I'm so frustrated. I just wiped my computer clean for a new start, after trying for several days to get rails installed. I followed this tutorial http://www.moncefbelyamani.com/how-to-install-xcode-homebrew-git-rvm-ruby-on-mac/#step-4

It actually worked too, but when I woke up the next morning, I got this new "error"

Everything seemed to be working. I installed xcode, homebrew first, and then installed RVM. and it all seems to be working. I have ruby 2.0.0, but when I type "rails -v" after installing I get the following:

$ rails -v

Please help. I've been trying for three days and even completely reset my computer. and I am so close. What do I need to do?

好的，退后一步，深呼吸。该教程有点有害，因为它没有向您展示 RVM rubies、gems 和 gemsets 的各个步骤，而是在一个命令中完成。

首先，使用此命令检查您安装了哪些 ruby

rvm list

这将打印出您已安装的内容，如下所示

   ruby-1.9.3-p385 [ x86_64 ]
   ruby-1.9.3-p392 [ x86_64 ]
=* ruby-2.0.0-p0 [ x86_64 ]

# => - current
# =* - current && default
#  * - default

现在看起来你有 2.0.0，让它成为默认的 ruby

rvm use 2.0.0 --default

现在让我们创建一个名为 的 gemset rails-3.2.13，这是我们将安装 rails gem 的地方

rvm gemset create rails-3.2.13

让这个 gemset 成为当前使用的默认 gemset

rvm gemset use rails-3.2.13 --default

安装导轨的时间

gem install rails -v 3.2.13

现在，当您键入时，rails -v它应该会显示此版本的 rails。另外，因为我们将默认设置为ruby 2.0.0，而 gemset 设置为rails-3.2.13，所以每次打开一个新终端时，它都是相同的 ruby​​ 和 rails 版本。

查看RVM 网站和文档，了解 rvm 可以做的其他一千件事。祝你好运
