【问题描述】：

我是 Ruby 新手，默认情况下我的 Mac 上安装了 2.0.0 版本的 Ruby。我试图获取最新版本，并关注了这个问题：How to update Ruby to 1.9.x on Mac?，但即便如此，最新版本仍然是2.0.0。我复制了一些我使用的终端命令：

Installing RVM to /Users/manishgiri/.rvm/
    Adding rvm PATH line to /Users/manishgiri/.profile /Users/manishgiri/.mkshrc /Users/manishgiri/.bashrc /Users/manishgiri/.zshrc.
    Adding rvm loading line to /Users/manishgiri/.profile /Users/manishgiri/.bash_profile /Users/manishgiri/.zlogin.
Installation of RVM in /Users/manishgiri/.rvm/ is almost complete:

  * To start using RVM you need to run `source /Users/manishgiri/.rvm/scripts/rvm`
    in all your open shell windows, in rare cases you need to reopen all shell windows.

# Manish-Giri,
#
#   Thank you for using RVM!
#   We sincerely hope that RVM helps to make your life easier and more enjoyable!!!

Manish-MBP:~ manishgiri$ brew update
Error: The /usr/local directory is not writable.
Even if this directory was writable when you installed Homebrew, other
software may change permissions on this directory. Some versions of the
"InstantOn" component of Airfoil are known to do this.

You should probably change the ownership and permissions of /usr/local
back to your user account.

看来自制软件有问题，所以我决定更新它。我做了更改所有权和权限部分，并按照这个问题的说明 - How do I update Homebrew? 并执行了brew update。我收到了Already upto date 回复。

接下来，我从第一个答案中尝试了rvm list known，只是为了验证最新版本，然后我执行了rvm install current && rvm use current。我收到了这样的回复：

毕竟，我以为它会升级到2.2.3，但是当我运行ruby -v时，我仍然得到：ruby 2.0.0p645 (2015-04-13 revision 50299) [universal.x86_64-darwin15]。

为什么更新失败？我在我的 Windows PC 上安装了 RubyInstaller，它使用 2.2.3。

【问题讨论】：

那么当您执行 rvm install 2.2.3 时会发生什么？

【参考方案1】：

尝试更新 Homebrew，退出终端，然后重新打开。然后 rvm install ruby​​-1.9.3-p551

还要确保将其设置为默认值。 rvm --default 使用 version #，退出终端，然后重新打开。

我偶然得到它。部分来自此 YouTube 视频：Setting Up Ruby [ Ruby on Rails from the Ground Up - 2/5 ]。剩下的就是用锋利的棍子戳它。
