Question

我尝试在answer中在cygwin中安装Perl模块失败了。我有以下错误：

$ perl -MCPAN -e shell
Can't locate CPAN.pm in @INC (you may need to install the CPAN module) (@INC   contains: /usr/lib/perl5/site_perl/5.22/x86_64-cygwin-threads /usr/lib/perl5/site_perl/5.22 /usr/lib/perl5/vendor_perl/5.22/x86_64-cygwin-threads /usr/lib/perl5/vendor_perl/5.22 /usr/lib/perl5/5.22/x86_64-cygwin-threads /usr/lib/perl5/5.22 .).
BEGIN failed--compilation aborted.

如何在我的cygwin中获得cpan？

还有一些其他细节。实际上我的目的是在answer中安装ack。但是，它没有用。安装后我遇到了错误：

$ ack
Can't locate filetest.pm in @INC (you may need to install the filetest module) (@INC contains: /usr/lib/perl5/site_perl/5.22/x86_64-cygwin-threads /usr/lib/perl5/site_perl/5.22 /usr/lib/perl5/vendor_perl/5.22/x86_64-cygwin-threads /usr/lib/perl5/vendor_perl/5.22 /usr/lib/perl5/5.22/x86_64-cygwin-threads /usr/lib/perl5/5.22 .) at /home/loom/bin/ack line 218.
BEGIN failed--compilation aborted at /home/loom/bin/ack line 218.

以下是我尝试找到cpan

$ cpan
-bash: cpan: command not found

$ ll /usr/lib/perl5/5.22/CPAN.pm
ls: cannot access '/usr/lib/perl5/5.22/CPAN.pm': No such file or directory

重新安装perl帮助。
