Django manage.py runserver 命令不起作用答案

【问题标题】：Django manage.py runserver command does not workDjango manage.py runserver 命令不起作用

【问题描述】：

所以我下载了 python（最新版本）并检查了所有内容并将其添加到 PATH。我安装了 django，创建了我需要的所有内容，获取了 django 文件，但是当我运行 python manage.py runserver 它 ptinys 很多东西，但最终它会打印出来

我对 django、pip 或 python shell 一无所知，我正在学习一个教程，但这对我不起作用。

ModuleNotFoundError: No module named 'djangoproject'

它应该可以正常运行并运行服务器。

【问题讨论】：

你重命名你的项目了吗？
实际上它创建了一个名为 djangoproject 的文件夹，其中包含 manage.py 和另一个名为 djangoproject 的文件夹。我刚刚创建了一个 djangoproject，其中包含所有文件 + manage.py。
您是否将第二个“djangoproject”文件夹中的内容移动到与“manage.py”相同的级别？如果你这样做了，那么你破坏了文件结构。

标签： python django

【解决方案1】：

您的 Django 文件结构应如下所示：

djangoproject/
    manage.py
    djangoproject/
        __init__.py
        settings.py
        urls.py
        wsgi.py

__init__.py 告诉 Python 将父目录视为一个模块。

ModuleNotFoundError: No module named 'djangoproject'

通过重新排列文件夹结构，您已阻止 Python 将该文件夹视为一个模块。 Manage.py 需要该模块来执行其操作。
