不能导入Django，您确定PYTHONPATH环境变量已安装并可用吗？您是否忘记激活虚拟环境？

查看环境变量

发现系统的环境变量PATH里没有python，然后去用户环境变量，发现PAYH内容如下：

用户PATH内容
D:\anaconda3
D:\anaconda3\Library\mingw-w64\bin
D:\anaconda3\Library\usr\bin
D:\anaconda3\Library\bin
D:\anaconda3\Scripts
D:\python\Scripts\
D:\python\

这样先找的就是anaconda里的python

---

解决方法

将D:\python\上移到第一个，然后确定。

用户PATH更改后
D:\python\
D:\anaconda3
D:\anaconda3\Library\mingw-w64\bin
D:\anaconda3\Library\usr\bin
D:\anaconda3\Library\bin
D:\anaconda3\Scripts
D:\python\Scripts\
