我试图查找异常，但没有找到非常有用的信息。

I tried to look up the exception but I didn't find very useful information.

我也尝试更改Python版本，它没有任何效果。

I also tried to change the Python version but it didn't have any effect.

alias python=/usr/local/bin/python3.5

推荐答案

尝试使用虚拟环境，这样就不需要root权限对于安装，您的项目可以使用不同版本的python软件包。

Try to use a virtual environment, that way you won't need root permission for installation and your projects could use different versions of python packages.
