创建项目报错解决方法

1、安装django
2、配置django的环境变量
C:\Users\huojia\AppData\Local\Programs\Python\Python36-32\Lib\site-packages\django
3、运行命令行创建django项目
选好目录，执行django-admin startproject mysites项目名称
项目就被创建了，但是报错，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?
4、卸载django版本，重新安装,没有生效
    pip3 uninstall django
    pip3 install django
5、cmd启动程序python3 manage.py runserver 127.0.0.1:8001
报以下错误，说没有权限
