RVM Ruby 2.3.0 DevKit未安装？

我试图建立在亚马逊Web服务on Rails的Ruby的RVM Ruby 2.3.0 DevKit未安装？

红宝石2.3.0 [x86_64的]与RVM
RVM 11年1月26日
导轨安装5.0.0beta3
Capistrano的3.4

当部署到服务器时，一切运行良好，直到与捆绑软件依赖安装。似乎是说DevKit没有与Ruby一起安装

如何检查RVM是否正确安装了DevKit？或者，也许这个问题在别的地方？它还提到缺少库/头

啊，只是发现和阅读的日志文件，它向我指出缺少库gmp

以下命令解决了这一问题：

sudo apt-get install libgmp3-dev
