尝试在 OS X 10.8 上安装 RoR。Mac 和 RoR 的新手！
遵循这里的指示：
http://www.justinball.com/2012/10/22/install-rvm-on-mac-osx-mountain-lion/
已安装 XCode、命令行工具、XQuartz、Homebrew、gcc、最新 RVM，已执行
“rvm pkg install openssl”，最后是“rvm install 1.9.3”
在此过程中出现了一些错误消息，我稍后会提供。
但是，根据以下情况，安装似乎成功：
$ 类型 rvm | 头-n1
rvm 是一个函数
$导轨-v
导轨 3.2.8
红宝石--版本
ruby 1.9.3p286（2012-10-12 修订版 37165）[x86_64-darwin12.2.0]
安装过程中的错误/警告包括：
警告：无法在 mxcl/master/vim 上点击 homebrew/dupes/vim
获取 ruby 解释器时出错。停止安装。
创建了一个名为“agile”的新目录，更改为该目录并执行：
“轨道新演示”
在输出的第一行得到“`mkdir': Permission denied”
然后尝试“sudo rails new demo”
在输出的第一行得到“Could not find Rake”
（本文末尾提供了完整输出。）
尝试了各种方法来查看 rake、rails、ruby 或 rvm 是否有问题，但似乎一切都恢复正常了。
