Windows下配置Python(numpy,opencv)的踩雷历史

原来我还写过这个，贴一下。

C:\Windows\system32>pip list

You are using pip version 7.1.2, however version 21.0 is available.
You should consider upgrading via the 'python -m pip install --upgrade pip' command.

卸载重装了python，又出现了要升级的问题。

一旦升级，又出现invalid syntax问题。

卸载，忽视升级问题，重新安装。

C:\Users\WWW>pip install opencv-python

按照提示安装了skbuild模块，再次尝试安装opencv

出现上述error

‘–trusted-host mirrors.aliyun’

出现上述warning

修改换源地址后，重新安装opencv

更新了setuptools

尝试重新安装numpy，失败，仍然错误

    Complete output from command python setup.py egg_info:Traceback (most recent call last):File "<string>", line 20, in <module>File "C:\Users\WWW\AppData\Local\Temp\pip-build-27jupq9q\numpy\setup.py",

注意到这里有个RuntimError，要求python版本。

尝试使用conda？

安装3.7以上的版本提示错误，注意到KB2533623

解决：

后来用了默认安装，卸载了旧版本记得把C盘的Python文件夹全部删除。

pip3 install -i  scikit-build
pip install SomePackage -i 

Successfully installed numpy-1.20.0 opencv-python-4.5.1.48>

安装成功。
