我正在使用带有 Torquebox 的 JRuby 1.7.1 运行 rails 应用程序，并尝试在 EC2 上进行部署，但在运行“cap deploy”时看到以下错误：

关于这里可能出现什么问题的任何想法？

Git 客户端未安装在您要部署到的盒子上。您可以通过以 root 身份登录到您的 ec2 实例并安装 get 来修复它。(yum install git 或 apt-get install git)

或者您可以将部署策略更改为复制，这比 :remote_cache 慢。复制将在您的本地计算机上签出，并将所有文件通过 scp/sftp 复制到正在部署的服务器上。

set :deploy_via, :copy

您的系统中需要“git”。apt-get install git应该做的伎俩。但是，您可能会遇到更多可能的问题。我在公司的博客上写了一篇文章来记录我的奋斗和解决方案。
