有人可以帮我吗？

解决方案

更改我的项目名称，问题是您正在使用

您可以看到Environment变量仍然具有以前的值，只需单击角落的图标以编辑 DJANGO_SETTINGS_MODULE 变量。

然后添加您的新项目名称 newname ，其中包含 settings.py 文件。

就是这样。

I changed the name of my django project from oldname to newname using Pycharm's refactor > rename. I have scoured through the project and it seems to have changed the name everywhere. But when I try runserver, here's what I get,

Traceback (most recent call last):

ModuleNotFoundError: No module named 'oldname'

Can someone help me with this?

解决方案

I got the same error when changing my project name, the problem is that you're running the server using PyCharm, isn't it? Hopefully you created your project using PyCharm with Django Support. First of all add the below settings to your wsgi.py and manage.py files,

os.environ.setdefault('DJANGO_SETTINGS_MODULE', 'oldname.settings')

to

os.environ.setdefault('DJANGO_SETTINGS_MODULE', 'newname.settings')

Then go to your settings.py and change the below settings,

ROOT_URLCONF = 'oldname.urls
WSGI_APPLICATION = 'oldname.wsgi.application'

to

ROOT_URLCONF = 'newname.urls
WSGI_APPLICATION = 'newname.wsgi.application'

If you didn't get PyCharm's Django Support, this solution should be performed otherwise you will get the same error again. You can try this by using some other terminal without getting PyCharm's Django Support and running your server with python manage.py runserver command. If your project doesn't have any other errors you can see this solution is working. Then I realized something wrong with PyCharm's Django Support, the help that I have provided is only for who are using PyCharm's Django Support.

1. Go to your Project and click the Edit Configuration Settings.

2. You can see the Environment variable still has the previous values, just click the icon in the corner to edit the DJANGO_SETTINGS_MODULE variable.

3. Then add your new project name newname, which contains the settings.py file.

That's it.
