提到几分钟前我在错误的文件夹上安装了 django 并且一切正常..
请帮忙!谢谢!

在主目录根目录下添加以下命令创建环境:
$ python3 -m venv venv此代码将在根目录中创建一个名为 venv 的文件夹。这基本上是虚拟环境文件夹。

然后添加以下命令来激活虚拟环境:
$ source venv/bin/activate

your_project_folder/
 |
 |-- your_main_app_folder/
 |         |
 |         |--Folder_with_controllers/
 |         |            settings.py
 |         |            urls.py
 |         |            ...
 |         | 
 |         |--App_folder/
 |         |--Other_app_folder/
 |
 |--venv/

如果代码运行良好，您的 bash 应该如下所示: (venv) <the_path_for_the_folder> your_project_folder %
激活环境后，您现在可以安装 django 和其他软件包。

Ps:确保您安装并激活不在 your_main_app_folder中的虚拟环境文件夹.
