在Raspbian上使用Apache的Flask应用出现内部服务器错误
我可以成功地在本地的5000端口上运行我的flask应用，但当我通过浏览器访问raspberrypi.local时，却出现了500内部服务器错误，使用树莓派的IP地址也是同样的错误。
apache的错误日志显示：

这是我的wsgi文件：
#!/usr/bin/python
Import sys
import logging
logging.basicConfig(stream=sys.stderr)
sys.path.insert(0,"/var/www/Intranet_for_RPi/")
from Intranet_for_RPi import app as application
application.secret_key = 'key-gen-secret'
```
我已经把wsgi文件设置为可执行的。我觉得这可能和我的python版本或者与/etc/apache2/mods-available/wsgi.conf相关的路径有关系。
任何帮助都会非常感谢。

这个错误明显是说，wsgi 脚本找不到 Intranet_for_RPi 这个模块。
检查一下你的路径。你可能需要在 Apache 的配置中添加 WSGIPythonPath：
WSGIPythonPath /var/www/Intranet_for_RPi:/var/www/Intranet_for_RPi/packages:etc
<VirtualHost *:80>
