当我尝试将我的应用程序推送到 Heroku 时出现 500 内部服务器错误

【问题标题】：500 internal server error when I try to push my app onto Heroku当我尝试将我的应用程序推送到 Heroku 时出现 500 内部服务器错误
【发布时间】：2012-04-06 17:05:49
【问题描述】：

我在将我的应用推送到 Heroku 时遇到了这个问题：

  • 500 内部服务器错误
  • ActionView::Template::Error...application.css 未预编译（请参阅随附的 Heroku 日志）
  • 另外，ActionController::RoutingError（没有路由匹配 [GET] "/assets/rails.png"

我正在使用 Twitter Bootstrap 2.0.1 和 Rails 3.1.1（请参阅下面的 Gemfile）

任何指导将不胜感激！

  • 我不确定这是否更适合网站管理员或服务器故障，但它似乎与编程无关，所以我认为这不是正确的地方。跨度>

【解决方案1】：

因此，根据您提供的heroku info，我看到您在竹堆栈上，并且该堆栈不支持 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：

heroku create --stack cedar

【讨论】：

    【解决方案2】：

    这是您的样式表没有被编译的结果。 Heroku 将尝试运行

    rake assets:precompile

    在部署您的应用之前。如果预编译命令失败，它现在会静默失败。我实际上在 Heroku 上有一个未解决的问题

    https://github.com/heroku/heroku-buildpack-ruby/issues/9

    最可能的原因是 Rakefile 正在尝试加载（或访问）gem。 Heroku buildpacks 尝试在访问 gemset 之前编译样式表，因此任何要求都会失败。避免这种情况的最佳方法是将这些要求包装在您的 Rakefile 中特定于环境的条件中：

    if Rails.env == 'development' || Rails.env == 'test'
  require 'somegem1'
  require 'somegem2'

  # whatever code is being used by those gems goes in this block
end

    【讨论】：

    • 我很困惑...你能详细说明一下吗？我在哪里可以找到 rake 文件？还有我用什么代替'somegem1,2'和'#whatever code..'？谢谢...
    • Rakefile 位于您应用的根目录中。如果您能说出内容，我应该可以告诉您这是否是问题
    • 谢谢@bcardarella ！！我在上面添加了 rake 文件的内容......让我知道你的想法。
    • 你能在你的应用上运行“heroku info”并粘贴上面的结果吗？
