运行 Django 时出错：ModuleNotFoundError：没有名为“pyshop.settings”的模块

Question

我已经开始学习 Django 并且无法运行服务器。

Python and PyCharm are freshly installed I have installed Django by command pip install Django . 之后，当我运行命令python manage.py runserver它给我错误：

没有这样的文件和目录

所以我复制了manage.py文件并粘贴在写入的路径下，当我再次输入时，它向我显示了这个奇怪的长错误我已经尝试了每条路径，但它给了我一个错误，即只有一个路径上没有这样的文件和目录这给了我一个奇怪的长错误

(venv) C:\Users\Usman Raees\PycharmProjects\pyshop>python manage.py runserver

Answer 1

因为你刚开始学习。 在 python（pycharm 专业版）中创建一个新的 Django 项目并再次启动应用程序，不要将 manage.py 文件复制到任何地方。 还运行

$ django-admin.py startproject Yourprojectname

在你运行之前

python manage.py runserver

Answer 2

python manage.py 依赖于 settings.py 文件中的配置。 检查您是否仍然有 settings.py，您可能已将其删除是我的错误。 那对我有用
