Django启动报错：Couldn‘t import Django. Are you sure it‘s installed and available on your PYTHONPATH...

错误信息如下：

PS F:mysitemysite> python manage.py runserver
Traceback (most recent call last):
  File "manage.py", line 8, in 
    from django.core.management import execute_from_command_line
ModuleNotFoundError: No module named 'django'

The above exception was the direct cause of the following exception:

Traceback (most recent call last):
  File "manage.py", line 10, in 
    raise importError(
importError: Couldn't import Django. Are you sure it's installed and available on your PYTHonPATH environment variable? Did you forget to activate a virtual environment?
PS F:mysitemysite> 

错误信息翻译：

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？

去看看环境变量：

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：

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。

重启VSCode。
