最近我继承了一个已经多次部署到生产环境的 Rails 应用程序。我之前已部署到暂存环境。现在，它无法部署到任何一个。但是，另一个使用相同帐户部署到相同服务器的 Rails 应用程序使用 rvm 和 capistrano 成功部署。

我收到以下错误：

我已经检查了服务器。RVM 已安装并正在运行。

这是 rvm/rvm-capistrano 版本不匹配。检查服务器上安装的 rvm 版本，并与捆绑安装的 rvm-capistrano 版本进行比较。如果您的服务器有 rvm 1.18.x，则将 Gemfile 中的 rvm 版本锁定为 1.2.x。rvm-capistrano 1.3.x 需要 rvm 1.19.x。

我正在回答我自己的问题，因为我必须以艰难的方式解决这个问题。回想起来很明显，但不是当您第一次看到错误时。这是在 Gemfile 中指定产品版本失败的情况。通常，我们广泛的测试套件会捕获此类问题，但我们的测试套件不涵盖部署，因此我们错过了这个，直到为时已晚。
