我一直试图弄清楚日志中出了什么问题，但不知道如何修复它。以下是日志中的片段我对如何修复感到有些困惑。任何帮助将不胜感激。
Could not load SystemTimer >= v1.2.0. Falling back to timeout.rb. SystemTimer is STRONGLY recommended for timeouts in Ruby 1.8.7. See http://ph7spot.com/blog/system-timer-1-2-release for details.

我有同样的事情。在开发过程中，一个规范以某种方式被复制到控制器文件夹中。在当地没有任何影响，但坠毁了雪松...
答案 1 :(得分：0)
我认为问题可能出在这一行：
/app/.bundle/gems/ruby/1.8/gems/activesupport-3.1.0/lib/active_support/dependencies.rb:306:in `depend_on': No such file to load -- spec_helper (LoadError)
似乎你的一个初始化程序中有require "spec_helper"（或者在其他地方加载一个文件，但不应该这样做）。这可能与Gemfile中:test组中的宝石有关，这些宝石默认情况下不会在Heroku上加载。
您可以尝试在本地运行bundle install --without test development以重现Heroku如何安装宝石。请注意，这将是bundle在您从项目中删除./.bundle/config文件之前安装gem的永久方式，因此一旦您解决了问题，您将希望这样做。
希望这会有所帮助......
答案 2 :(得分：-1)
与乘客有同样的问题。问题是依赖于lib的模型中的需求。将lib目录添加到自动加载并删除所有需要（由fgrep 'require' -r app/找到）。
