所以 Heroku 一整天都在停机，当然，直到我对我的应用程序进行了大量更改后，我才意识到这一点。现在 Heroku 已备份，我的应用程序已损坏。

这是一个随机文本块，让 stackoverflow 认为我已经更好地解释了我的代码块，因为他们不会让我发布其他内容。

这是我的heroku日志：

这可能是一个 Ruby 版本问题，因为random = Random.rand(1..4)在我运行 MRI-1.9.3 的系统上运行良好。也许电风暴导致 Heroku 改变了你的 Ruby。也许你依赖于现在已经失效的 1.9.3 实验室插件。

检查您正在运行的版本heroku run ruby -v，您可以通过将以下内容放在 gemfile 的顶部来强制他们使用 1.9.3：

source 'https://rubygems.org'
ruby '1.9.3'

您为 rand 方法使用了错误的参数，它只接受一个整数，而不是它们的范围。

你正在寻找

random = Random.rand(4)

您的另一个选择不是使用 Random，而是使用Array#sample

random = (1..4).to_a.sample

假设您没有向 Heroku 推送任何引入了一些错误代码的新代码。

我会检查您是否可以在本地重现该错误。如果一切正常，我会尝试再次将您的最新代码重新部署到heroku。
