0運行蟒蛇manage.py runserver命令的virtualenv激活時

我檢查一切，地平線應用程序是在settings.py

這個Django項目工作正常。

Apache沒有解決您的虛擬環境問題。檢查你的錯誤跟蹤的第一行

/usr/lib/python2.7/dist-packages/django/core/handlers/base.py 

它指向默認的python位置不是你的虛擬env。 試試這個包含虛擬env路徑。

sys.path.append('/var/www/projects/openstack-horizon/.venv/local/lib/python2.7/site-packages')
