我刚刚将我的 Rails 应用程序推送到 Heroku。然后我运行 heroku db:migrate 然后 heroku db:push。但是当我打开应用程序时，我收到错误消息“应用程序发生错误，无法提供您的页面。请稍后再试。如果您是应用程序所有者，请查看您的日志以获取详细信息”。

所以我运行了heroku日志，这就是我得到的：

我几乎无法理解这里的这些文件。有什么我可能做错了吗？我正在使用 Rails 3.2，并且我已经确定我使用了 heroku --stack cedar，因为我在某处读到 heroku 仅支持 cedar 堆栈上的 Rails 3。

--UPDATE-- 根据 Leo Correa 的要求，下面是我的 users_controller.rb 的片段

def signed_in_user
     unless signed_in?
        store_location
        redirect_to (signin_url, notice: t("user.please")) 
     end
    end

这似乎是一个语法错误，您可能会遗漏大括号或括号之类的内容

/app/app/controllers/users_controller.rb:54: syntax error, unexpected tSTRING_BEG, expecting keyword_do or '{' or '(' (SyntaxError)
2013-05-10T17:13:21.460325+00:00 app[web.1]:         redirect_to signin_url, notice: t "user.please"

那个大块给了它。因此，在第 54 行的 users_controller 中的某处。尝试这样做

redirect_to(signing_url, notice: t('user.please'))

我认为这是您需要添加的资产预编译config.assets.initialize_on_precompile = false问题config/application.rb。如果添加在config/environments/production.rb

从您的日志看来，语法错误如下：

redirect_to(signing_url, notice: t('user.please'))

我认为您正在使用Devise Gem检查您的代码。

您可能会使用 heroku 的免费帐户。当您使用 heroku 的免费帐户时，您每天只能使用 18 小时，然后自动进入睡眠状态或筋疲力尽。发生这种情况时，您将收到此错误页面。如果您的网站繁忙，请尝试将帐户跳过为爱好类型。
