请再次提出这个问题。
我在Ubuntu 16.04上我试图用pip3安装Kmodes但是我收到了这个错误。我尝试从头开始删除pip / pip3并重新安装它并没有解决问题。
我之前发现过有关同一问题的问题，但它没有像pip3 install --upgrade pip setuptools那样解决。
这个问题的解决方案是什么，我该怎么做才能解决它？

答案 0 :(得分：0)
更改pkg_resources / _init_.py中的行（在我的情况下，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)
