【问题描述】：

我一直在使用 pip 3 为 python 3（numpy 等）安装一系列基本包，一切都很好。然后我尝试安装 tensorflow-gpu，我得到了

user@computer:~$ pip3 install --upgrade tensorflow-gpu
Traceback (most recent call last):
  File "/usr/lib/python3/dist-packages/pip/_vendor/__init__.py", line 33, in vendored
    __import__(vendored_name, globals(), locals(), level=0)
ImportError: No module named 'pip._vendor.pkg_resources'

During handling of the above exception, another exception occurred:

我清除了 python3-pip 并重新安装它，这没有帮助。

编辑：如果我只是在终端中运行pip3，我会得到同样的错误。

EDIT2：好的，为了清楚起见，我无法将 pip3 用于任何任务。运行 pip3 install setuptools 会出现同样的错误。我也没有在假定的重复问题中找到任何解决方案。

Possibly related issue
@Norrius ，我看不出它们有什么关系？
您在尝试使用 pip 时也会收到 No module named pkg_resources。请注意，我说的是可能相关，毕竟可能没有相关性。
installing google-cloud using pip fails的可能重复
@phd 我无法运行 pip3 install --upgrade setuptools。我不能用 pip3 做任何事情！

【解决方案1】：

AttributeError: '_NamespacePath' object has no attribute 'sort'

这看起来好像你错过了另一个你可以尝试的模块

pip3 install setuptools
