我想在 django 中运行一个新项目，我收到此错误：ModuleNotFoundError: No module named 'C:\\Python39\\Lib\\site-packages\\django\\conf'

Question

我在 windows 上的 virtualenv 中创建了一个项目，然后尝试运行它并发生此错误：

    Traceback (most recent call last):

我尝试在项目中构建 virtualenv，但仍然无法正常工作。

请帮我：）

Answer 1

1. 你必须激活你的 virtualenv

   来源 ~/your_virtual_env_directory/Scripts/activate

   2. 在项目目录中运行命令

   python manage.py runserver

Answer 2

使用 pipenv 制作虚拟环境

脚步：

1.) 使用终端定位您的项目让我们说 cd/desktop/myproject

2.）然后使用以下命令（如果您愿意，可以更改 django 版本）

pipenv install django==3.0.1

然后使用启动虚拟环境

pipenv shell

它会创建你的虚拟环境像这样 (myproject)$

3.) 退出虚拟环境使用

exit

4.) 再次使用相同的虚拟环境

pipenv shell
