分享：解决pip更新报错File "C:\Python36-32\Scripts\pip36.exe\__main__.py", line 5, in ImportError:

需求， 新装python3.6.0。因为本地已存在python3.7.1，所以修改直接修改了python.exe ---> python36.exe

pip.exe --> pip36.exe

 

随后使用pip36 安装模块，提示版本pip 版本过低，随后使用 python36 -m pip install --upgrade pip  更新pip。

之后就是报这个错：

D:\final_aa\1819>pip36
Traceback (most recent call last):
  File "c:\python36-32\lib\runpy.py", line 193, in _run_module_as_main
    "__main__", mod_spec)
  File "c:\python36-32\lib\runpy.py", line 85, in _run_code
    exec(code, run_globals)
  File "C:\Python36-32\Scripts\pip36.exe\__main__.py", line 5, in
ImportError: cannot import name 'main'

解决办法：

cd 到 C:\Python36-32\Scripts\ 目录下：  发现有 pip.exe  pip3.exe  pip36.exe ,删除前两个文件，保留想要的pip36.exe

随后测试，成功。

C:\Python36-32\Scripts>pip36 -V
pip 19.1.1 from c:\python36-32\lib\site-packages\pip (python 3.6)
