Dreamhost 中的 500 个错误 运行 Passenger 下的 Django
500 Errors in Dreamhost Running Django under Passenger
还是一首悲伤的老歌，但有新的信息！
我是 运行 Django 1.8.3，Python 2.7.3 作为 Pythonbrew 安装在共享 Dreamhost 服务器上；通常，在 "python manage.py address.org:8080" 下一切正常，但当直接导航到站点时无法正常工作，给出通用的 500 内部服务器错误，并且错误日志给出 header 消息的过早结束.
但是，我将“粘贴”粘贴到那里，以实际得到从跟踪中踢回的错误。

我的passenger_wsgi.py就是这样格式化的
import sys, os
INTERP = "/home/syslib/.pythonbrew/pythons/Python-2.7.3/bin/python"
#INTERP is present twice so that the new python interpreter knows the actual executable path
if sys.executable != INTERP: os.execl(INTERP, INTERP, *sys.argv)
sys.path.insert(0, os.getcwd(), "staff_site")
os.environ['DJANGO_SETTINGS_MODULE'] = "staff_site.settings"
from paste.exceptions.errormiddleware import ErrorMiddleware
import django.core.handlers.wsgi
DjangoApp = django.core.handlers.wsgi.WSGIHandler()
application = ErrorMiddleware(DjangoApp, debug=True)
编辑：中断下方的原始答案没有完全解决问题。不过，它确实起到了临时补丁的作用，并为我指出了正确的答案。
实际的、功能齐全的 Django 1.8.3 passenger_wsgi.py 应该大致如下所示，假设 Python 的正常 virtualenv 安装冻结资产：
import sys, os
INTERP = "/home/<username>/<domain>/public/env/bin/python"
if sys.executable != INTERP: os.execl(INTERP, INTERP, *sys.argv)
sys.path.insert(0, os.getcwd()+"public/<your_app_name>/")
os.environ['DJANGO_SETTINGS_MODULE'] = "<your_app_name>.settings"
from django.core.wsgi import get_wsgi_application
application = get_wsgi_application()
好的，所以我找到了解决方法。按照 Joran 在评论中的提示，我查看了 settings.py 并发现了
WSGI_APPLICATION = 'staff_site.wsgi.application'
并意识到 Passenger 没有加载它。阅读 Django 1.8.3 上的文档，我看到它生成了它自己的 WSGI 兼容应用程序，并且回溯似乎无法实际获得可用的应用程序。首先我试着把
application = ErrorMiddleware(WSGI_APPLICATION, debug=True)
但是失败了，Passenger 给出了 WSGI_APPLICATION 未定义的错误。因此，我尝试了一种不同的方法。现在这是我的 passenger_wsgi.py 文件，但我的信息被删除了。我保留了粘贴代码，以绕过 Django/Passenger 关于生成有用错误的分歧。如果 Dreamhost 上的任何人遇到 Django 1.8.3 的 500 错误问题，这似乎有效：
import sys, os
INTERP = "/home/path/to/your/install/of/python"
#INTERP is present twice so that the new python interpreter knows the actual executable path
if sys.executable != INTERP: os.execl(INTERP, INTERP, *sys.argv)
sys.path.insert(0, os.getcwd()+"<your_app_name>")
os.environ['DJANGO_SETTINGS_MODULE'] = "<your_app_name>.settings"
from paste.exceptions.errormiddleware import ErrorMiddleware
import django.core.handlers.wsgi
from <your_app>.wsgi import application as DjangoApp
