Ruby on rails 出了点问题。Heroku应用程序问题

所以Heroku已经停机一整天了，当然，直到我对我的应用程序做了大量的修改之后，我才意识到这一点。现在Heroku恢复了，我的应用程序坏了

这是一个随机文本块，使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：

<%= landing_photo %>

假设您没有向Heroku推送任何引入错误代码的新代码

---

我会检查你是否能在本地重现错误。如果一切都是可靠的，我会再次尝试将您的最新代码重新部署到heroku。

您对rand方法使用了错误的参数，它只接受一个整数，而不接受它们的范围

你在找什么

random = Random.rand(4)

您的另一个选项不是使用Random，而是使用

---

这可能是Ruby版本的问题，因为在我运行MRI-1.9.3的系统上，

random=random.rand（1..4）

可以正常工作。也许是电风暴让Heroku改变了你的红宝石。也许你在1.9.3中依赖的是现在已经不存在的实验室插件

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

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

---

该错误似乎是

landing\u photo

方法中的某种转换错误，从日志中我可以看出，它似乎与某种类型的随机数发生器有关。试试看你是否可以在本地复制它，或者在这里放一些代码（例如，

landing\u photo

方法）。@Frost Ok我添加了随机化程序代码。奇怪的是，这可能会导致一个问题，据我所知，这段代码在Heroku倒下之前就没有被触动过。本地一切都很好。我在停机期间推动了一些更改，更新了rails版本等。我尝试恢复到更改任何内容之前的代码方式。我推了我的最新代码，仍然不起作用..兰德确实接受MRI-1.9.3中的一个范围，所以如果这个代码起作用，那么应用程序运行的Ruby版本可能已经发生了某种变化。我想你已经了解了一些情况。但是，当我将那个ruby版本添加到我的GEM文件时，我无法运行bundle。它返回了一个错误。啊，我认为您可能需要将bundler版本升级到-just run

gem install bundler-v1.2.0.pre--pre

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

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