perl - 如何在 Cygwin 上为 Perl 设置 'use diagnostics'？

Question

我要安装DBD::AnyData这需要 SQL::Statement这需要 Math::Base::Convert .但是，它给了我这个错误

$ cpan install Math::Base::Convert
...
t/overload.t .............. couldn't find diagnostic data in /usr/lib/perl5/5.22/pods/perldiag.pod /home/Chloe/.cpan/build/Math-Base-Convert-0.11-EySfLp/blib/lib /home/Chloe/.cpan/build/Math-Base-Convert-0.11-EySfLp/blib/arch /usr/lib/perl5/site_perl/5.22/i686-cygwin-threads-64int /usr/lib/perl5/site_perl/5.22 /usr/lib/perl5/vendor_perl/5.22/i686-cygwin-threads-64int /usr/lib/perl5/vendor_perl/5.22 /usr/lib/perl5/5.22/i686-cygwin-threads-64int /usr/lib/perl5/5.22 . t/overload.t at /usr/lib/perl5/5.22/diagnostics.pm line 259, <POD_DIAG> line 704.

我已经跑了cpan -u .

CPAN 版本 1.61，Perl 5.22.0

diagnostics模块从 perldoc 文件 perldiag.pod 中获取对消息的解释.这两个都是 perl 的核心部分，但是一些打包系统选择将文档分发到一个单独的包中，即使 perl 安装了也可能不会安装。在 Cygwin 的情况下，这个包是 perl_pods .安装该软件包应该使 diagnostics模块正常工作。
