python - 导入错误: cannot import name 'main' when trying to download any python library

Question

我已经能够正常下载 python 库一段时间了，但是发生了这种情况，我已经尝试了所有解决方案，但我认为这是针对我的情况的

我试图下载漂亮的汤，收到一个错误，说它无法正确加载“egginfo.py”或类似的内容，我发现可以通过升级 setuptools 来修复该错误。我这样做了并得到了这个:

D:\Python3_64\Scripts>pip install beautifulsoup
Traceback (most recent call last):
  File "d:\python3_64\lib\runpy.py", line 193, in _run_module_as_main
    "__main__", mod_spec)
  File "d:\python3_64\lib\runpy.py", line 85, in _run_code
    exec(code, run_globals)
  File "D:\Python3_64\Scripts\pip.exe\__main__.py", line 5, in <module>

导入错误:无法导入名称“main”

使用简易安装:

D:\Python3_64\Scripts>easy_install beautifulsoup

During handling of the above exception, another exception occurred:

  File "d:\python3_64\lib\site-packages\setuptools\command\easy_install.py", 
    line 884, in install_eggs

因此，我无法再下载任何类型的 Python 库。

我已经尝试过:

-删除旧版本的 python

-升级安装工具

-使用 pip3

-使用 --user 标志安装

-运行提升的提示符并尝试安装

-使用easyinstall

-卸载并重新安装python

感谢所有帮助。
