No module named ‘pip._internal‘

问题描述

在项目编译过程中出现了错误导致编译中断, 错误提示具体如下:

Traceback (most recent call last):
  File "setup.py", line 219, in <module>
    if not is_installed('cython_bbox'):
  File "setup.py", line 177, in is_installed
    from pip._internal.utils.misc import get_installed_distributions
ModuleNotFoundError: No module named 'pip._internal'

然后在自己的python环境中尝试导入报错如下:

解决方案

这意味着依赖关系混乱了，尝试了 pip3 install --upgrade setuptools 等一些方法，未能处理这个问题。
最后我通过重新安装 pip 解决了这个问题。

curl https://bootstrap.pypa.io/get-pip.py -o get-pip.py
sudo python3 get-pip.py
