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，无法运行服务器。

Python和PyCharm是新安装的。我已经通过命令pip install Django安装了Django。之后，当我运行命令python manage.py runserver时，它会给我错误：

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，当我再次键入时，它显示了这个奇怪的长错误。我尝试了每个路径，但它给了我一个错误，没有这样的文件和目录，只在一个路径上，这给我一个奇怪的长错，即

Answer 1

python manage.py依赖于settings.py文件中的配置。检查一下你是否还有设置。是的，你可能已经把它删除了，我弄错了。这对我有效

Answer 2

因为你刚开始学习。用python(pycharm-professional(创建一个新的Django项目，然后重新启动应用程序，不要在任何地方复制manage.py文件。也运行

$ django-admin.py startproject Yourprojectname

在运行之前

python manage.py runserver
