Django：无法导入设置

我运行了以下命令：

python manage.py runserver 0.0.0.0:8000

得到错误：

Traceback (most recent call last):
  File "manage.py", line 11, in <module>
    execute_from_command_line(sys.argv)
  File "/usr/lib/python2.6/site-packages/django/core/management/__init__.py", line 399, in    execute_from_command_line
    utility.execute()

    self._setup(name)
  File "/usr/lib/python2.6/site-packages/django/conf/__init__.py", line 49, in _setup
    self._wrapped = Settings(settings_module)
  File "/usr/lib/python2.6/site-packages/django/conf/__init__.py", line 132, in __init__
% (self.SETTINGS_MODULE, e)
ImportError: Could not import settings 'mysite2.settings.settings_custom' (Is it on sys.path? Is there an import error in the settings file?): No module named mysite2.settings.settings_custom

这是我的manage.py：

#!/usr/bin/env python
import os
import sys

if __name__ == "__main__":
    sys.path.append('/home/ec2-user/mysite2/mysite2/settings/settings_custom')
    os.environ.setdefault("DJANGO_SETTINGS_MODULE", "mysite2.settings.settings_custom")

    from django.core.management import execute_from_command_line

    execute_from_command_line(sys.argv)

这是文件位置：

mysite2

在mysite2中，

• manage.py
• mysite2（一个文件夹）

在mysite2中，

• urls.py
• wsgi.py
• 设置（文件夹）

内部设置

• __init__.py
• __init __。pyc
• settings_custom.py
• settings_default.py

我应该如何将路径导入sys.path？Django的新手，非常感谢。
