Question

我正在尝试学习Ruby，而我发现安装它的最常见方法之一是RVM。运行rvm install 2.1.2以获取最新版本后，它似乎完成正常，但在执行ruby -v时会显示此输出：

chris @ ubuntu：〜$ ruby -v
ruby 1.9.3p484（2013-11-22修订版43786）[x86_64-linux]

这是错误的版本。执行rvm list仅显示2.1.2：

chris @ ubuntu：〜$ rvm list
  rvm红宝石
  = * ruby-2.1.2 [x86_64]

做一个rvm reinstall 2.1.2也很好，但我仍然安装了错误的Ruby版本。这是输出：

chris@ubuntu:~$ rvm reinstall ruby-2.1.2

Answer 1

尝试

rvm use <your ruby version>

安装只安装它。它没有使用它。

通过RVM安装时，ruby版本不正确
