问题描述
我是网络开发新手，我正在尝试通过 Michael Hartl的书Ruby on Rails教程。我的问题在第二章（demo_app，类似微博的使用脚手架）。
demo_app在localhost：3000上完美运行，但是当我将它推送到Heroku时，它不起作用（索引和/用户或/ microposts）并显示消息：
*应用程序错误
应用程序发生错误，您的页面无法投放，请稍后重试。 p>
如果您是应用程序所有者，请查看日志以了解详细信息。*
以下是Heroku的日志： p>

以下是存储库： https://github.com / sergioschuler / demo_app
我也试过：
bundle exec rake资源：预编译
git add。
git commit -am添加注释反映所做的更改
git push
heroku创建
git push heroku master
heroku rake db：迁移
heroku db：push
（最终我破解了我的本地应用程序，所以我回滚了）
我使用Windows 8并使用Railsinstaller进行安装。
对不起，如果缺少一些信息，我仍然有点新所有这些。

I am new to web development and I am trying to learn RoR with Michael Hartl's book Ruby on Rails Tutorial. My problem is on Chapter 2 (the demo_app, a microblog-like using scaffolding).
The demo_app runs perfectly on localhost:3000, but when I push it to Heroku, it doesn't work (both the index and /users or /microposts) and shows the message:
*"Application Error An error occurred in the application and your page could not be served. Please try again in a few moments.
If you are the application owner, check your logs for details."*

Here is the repository: https://github.com/sergioschuler/demo_app
I tried this too:
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
(Eventually I broke even my local app, so I rolled back)
I am using Windows 8 and installed with Railsinstaller.
Sorry if there is some info missing, I am still a bit new to all this.
解决方案
The error is here:
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
Try adding a Procfile to your application that has this:
web: bundle exec rails server -p $PORT
这篇关于Ruby on Rails教程Michael Hartl第2章练习（demo_app）：应用程序在Windows 8 localhost上工作，但在Heroku上不起作用的文章就介绍到这了，希望我们推荐的答案对大家有所帮助，也希望大家多多支持IT屋！
