我有一个EC2实例Amazon运行Ubuntu 14.4.3。 这将运行Vagrant并使用vagrant-aws插件部署一些虚拟机。 但每次我尝试安装插件给我的跟随误差：如何在Ubuntu 14.04中为Vagrant安装Ruby版本> = 2.0？

我有Ubuntu相同的版本在我desktop机，并没有这个问题。我究竟做错了什么 ？我试图删除ruby1.9并只安装ruby2.2但仍然给出相同的错误。

这是不可能的:)'ruby -v'返回什么？ –
好吧，看起来vagrant对ruby 1.9有很强的依赖性，所以你需要手动安装ruby 2.2并确保2.2在PATH中首先出现。所以当你运行'vagrant插件安装vagrant-aws'时，'ruby -v'应该返回'2.2.3'， –
你最近流浪的版本是什么？ –
