【问题讨论】：

你需要2.2.5吗？为什么不试试 2.3.1？
我克隆了一个 repo，当我进行捆绑安装时，我收到错误 ruby_dep-1.5.0 requires ruby version >= 2.2.5, ~> 2.2，它与当前版本 ruby 2.0 不兼容.0p648
嗯，2.3.1 符合这些要求，并且可能已经解决了您在这里遇到的问题。看起来您缺少 libgmp 库，通常 RVM 非常适合排列这些依赖项。

【解决方案1】：

这个很有魅力

rvm install 2.2.5 --with-gcc=clang

【解决方案2】：

你在这里没有给我们太多信息。你在运行什么操作系统？哪个版本？
根据this issue on the Ruby GitHub page，您可以通过使用 GCC 安装来解决此问题：CC=/usr/bin/gcc rvm install ruby-2.2.5，假设您已将 GCC 安装到/usr/bin/gcc

这不是真正的答案。
