mac 测试colc的时候Can't locate Moo/Role.pm in @INC (you may need to install the Moo::Role module)

今天在mac上测试colc的时候，出现了下面的问题：

Can't locate Moo/Role.pm in @INC (you may need to install the Moo::Role module) (@INC contains: /usr/local/Cellar/cloc/1.84/libexec/lib/perl5/darwin-thread-multi-2level /usr/local/Cellar/cloc/1.84/libexec/lib/perl5 /usr/local/Cellar/perl/5.30.0/lib/perl5/site_perl/5.30.0/darwin-thread-multi-2level /usr/local/Cellar/perl/5.30.0/lib/perl5/site_perl/5.30.0 /usr/local/Cellar/perl/5.30.0/lib/perl5/5.30.0/darwin-thread-multi-2level /usr/local/Cellar/perl/5.30.0/lib/perl5/5.30.0 /usr/local/lib/perl5/site_perl/5.30.0) at /usr/local/Cellar/cloc/1.84/libexec/lib/perl5/Parallel/ForkManager/Child.pm line 12.

解决方法

 brew unlink perl

然后就可以正常使用了，这里的操作类似于把perl的软连接去掉，想重新把perl链接回来，可以使用

brew link perl
