Django没有名为“main”的模块

Question

我在我的电脑上做一个Django项目，然后我创建了一个名为“register”的应用程序，当我试图运行manage时，我遇到了一个奇怪的错误。py runserver:im使用Python 3.8.3。当我添加表单进行注册时，会发生此错误。

  File "manage.py", line 21, in <module>
    main()
  File "manage.py", line 17, in main    
    execute_from_command_line(sys.argv)
  File "C:\Python38\lib\site-packages\django\core\management\__init__.py", line 401, in execute_from_command_line
    utility.execute()
  File "C:\Python38\lib\site-packages\django\core\management\__init__.py", line 377, in execute
    django.setup()
  File "C:\Python38\lib\site-packages\django\__init__.py", line 24, in setup
    apps.populate(settings.INSTALLED_APPS)
  File "C:\Python38\lib\site-packages\django\apps\registry.py", line 91, in populate
    app_config = AppConfig.create(entry)
  File "C:\Python38\lib\site-packages\django\apps\config.py", line 116, in create
    mod = import_module(mod_path)
  File "C:\Python38\lib\importlib\__init__.py", line 127, in import_module
    return _bootstrap._gcd_import(name[level:], package, level)
  File "<frozen importlib._bootstrap>", line 1014, in _gcd_import
  File "<frozen importlib._bootstrap>", line 991, in _find_and_load
  File "<frozen importlib._bootstrap>", line 961, in _find_and_load_unlocked
  File "<frozen importlib._bootstrap>", line 219, in _call_with_frames_removed
  File "<frozen importlib._bootstrap>", line 1014, in _gcd_import
  File "<frozen importlib._bootstrap>", line 991, in _find_and_load
  File "<frozen importlib._bootstrap>", line 973, in _find_and_load_unlocked
ModuleNotFoundError: No module named 'main'

我的设置。py:

DEBUG = True


ALLOWED_HOSTS = ['*']

SETTINGS_PATH = os.path.dirname(os.path.dirname(__file__))
# Application definition

INSTALLED_APPS = [
    'django.contrib.admin',
    'django.contrib.auth',
    'django.contrib.contenttypes',
    'django.contrib.sessions',
    'django.contrib.messages',
    'django.contrib.staticfiles',
    'simple2',
    "crispy_forms",
    'main.apps.MainConfig',
    'register.apps.RegisterConfig',
    'register'
]
...

我猜想您没有配置WSGI应用程序，因为Django的应用程序引擎在名为main的文件中查找一个html" target="_blank">变量。py。这里有两种方法可以让你看到这一点：

包括WSGI应用程序

您仍然可以创建名为main的文件。py，包括一个app变量。您不需要编写任何东西，只需导入它（假设您的项目名称是projekt）：

from projekt.wsgi import main as app

添加自定义入口点

与Google的AppEngine一样：

入口点：可选。应用程序启动时执行的命令。要使应用程序接收HTTP请求，入口点应包含一个命令，该命令启动web服务器，该服务器侦听端口环境变量指定的端口。如果您没有指定入口点，App Engine将配置并启动Gunicorn Web服务器。

默认值和您的需要之间的比较：

# default
entrypoint: gunicorn -b :$PORT main:app
# What you need
entrypoint: gunicorn -b :$PORT demosite.wsgi:main
