我无法升级Perl。

这个特定的依赖性错误应该在1.000000中修复，即因为perl 5.10上的dep已被删除。

https://metacpan.org/source/KENTNL/Path-IsDev-1.000000/Changes#L51

虽然依赖本身的原因实际上是“三部分版本在旧版本上没有得到很好的支持”。

代码中没有任何内容明确需要它，但它更多的是前向声明支持。 Perl 5.8已经很久了，你真的应该尽力而为，以取决于它。

我实际上计划尽快废除Path::FindDev的3部分版本，它需要进行一些严肃的检修，因为它现在很糟糕，当版本在某个时候进入1.000000时下周左右，perl依赖应该同样下降。

但是，如果你想要一个临时解决方案：

cpanm --prompt Path::IsDev Path::FindDev

然后在询问你是否想要建立的时候按“y”。

cpanm --prompt Path::FindDev
