WIN10下直接安装pip install pandas报错 解决 2021-04-12

WIN10下直接安装报错：

C:\Users\Administrator>pip install pandas
'pip' 不是内部或外部命令，也不是可运行的程序
或批处理文件。

解决  ：直接在CMD后输入 ：
C:\Users\Administrator>python -m pip install pandas -i http://pypi.douban.com/simple/ --trusted-host pypi.douban.com
Looking in indexes: http://pypi.douban.com/simple/
