【问题描述】：

我正在按照 Michael Hartl 的 rails 教程进行操作，并尝试将某些东西部署到 Heroku。一切顺利，直到我运行

    git push heroku master

当我收到此错误时。

我猜这是由于 heroku 无法运行 ruby 2.0.0，但我检查了他们的文档，发现 2.0.0 在 heroku 上仍然有效。这是链接https://devcenter.heroku.com/articles/ruby-support#supported-runtimes。

我使用的是 Rails 4.0.8 和 Ruby 2.0.0

【问题讨论】：

根据日志，这不是你的错 - 他们的 ruby 构建包有问题。您是否就这个问题征求过他们的支持？

标签： ruby-on-rails ruby heroku

【解决方案1】：

由于是测试站点，你可以在你的 Gemfile 中评论 ruby 版本，然后提交并推送到 heroku

【讨论】：

【解决方案2】：

在 Gemfile 中评论 ruby '2.0.0' 并推送到 heroku。

【讨论】：

【解决方案3】：

Heroku 不支持 Ruby 2.0.0。就像它在错误中所说的那样，您可以找到哪些 ruby 运行时工作 here
