按照水哥的说法，python使用的是3.7.6，但是在安装
pip install opencv-python -i https://pypi.tuna.tsinghua.edu.cn/simple 回车
这一步进行到一半报错， Building wheel for opencv-python (PEP 517) … error 下面还有些 Ninja等字样。
然后百度了搞了下，直接
Traceback (most recent call last):
File “d:pythonlibrunpy.py”, line 193, in _run_module_as_main
“main”, mod_spec)
File “d:pythonlibrunpy.py”, line 85, in run_code
exec(code, run_globals)
File "D:pythonScriptspip.exe_main.py", line 5, in
ModuleNotFoundError: No module named ‘pip’
分析原因是pip版本低了，然后现在pip被我弄崩了。看了
通过一下两条命令进行修复和升级。
