解决 Cannot open D:\Program Files\Anaconda3\Scripts\pip-script.py 问题

安装Pyhton版openCV时，首先要更新pip版本，运行：

 python -m pip install --upgrade pip

首先报错：

为了解决这个问题，在网上查找相关资料时输入：

pip --default-timeout=100 install -U pip

这时报错：

Cannot open D:\Program Files\Anaconda3\Scripts\pip-script.py

这个问题还是pip安装的问题，所以可以在命令行窗口(或者win+r) 输入：

easy_install pip

就可以了！
