在heroku部署django项目提示Application error怎么办？

Question

我的电脑是win7-64位的，根据《Python编程 从入门到实践》，我尝试学习了Django。

在虚拟环境下要把在django项目部署到heroku，但是heroku open打开网页后，提示Application error

An error occurred in the application and your page could not be served. If you are the application owner, check your logs for details. You can do this from the Heroku CLI with the command heroku logs --tail

我百度搜索了这个问题，依然没找到解决办法。

heroku logs --tail查看问题如下：
