入perl界面，然后输入“install Perl4::CoreLibs”安装相应模块

 → 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.
