scikit-build could not get a working generator for your system. Aborting build.
Building windows wheels for Python 3.7 requires Microsoft Visual Studio 2019.
Get it with "Visual Studio 2017":

Failed building wheel for opencv-python
Running setup.py clean for opencv-python
Failed to build opencv-python
Could not build wheels for opencv-python which use PEP 517 and cannot be installed directly
You are using pip version 19.0.3, however version 21.3.1 is available.
You should consider upgrading via the 'python -m pip install --upgrade pip' command.

2.解决方法
取消anaconda使用的opencv-python包的想法
使用原生python，也就是官网上下载的纯净版本下载，执行pip指令，执行无误，下载成功
