提问by theNinja

I just installed Django 1.6 on OS X 10.8 with python 2.7 and am having trouble going through the tutorial. After setting creating a server called mysite by running:

我刚刚使用 python 2.7 在 OS X 10.8 上安装了 Django 1.6，但在阅读本教程时遇到了问题。通过运行设置创建名为 mysite 的服务器后：

django-admin.py startproject mysite

I then cd'ed into mysite and ran

然后我 cd 进入 mysite 并运行

python manage.py runserver

and got this error:

并收到此错误：

this error ends up being repeatedly printed until the end:

这个错误最终会被重复打印，直到结束：

File "/System/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/functools.py", line 56, in '_lt_': [('_gt_', lambda self, other: other < self),

文件“/System/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/functools.py”，第 56 行，'_ lt_'：[('_ gt_', lambda self, other : 其他 < 自己),

And here are the last few lines of output:

这是输出的最后几行：

  File "/System/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/functools.py", line 56, in <lambda>

    '__lt__': [('__gt__', lambda self, other: other < self),
RuntimeError: maximum recursion depth exceeded while calling a Python object

After looking at the last line:

查看最后一行后：

RuntimeError: maximum recursion depth exceeded while calling a Python object

I also ran:

我也跑了：

django-admin.py check

and got this output:

并得到这个输出：

django.core.exceptions.ImproperlyConfigured: Requested setting DEFAULT_INDEX_TABLESPACE, but settings are not configured. You must either define the environment variable DJANGO_SETTINGS_MODULE or call settings.configure() before accessing settings.

I also tried setting my environment variable in tcsh by typing in:

我还尝试通过键入以下内容在 tcsh 中设置我的环境变量：

setenv DJANGO_SETTINGS_MODULE "mysite.settings"

but it still gave me the recursion depth error. Running

但它仍然给了我递归深度错误。跑步

django-admin.py check

then gave me this error:

然后给了我这个错误：

我是 Django 的新手，我真的被困住了。任何人都可以提供一些见解吗？

Ok so I finally found the answer. Apparently the error was a result of Python 2.7.2. Once I upgraded to 2.7.6, the problem went away.

好的，所以我终于找到了答案。显然该错误是 Python 2.7.2 的结果。一旦我升级到 2.7.6，问题就消失了。

Here is a similar thread where I found the answer:

这是我找到答案的类似线程：

maximum recursion depth exceeded in cmp error while executing python manage.py runserver

执行 python manage.py runserver 时 cmp 错误中超出了最大递归深度

Don't know why this solution didn't show up in my searches when I was creating this thread...

不知道为什么当我创建这个线程时这个解决方案没有出现在我的搜索中......

Check in manage.pyif you have this:

manage.py如果你有这个，请检查：

import os

if __name__ == "__main__":
    os.environ.setdefault("DJANGO_SETTINGS_MODULE", "mysite.settings")

And in wsgi.pythis:

而在wsgi.py这方面：

import os

os.environ.setdefault("DJANGO_SETTINGS_MODULE", "mysite.settings")

Also, any python scripts that integrate Django should look like this:

此外，任何集成 Django 的 Python 脚本都应如下所示：

import os
os.environ.setdefault("DJANGO_SETTINGS_MODULE", "mysite.settings")
# Uncomment below for Django 1.7 +
#import django
#django.setup()
