【创建虚拟环境】

 1 # 1.执行命令mkvirtualenv -p python3 smart_api
 2 
 3 # 2.在虚拟环境中装django
 4     pip install django==4.2.13
 5 
 6 # 3. 创建后端项目
 7     1 使用命令
 8             django-admin startproject 项目名
 9         2 pycharm创建--指定刚刚创建的虚拟环境
10             -找到刚刚创建的虚拟环境，加入进来，创建项目即可
11             -路径找到
12                 -1 重启机器
13                 -2 把虚拟环境目录浅一些
14             -3 使用命令创建，使用pycharm打开--》还得指定解释器

 变成smart_api1
