python - 配置 Django

Question

我刚刚在 OS X 10.8 和 python 2.7 上安装了 Django 1.6，但在学习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

然后我进入我的站点并运行

python manage.py runserver

得到这个错误:

Traceback (most recent call last):

  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直到结束:

文件“/System/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/functools.py”，第 56 行，在 '_lt_': [('_gt_', lambda self, other: other < self),

这是最后几行输出:

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

  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

看了最后一行之后:

RuntimeError: maximum recursion depth exceeded while calling a Python object

我也跑了:

django-admin.py check

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.

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

这是我的设置.py:

"""

 mysite/
  __init__.py
  settings.py
  urls.py
  __init__.pyc
  settings.pyc
  wsgi.py

我是 django 的新手，真的被困住了。谁能提供一些见解？

Answer 1

检查 manage.py 如果你有这个:

import os

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

在 wsgi.py 中:

import os

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

此外，任何集成 Django 的 python 脚本都应该如下所示:

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