Ruby on rails RubyonRails教程Michael Hartl第2章练习（演示应用程序）：应用程序可以在Windows 8 localhost上运行，但不能'；我不在Heroku工作

我是网络开发新手，我正在努力学习RoR。我的问题在第二章（demo_应用程序，一个类似使用脚手架的微博）

demo_应用程序在localhost:3000上运行良好，但当我将其推送到Heroku时，它不起作用（索引和/users或/microscops），并显示以下消息：

*“应用程序错误 应用程序中出现错误，无法提供您的页面。请稍后再试

如果您是应用程序所有者，请查看日志以了解详细信息。”*

这是Heroku的日志：

以下是存储库：

我也试过：

bundle exec rake assets:precompile
git add .
git commit -am "add a note reflecting changes made"
git push
heroku create
git push heroku master
heroku rake db:migrate
heroku db:push

（最终，我的本地应用程序实现了收支平衡，所以我回滚了）

我正在使用Windows 8并安装Railsinstaller

抱歉，如果缺少一些信息，我对这一切还是有点陌生。

错误在这里：

2013-07-18T23:47:29.239184+00:00 heroku[web.1]: Starting process with command `bin/rails server -p 40177 -e $RAILS_ENV`
2013-07-18T23:47:30.141486+00:00 app[web.1]: bash: bin/rails: No such file or directory

尝试向具有以下内容的应用程序添加：

web: bundle exec rails server -p $PORT

---

我运行了

web:bundle-exec-rails-server-p$PORT

但得到了一个错误
