Django:使用Django-admin.py导入错误

目前，我在/Users/hobbes3/Sites/中为Django创建了两个符号链接。ls-l显示以下内容

lrwxr-xr-x   1 hobbes3  staff    66B Feb 23 04:16 django -> /usr/local/Cellar/python/2.7.2/lib/python2.7/site-packages/django/
lrwxr-xr-x   1 hobbes3  staff    85B Feb 23 01:01 django-admin.py -> /usr/local/Cellar/python/2.7.2/lib/python2.7/site-packages/django/bin/django-admin.py
drwxr-xr-x  15 hobbes3  staff   510B Feb 24 16:04 mysite/

其中mysite/是我根据官方民意测验教程构建的唯一Django项目

当我键入python django-admin.py时，一切正常

hobbes3@hobbes3:~/Sites$ python django-admin.py
Usage: django-admin.py subcommand [options] [args]

Options:
  -v VERBOSITY, --verbosity=VERBOSITY
                        Verbosity level; 0=minimal output, 1=normal output,
                        2=all output
  --settings=SETTINGS   The Python path to a settings module, e.g.
                        "myproject.settings.main". If this isn't provided, the
                        DJANGO_SETTINGS_MODULE environment variable will be
                        used.
  --pythonpath=PYTHONPATH
                        A directory to add to the Python path, e.g.
                        "/home/djangoprojects/myproject".
  --traceback           Print traceback on exception
  --version             show program's version number and exit
  -h, --help            show this help message and exit

Type 'django-admin.py help <subcommand>' for help on a specific subcommand.

Available subcommands:
  cleanup

我注意到我可以使用Pythondjango-admin.py startproject asd很好地启动项目

我正在运行Python 2.7.2和Django 1.3.1。

Django-admin.py正在查找您的settings.py文件，该文件应位于/Users/hobbes3/Sites/mysite中

如果您将cd刻录到~/Sites/mysite，然后运行django-admin.py inspectdb doors-eer，这样应该可以正常工作

这假设您在settings.py中设置了数据库变量

---

此外，在创建项目后，使用Django的更传统方法是在创建项目后调用manage.py inspectdb。通过调用django-admin.py，环境变量无法正确设置，django无法找到您的settings.py文件。

Ok，因此我将cd mysite放在光盘上，然后运行python../django-admin.py inspectdb door eer，它仍然会给我同样的错误。我打开了settings.py，验证了我的数据库变量设置正确……在切换到/mysite目录后，运行python manage.py inspectdb，不带任何参数。哦，我刚刚意识到你说在mysite中使用manage.py而不是django-admin.py。谢谢你，这对我现在起作用了。现在我只需要创建一个新的临时项目来读取doors eer数据库，然后运行inspectdb。但是在将来，如何修复django-admin.py命令？当您使用python创建项目时，django-admin.py startproject myproject django将创建一个名为“myproject”的目录，并将预先填充该目录，其中包含开始使用django时所需的所有文件：settings.py manage.py url.pyOk，因此我将cd mysite，然后运行python../django-admin.py检查DB门eer，它仍然给我同样的错误。我打开了settings.py，验证了我的数据库变量设置正确……在切换到/mysite目录后，运行python manage.py inspectdb，不带任何参数。哦，我刚刚意识到你说在mysite中使用manage.py而不是django-admin.py。谢谢你，这对我现在起作用了。现在我只需要创建一个新的临时项目来读取doors eer数据库，然后运行inspectdb。但是在将来，如何修复django-admin.py命令？当您使用python创建项目时，django-admin.py startproject myproject将创建一个名为“myproject”的目录，并将使用开始使用django:settings.py manage.py url.py所需的所有文件预填充该目录
