Question

我刚刚使用python 2.7在OS X 10.8上安装了Django 1.6，但我在浏览教程时遇到了麻烦。通过运行：

设置创建名为mysite的服务器之后

django-admin.py startproject mysite

然后我进入了mysite并跑了

python manage.py runserver

并收到此错误：

Traceback (most recent call last):
  File "manage.py", line 10, in <module>

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

这个错误最终被重复打印到最后：

文件“/System/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/functools.py”，第56行，in '_ lt _'：[（'_ gt _'，lambda self，other：other＆lt; self），

以下是最后几行输出：

  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),

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

看完最后一行后：

RuntimeError: maximum recursion depth exceeded while calling a Python object

我也跑了：

django-admin.py check

得到了这个输出：

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.

我还尝试通过输入以下内容在tcsh中设置我的环境变量：

setenv DJANGO_SETTINGS_MODULE "mysite.settings"

但它仍然给了我递归深度错误。运行

django-admin.py check

然后给了我这个错误：

ImportError: Could not import settings 'mysite.settings' (Is it on sys.path? Is there an import error in the settings file?): No module named mysite.settings

这是我的settings.py：

"""

我是django的新手，我真的被卡住了。任何人都可以提供一些见解吗？

Answer 1

如果您有manage.py，请办理登机手续：

import os

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

在wsgi.py这个：

import os

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

此外，任何集成Django的python脚本应如下所示：

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

Answer 2

好的，我终于找到了答案。显然，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。

这是一个类似的主题，我找到了答案：

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

当我创建这个帖子时，不知道为什么这个解决方案没有出现在我的搜索中......
