Question

我试图按this guide为Django应用设置模块。

我创建了设置模块，其中包含 __ init __ .py，common.py和dev.py.但是，当我尝试python manage.py runserver --settings=settings.dev时，我收到导入错误：

＆＃34;没有名为＆＃39;设置的模块＆＃34;

如果我尝试python manage.py runserver --settings={APP_NAME}.settings.dev，则会收到导入错误：

＆＃34;没有名为＆＃39; common＆＃39;

的模块

我觉得我在这里错过了一些简单的东西，但似乎无法弄明白。以下是我的文件内容：

dev.py：

# from os.path import join, normpath

    }

wsgi.py

import os

root_path = os.path.abspath(os.path.split(__file__)[0])
sys.path.insert(0, os.path.join(root_path, 'PG.settings.dev'))
sys.path.insert(0, root_path)

os.environ.setdefault("DJANGO_SETTINGS_MODULE", "PG.settings.dev")

from django.core.wsgi import get_wsgi_application

application = get_wsgi_application()

PG是项目的名称;我试过删除它并使用＆quot; settings.dev＆＃39;在manage.py和wsgi.py中，但没有运气。

这里有一个类似的主题，但问题似乎有所不同。

如果您尝试为项目使用不同的设置模块，我建议您尝试添加＆＃34; DJANGO_SETTINGS_MODULE＆＃34;在你的wsgi.py文件中。在这样做之前和之后我遇到了这个问题它正常工作。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'

Django无法识别设置模块
