WSGI脚本无法作为Python模块加载 - 500内部服务器错误

标签： python django apache amazon-web-services amazon-ec2

根据我的错误日志，我的目标WSGI脚本无法作为Python模块加载，但在我的日志结束时，我还得到一个 ImportError：没有名为foodshop.settings 的模块。我可以验证该模块是否存在。

这是我的错误日志：

最后，这是我的wsgi.py文件：

import os

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

from django.core.wsgi import get_wsgi_application

application = get_wsgi_application()

我已经连接到EC2实例（Ubuntu 14.04），而且我在这个实例上只运行了1个应用程序。当我在本地主机上运行它时，它运行正常。

您没有做任何事情将您的应用及其设置文件放在Python路径上。

如果您没有使用virtualenv（尽管您应该这样做），最简单的方法是在您的wsgi文件中执行：

import os, sys
sys.path.append('/home/ubuntu/gather/src')
os.environ.setdefault("DJANGO_SETTINGS_MODULE", "foodshop.settings")
