Django应用配置不正确-应用模块具有多个文件系统位置 [英] Django App Improperly Configured - The app module has multiple filesystem locations
问题描述
我认为我确实搞砸了。在我的django应用程序(生产版本)上,我推送了一个重大更新,并且每当尝试访问域时都会收到内部服务器错误消息。我的uwsgi日志中出现错误:
I think I've really screwed something up. On my django app (the production one) I pushed a major update and am get an "Internal Server Error" whenever I try to go to my domain. I am getting an error in my uwsgi logs:

我不知道发生了什么事: app模块< module'ledger'(namespace)>具有多个文件系统位置(['./ledger'、'/home/ubuntu/web/app/ledger']);您必须使用带有 path类属性的AppConfig子类来配置此应用。
。
I have no idea what is going on: 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.
.
这是我的settings.py文件:

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。
Lastly, when I try to checkout a previous version of the code. I get the same problems.
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是uwsgi的错,因为我只更新了Django项目。
I don't know why the problem would be uwsgi's fault as I only updated the Django project.
推荐答案
我删除了 __ init __。py
文件。显然,django使用它们来了解哪些文件夹是 apps ,因此它们很重要。
The problem was that I deleted an __init__.py
file. Apparently, django uses them to know which folders are apps, so they are kind of important.
