无法在Django部署时导入模块

Question

我正在尝试在我的服务器上部署一个Django项目，我正在部署激活了virtualenv的Django。

下面是我从apache2日志中得到的错误

这是我的虚拟主机

<VirtualHost *:8060>
        ServerAdmin jonathan.c@advitor.com
        ServerName automation-cloud.com
        ServerAlias www.automation-cloud.com
        WSGIScriptAlias / var/www/projects/openstack-horizon/horizon.wsgi

        Alias /static/ /var/www/projects/openstack-horizon/openstack_dashboard/static/
        <Location "/static/">
            Options -Indexes
        </Location>
</VirtualHost>

这是我的horizon.wsgi文件

import os
import sys
import site

# Add the site-packages of the chosen virtualenv to work with
site.addsitedir('/var/www/projects/openstack-horizon/.venv/local/lib/python2.7/site-packages')

# Add the app's directory to the PYTHONPATH
sys.path.append('/var/www/projects/openstack-horizon')
#sys.path.append('/var/www/projects/openstack-horizon/horizon')
sys.path.append('/var/www/projects/openstack-horizon/openstack_dashboard')
#/usr/lib/python2.7/dist-packages/horizon/
sys.path.append('/usr/lib/python2.7/dist-packages/horizon')
os.environ['DJANGO_SETTINGS_MODULE'] = 'openstack_dashboard.settings'

# Activate your virtual env
activate_env=os.path.expanduser("/var/www/projects/openstack-horizon/.venv/bin/activate_this.py")
execfile(activate_env, dict(__file__=activate_env))

import django.core.handlers.wsgi
application = django.core.handlers.wsgi.WSGIHandler()

我检查了所有东西，地平线应用程序在settings.py上

这个Django项目在运行python manage.py runserver virtualenv activated时运行良好。

Apache不是针对您的虚拟环境的。检查错误跟踪的第一行

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

它指向默认的python位置，而不是您的虚拟环境。尝试此操作以包含虚拟环境路径。

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