python - 在 django 中导入设置时出现奇怪的错误

Question

我有很多项目在 ubuntu 中使用 python2.7 和 virtualenv/virtualenvwrapper，在我的工作中一些开发人员使用 macosx 和 windows，通常我像往常一样创建项目:

django-admin.py start project x

我们将 svn 用于 cvs，但在某些时候，当我尝试类似的操作时，对我来说没有任何理性:

python manage.py runserver

不起作用，但仅供我使用并且在我的笔记本电脑中，这不会发生在生产服务器或其他开发人员中。

有什么想法吗？

我遇到了这个错误:

Error: Can't find the file 'settings.py' in the directory containing 'manage.py'. It appears you've customized things. You'll have to run django-admin.py, passing it your settings module. (If the file settings.py does indeed exist, it's causing an ImportError somehow.)

但很明显，设置文件存在并且与 manage.py 文件位于同一文件夹中，并且不适用于我...

django and appengine 也会发生这种情况

I got this error:

Error: Can't find the file 'settings.py' in the directory containing 'manage.py'. It appears you've customized things. You'll have to run django-admin.py, passing it your settings module. (If the file settings.py does indeed exist, it's causing an ImportError somehow.)

每当发生导入错误时，manage.py 脚本都会打印该警告，因此，如果您的 settings.py 模块导入内容并且那导致导入错误，manage.py 仍会打印该警告。

一种诊断方法是(暂时)将 manage.py 从

#!/usr/bin/env python
from django.core.management import execute_manager
try:
    import settings # Assumed to be in the same directory.
except ImportError:
    import sys
    sys.stderr.write("Error: Can't find the file 'settings.py' in the directory containing %r. It appears you've customized things.\nYou'll have to run django-admin.py, passing it your settings module.\n(If the file settings.py does indeed exist, it's causing an ImportError somehow.)\n" % __file__)
    sys.exit(1)

if __name__ == "__main__":
    execute_manager(settings)

到

#!/usr/bin/env python
from django.core.management import execute_manager
import settings # Assumed to be in the same directory.

if __name__ == "__main__":
    execute_manager(settings)

并查看运行 $ python manage.py runserver 时打印的堆栈跟踪。
