Ruby 和 RVM：意外的版本号

Ruby 和 RVM：意外的版本号

我正在使用 osx 10.8.4 并且已经安装了 brew。

我按照这里的 ruby​​/rvm 安装说明进行操作：http://octopress.org/docs/setup/rvm/

rvm install 1.9.3
rvm use 1.9.3
rvm rubygems latest

它运行时没有问题和错误。当我检查 ruby​​ 版本时，我得到了这个：

$ ruby --version
ruby 2.0.0p195 (2013-05-14 revision 40734) [x86_64-darwin12.4.0]

这不是我所期望的。RVM 是否自动安装了更高版本的 ruby​​？

这是 rvminfo

$ rvm info

您确定rvm use 1.9.3工作正常并且没有显示错误吗？

您可以运行此命令以确保无误：

rvm use 1.9.3 && echo "Got 1.9.3" || echo "Failed switching ruby!"
