我正在将我的 rails 应用程序部署到 Engine Yard。
到目前为止我所拥有的：1. 创建了 SSH，嘿 2. 将公钥安装到 Engine Yard 应用程序。3. ssh deploy@my.server.ip.address
我被安置在 home/deploy，这不是执行 git pull 的正确位置。
我需要以这种方式部署的原因是因为我的应用程序使用的是 nmatrix gem，需要使用 c++ 编译器手动安装。自动捆绑器在获取该 gem 时出错，并停止。
更新：我想我的问题应该是，如何将 nmatrix 安装到 EngineYard。这是我通过调用 gem install nmatrix 得到的错误消息：

安装 nmatrix 的先决条件之一是 gcc > v4.7，但 EngineYard 只有 v4.5.4。有人知道如何升级 gcc 吗？我想我正在运行Gentoo。
