错误运行 wsgi 应用程序：ModuleNotFoundError

Question

我正在尝试在 pythonanywhere 上托管我的本地网络应用程序。 [Django 和网络开发初学者]

我在启动应用程序时遇到以下错误：

Error running WSGI application
2021-04-26 21:46:32,020: ModuleNotFoundError: No module named 'myapp'
2021-04-26 21:46:32,020:   File "/var/www/username_pythonanywhere_com_wsgi.py", line 16, in <module>
2021-04-26 21:46:32,020:     application = get_wsgi_application()
2021-04-26 21:46:32,020: 
2021-04-26 21:46:32,020:   File "/home/username/.virtualenvs/web-virtualenv/lib/python3.8/site-packages/django/core/wsgi.py", line 12, in get_wsgi_application
2021-04-26 21:46:32,020:     django.setup(set_prefix=False)

2021-04-26 21:46:32,021:     self._setup(name)

2021-04-26 21:46:32,021:   File "/home/username/.virtualenvs/web-virtualenv/lib/python3.8/site-packages/django/conf/__init__.py", line 69, in _setup

2021-04-26 21:46:32,021:     mod = importlib.import_module(self.SETTINGS_MODULE)

文件位置：

settings.py 文件位于：

/home/username/WebDev/Website/Django/MyApp/myapp/myapp

我已将“/var/www/username_pythonanywhere_com_wsgi.py”文件修改为：

"""
WSGI config for myapp project.

It exposes the WSGI callable as a module-level variable named ``application``.

For more information on this file, see
https://docs.djangoproject.com/en/3.2/howto/deployment/wsgi/
"""

import os
import sys
sys.path.append("/home/username/WebDev/Website/Django/MyApp/myapp")

os.environ('DJANGO_SETTINGS_MODULE', 'myapp.settings')

from django.core.wsgi import get_wsgi_application
application = get_wsgi_application()

我在 Whosebug 上看过类似的问题，但仍然无法弄清楚我到底出了什么问题。

任何pointers/help将不胜感激。

Answer 1

从外观上看，文件夹结构似乎没问题。

您可能需要做的是将模块添加到您的 INSTALLED_APPS 设置中。

或者，如果您认为已安装的东西出现导入错误或模块未找到错误，那么您可能已将其安装到 Python 或 virtualenv 的版本中，您的代码不在运行中。如果未找到它是您代码的一部分，那么您的 Python 路径未设置，因此它无法看到您尝试导入的模块。参见 https://help.pythonanywhere.com/pages/DebuggingImportError/

Answer 2

错误已解决。

问题是 environ 不是一个函数而是一个过程参数，因此，像下面这样使用它是错误的原因。

os.environ('DJANGO_SETTINGS_MODULE', 'myapp.settings')

我将代码更改为：

os.environ['DJANGO_SETTINGS_MODULE'] = 'myapp.settings'

错误已解决。
