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，它会给出错误：

no such file and directory

因此，我复制了manage.py文件，并将其粘贴到写入的路径下，当我再次键入时，它显示了一个奇怪的长错误，我尝试了所有路径，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，这给了我一个奇怪的长错误，即

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

Answer 1

因为你刚开始学习。用python（pycharm professional）创建一个新的Django项目，然后再次启动该应用程序，不要将manage.py文件复制到任何地方。 同时运行

$ django-admin.py startproject Yourprojectname

在您运行

python manage.py runserver
