Heroku "We're sorry, but something went wrong." due to javascript_include_tag
提问by Karan
Uploading my ruby on rails app to heroku causes the following error:
将我的 ruby on rails 应用程序上传到 heroku 会导致以下错误：
We're sorry, but something went wrong.
我们很抱歉，但有些不对劲。
This does not occur on my local machine.
这不会发生在我的本地机器上。
After some debugging, I think I may have spotted the error, but do not know how to fix it.
经过一些调试，我想我可能已经发现了错误，但不知道如何修复它。
In my file application.html.erb, removing the following line solves the problem, but then my app loses its jquery mobile theme. Any ideas what I could do to fix the problem?
在我的文件 application.html.erb 中，删除以下行解决了问题，但随后我的应用程序丢失了它的 jquery 移动主题。有什么想法可以解决问题吗？

<%= javascript_include_tag "application" %>

Problem solved!
问题解决了！
It was simple - taken from 500 internal server error when I try to push my app onto Heroku
这很简单 -当我尝试将我的应用程序推送到 Heroku 时，取自500 个内部服务器错误
So based upon the heroku info that you provided I see that you are on the bamboo stack and that stack does not support Rails 3.1+. Only the cedar stack supports Rails 3.1+. You'll need to use the following command to create a new app on the cedar stack:
heroku create --stack cedar
因此，根据您提供的 heroku 信息，我看到您在竹栈上，并且该栈不支持 Rails 3.1+。只有 cedar 堆栈支持 Rails 3.1+。您需要使用以下命令在 cedar 堆栈上创建一个新应用程序：
heroku 创建 --stack 雪松

In config/application.rb, add
在 config/application.rb 中，添加
config.assets.initialize_on_precompile = false
and push to git, then heroku push.
并推送到 git，然后是 heroku 推送。

Are you also setting
你也在设置
config.assets.initialize_on_precompile = false
This is a new change on Rails 3.2 (see the Docs)
这是 Rails 3.2 的新变化（参见文档）
Nevertheless, you should be able to see an error during the slug compilation (as example below, if you do not set the above flag)
尽管如此，您应该能够在 slug 编译期间看到错误（如下例，如果您没有设置上述标志）
-----> Preparing app for Rails asset pipeline
Running: rake assets:precompile
rake aborted!
could not connect to server: Connection refused
Is the server running on host "127.0.0.1" and accepting
TCP/IP connections on port 5432?
You can also try to run the rake precompile task locally, and see the error (again, as the documentation is suggesting).
您也可以尝试在本地运行 rake 预编译任务，并查看错误（再次，正如文档所建议的那样）。

make sure there are no untracked files, do git status
