使用 pip3:模块“importlib._bootstrap"；没有属性“SourceFileLoader" [英] using pip3: module "importlib._bootstrap" has no attribute "SourceFileLoader"

问题描述

我已经在 Ubuntu 14 上为 python 3.6 安装了 pip.运行之后

I have installed pip for python 3.6 on Ubuntu 14. After I run

sudo apt-get install python3-pip

安装pip3，效果很好.但是，安装后，当我尝试运行时

to install pip3, it works very well. However, after installation, when I am trying to run

pip3 install packagename

安装一个新的包，发生了一些奇怪的事情:

to install a new package, something strange occurs:

File "/usr/lib/python3/dist-packages/pkg_resources.py", line 1479, in <module>
 register_loader-type(importlib_bootstrap.SourceFileLoader, DefaultProvider)
AttributeError: module "importlib._bootstrap" has no attribute "SourceFileLoader"

我好像没做错什么，实在想不出原因.

It seems that I did nothing wrong, and I really cannot figure out the reason.

推荐答案

面临同样的问题.我认为这是因为 python3.6 和 pip3 是从不同的来源安装的.我建议使用 python 的内置工具来安装 pip，即

Faced the same problem. I think this is because python3.6 and pip3 were installed from different sources. I suggest using python's inbuilt facility to install pip i.e

python3 -m ensurepip --upgrade

这应该安装 pip3 和 pip3.x 其中 x 在 python3.x 中.python2 也同样适用.

This should install pip3 and pip3.x where x in python3.x. Same works for python2 also.
