During handling of the above exception, another exception occurred:

根据网上的处理意见，对
File “e:\wim\project\datanum\lib\site-packages\pip_vendor\pkg_resources_init_.py”, line 1424, in get_metadata
return value.decode(‘utf-8’)
进行修改编码方式，但是多种尝试无果……

网上绝大部分给出意见都是——用编辑器打开Python36\Lib\site-packages\pip\compat\__init__.py，将第75行return s.decode('utf_8') 修改为return s.decode('cp936')
但是，我这边没有这个文件，报错的是\lib\site-packages\pip_vendor\pkg_resources_init_.py", line 1424, 这个文件。

基本上能找到的修正方式都尝试了，依然无法解决……
下面是各种尝试错误提示，请高手指教

根据网上的解决方案，将UTF-8修改为GBK，依然报错
