Capistrano部署失败rvm-shell说rvm没有被发现

Question

最近我继承了一个Rails应用程序，已经部署到生产中很多次。我以前部署到临时环境。现在，它无法部署到任一个。然而，另一个部署到具有相同帐户的相同服务器的Rails应用程序成功部署了使用rvm和capistrano。

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。

Answer 1

这是一个rvm/rvm-capistrano版本不匹配。检查服务器上安装的rvm的版本，并与捆绑安装的rvm-capistrano版本进行比较。如果您的服务器具有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.

我在回答我自己的问题，因为我必须弄清楚这个难题。回想起来很明显，但是当你第一次看到这个错误的时候并不是这样。这是没有在Gemfile中指定产品版本的情况。通常，我们广泛的测试套件会捕获这样的问题，但是我们的测试套件并未覆盖部署，所以我们错过了这个测试套件，直到为时已晚。
