最近，我继承了一个已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，使用rvm和capistrano成功部署到具有相同帐户的相同服务器的另一个Rails应用程序。
我收到以下错误：

我检查了服务器。 RVM已安装并正常运行。
答案 0 :(得分：1)
这是rvm / rvm-capistrano版本不匹配。检查服务器上安装的rvm版本，并与安装了bundle的rvm-capistrano版本进行比较。如果您的服务器具有rvm 1.18.x，则将您的Gemfile中的rvm版本锁定到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，因为我必须努力解决这个问题。回想起来很明显，但是当你第一次看到错误时就不会这样。这是无法在Gemfile中指定产品版本的情况。一般来说，我们广泛的测试套件会遇到这样的问题，但是我们的测试套件不包括部署，所以我们错过了这个，直到为时已晚。
