Python3-pip3:AttributeError:“\u NamespacePath”对象没有属性“sort”

Question

这个问题又来了，请耐心听我说。

我在Ubuntu 16.04上，我试图用pip3安装Kmodes，但我遇到了这个错误。我尝试从零开始删除pip/pip3并重新安装，但没有解决问题。

我找到了以前关于同一问题的问题，但它没有像pip3安装-升级pip setupols那样解决这个问题。

这个问题的解决方案是什么，我能做些什么来解决它？

Answer 1

更改pkg_resources/_init_3;中的行。py（在我的例子中，这是在~/.env/lib/python3.5/site-packages/中）：

orig_path.sort(key=position_in_sys_path)  

到

orig_path = sorted(orig_path, key=position_in_sys_path)
