Flask, ImportError: No module named XXX

Question

第一个flask项目，做一个简单的网址导航。部署项目后，浏览器访问报500错误。查看apache日志后，报错如下： [Tue Jan 06 09:58:22 2015] [error] hello world [Tue Jan 06 09:58:22 2015] [error] [client 112.64.71.131] mod_wsgi (pid=31615): Target WSGI script '/var/www/qianshan/qianshan.wsgi' cannot be loaded as Python module.

Answer 1

将第四行修改为：
from qianshan import extras
