python – pip3错误 – ‘_NamespacePath’对象没有属性’sort’

我试图通过pip3安装一个包,我收到了这个错误.我运行的每个pip / pip3命令都给我这个错误 –

alexg@hitbox:~$pip3 -V
Traceback (most recent call last):

我已经尝试根据一些答案运行pip3 install –upgrade pip setuptools,但每个pip命令都会给我错误.我被困住了,什么也做不了.

可能导致它的原因,以及如何解决这个问题？

我使用Python 3.5.2在Ubuntu 16.04上

解决方法:

我遇到了与python 3.5.2和pip3(9.0.1)相同的问题.我通过以下解决方法修复了它：https://github.com/pypa/setuptools/issues/885#issuecomment-307696027

更具体地说,我编辑了这个文件的第2121~212行：“sudo vim /usr/local/lib/python3.5/dist-packages/pip/_vendor/pkg_resources/__init__.py”

#orig_path.sort(key=position_in_sys_path)
#module.__path__[:] = [_normalize_cached(p) for p in orig_path]
orig_path_t = list(orig_path)
orig_path_t.sort(key=position_in_sys_path)
module.__path__[:] = [_normalize_cached(p) for p in orig_path_t]
