Django无法识别设置模块

Question

我试图按照this guide设置Django应用程序的设置模块。

我创建了设置模块，其中包含__init__ .py，common.py和dev.py.然而，当我试图python manage.py runserver --settings=settings.dev，我得到的导入错误：

如果我试图python manage.py runserver --settings={APP_NAME}.settings.dev，我得到的导入错误“没有命名为“设置模块”：

“无模块命名“共同”

我觉得我失去了一些东西简单在这里，但似乎无法弄清楚这里是我的文件的内容：

dev.py：

from django.core.wsgi import get_wsgi_application 

application = get_wsgi_application() 

PG是项目名称;我尝试删除它，并在manage.py和wsgi.py中使用'settings.dev'，但没有运气。

这里有一个类似的线程，但问题似乎有所不同。

如果你要使用你的项目是什么，我建议你尝试做不同的设置模块是在wsgi.py文件中添加了“DJANGO_SETTINGS_MODULE”。之前和之后，我都遇到过这样的问题，因为它正常工作。我希望这能解决你的问题。

sys.path.append('/path/to/project) 
os.environ["DJANGO_SETTINGS_MODULE"] = 'your_settings_module'
