Rails + Heroku：我们很抱歉，但出了点问题

嗨，这是我第一次尝试将项目推送到Heroku，我收到错误： We're sorry, but something went wrong. 我不知道如何阅读heroku日志。 这是弃用警告吗？ 我的供应商/插件中没有任何东西……有人可以帮我弄清楚什么是错的吗？ 如果您需要任何其他文件，请告诉我。

Answer 1

谷歌与WARN: tilt autoloading 'sass' in a non thread-safe way; explicit require 'sass' suggested. WARN: tilt autoloading 'sass' in a non thread-safe way; explicit require 'sass' suggested.

我找到了这个答案： https ： //stackoverflow.com/a/12859696/1008230
看起来资产需要在本地编译。

这里有一些参考：

对于更快的资产预编译，您可以通过在config / application.rb中将config.assets.initialize_on_precompile设置为false来部分加载应用程序，但在这种情况下，模板无法查看应用程序对象或方法。 Heroku要求这是假的。

http://guides.rubyonrails.org/asset_pipeline.html#precompiling-assets

在预编译资产时，在Rails 3.1.1及更高版本中，您可以通过确保config / application.rb中包含以下行来阻止初始化应用程序并连接到数据库： config.assets.initialize_on_precompile = false

https://devcenter.heroku.com/articles/rails3x-asset-pipeline-cedar#troubleshooting

没有自己尝试，希望有所帮助。

Answer 2

首先，几个指针。 消息We're sorry, but something went wrong是Heroku在应用程序中出现任何错误时向最终用户提供的内容，因为您处于生产模式。 这与您在本地计算机上的开发模式中发生的情况不同，理论上您不希望将调试堆栈跟踪公开给出现的应用程序的任何用户。

弃用警告是红鲱鱼; 它是关于Heroku注入每个Rails应用程序的一些gem，与它们的日志管理内容集成。

错误日志中真正相关的行就是这一行：

 2012-10-23T20:29:56+00:00 app[web.1]: ActionView::Template::Error (/app/app/assets/stylesheets/application.css has already been required): 

在样式表的处理方式中，这可能是一个错误，可能在资产管道function中。 这就是@ evanc3询问你有多少样式表的原因。 而且，我承认，我不知道如何调试这个问题 – 所以这只是一个部分答案。 希望我能让你走上正确的道路。
