我想我真的搞砸了。在我的django应用程序（生产一个）上，我推了一个重大更新，每当我尝试进入我的域时就会出现“内部服务器错误”。我在uwsgi日志中收到错误：

我不知道发生了什么：The app module <module 'ledger' (namespace)> has multiple filesystem locations (['./ledger', '/home/ubuntu/web/app/ledger']); you must configure this app with an AppConfig subclass with a 'path' class attribute.。

最后，当我尝试签出以前版本的代码时。我遇到了同样的问题。
编辑 - 添加uwsgi.conf文件
# file: /etc/init/ppuwsgi.conf
description "uWSGI server for PennyPledge"
start on runlevel [2345]
stop on runlevel [!2345]
respawn
exec /usr/local/bin/uwsgi --home /home/ubuntu/web/app/ --socket /home/ubuntu/web/ppuwsgi.sock --chmod-socket=666 --module=pennypledge.wsgi --pythonpath /home/ubuntu/web/ -H /home/ubuntu/.virtualenvs/pennypledge --logto /home/ubuntu/web/logs/uwsgi.log --chdir=/home/ubuntu/web/app --chmod-socket=666
我不知道为什么问题会是uwsgi的错，因为我只更新了Django项目。
问题是我删除了一个__init__.py文件。显然，django使用它们来了解哪些文件夹是应用程序，因此它们非常重要。
错误发生在你的ledger应用程序中。这是一个自定义应用程序？
从Django源代码，错误来自_path_from_module(app_module)
# Filesystem path to the application directory eg.
# u'/usr/lib/python2.7/dist-packages/django/contrib/admin'. Unicode on
# Python 2 and a str on Python 3.
if not hasattr(self, 'path'):
self.path = self._path_from_module(app_module)
作为快速修复，如果这是您的应用程序，您可以使用具有有效AppConfig属性的path子类来配置它，这将阻止错误执行。我现在正在进一步研究它。
如果ledger不是您的应用程序，并且您已通过pip或其他方式更新它，这就解释了为什么签出旧版本无法解决问题。尝试从其存储库（如果适用）获取该应用程序的旧版本并提交错误报告。
