[Django+Apache] ImportError: Could not import settings 'xxx.settings' (Is it on sys.path?):

這裏主要是wsgi找不到settings.py的路徑所導致的。
我們需要修改wsgi.py

import os
import sys
root_path = os.path.abspath(os.path.join(os.path.dirname(__file__), '..'))
sys.path.insert(0, root_path)

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

# This application object is used by any WSGI server configured to use this
# file. This includes Django's development server, if the WSGI_APPLICATION
# setting points here.
from django.core.wsgi import get_wsgi_application
application = get_wsgi_application()

# Apply WSGI middleware here.
# from helloworld.wsgi import HelloWorldApplication
# application = HelloWorldApplication(application)

將我們的path加入系統環境變量。
