pip安装opencv-python遇到的问题
控制台出现这种情况就是版本过低，需要先升级版本，命令pip install -upgrade pip
出现：Script file ‘D:\Python\Anaconda3\Scripts\pip-script.py’ is not present 原因就是升级pip过程中删除了原对应的文件 缺少升级后的pip及对应目录下的pip-script的python文件，缺少什么我们就加什么文件就解决问题了。cd命令切换到Scripts文件，使用命令conda install pip
重新用pip install opencv-python 使用pip list检查安装是否成功
树莓派 pip安装opencv-python的正确实践
python -m pip install opencv-python -i http://pypi.douban.com/simple/ --trusted-host pypi.douban.com """许多教程里的代码都是用的老版本，函数API的接口有时不一样，如果不指定版本的话会安装最新版本，代码得大#幅修改，给入门增加阻力。#安装指定版本： pip install opencv-python==3.4.3.18记录备查"""完整安装过程如下
以后大家参考
