安装导轨 - “导轨新”不起作用

Question

我试图安装导轨。我是这个新手，很遗憾，如果我错过了一些明显的东西。我已经得到了大多数事情的工作，但是当我真正尝试“轨新博客”，我得到以下错误：

我搜索周围的方式来解决它（尝试创业板安装导轨几次，摆弄其他一些东西），但我无法让它工作。我真的很感谢一些帮助。我正在开发OS X Lion，并安装了Ruby和RVM等等。不能为我的生活弄清楚我做错了什么。

谢谢！

PS - 如果我执行与 “命令” 上面，它返回：

/Users/sashafklein/.rvm/rubies/ruby-1.9.3-p194/lib/ruby/site_ruby/1.9.1/rubygems/dependency.rb:247:in `to_specs': Could not find railties (>= 0) amongst [bigdecimal-1.1.0, io-console-0.3, json-1.5.4, minitest-2.5.1, rake-0.9.2.2, rdoc-3.9.4] (Gem::LoadError)

的事情是，我绝对有railties。并试图通过gem install重新安装不能解决任何问题。

我遇到了完全相同的问题（在Mac上）。当我尝试在HOME目录中的文件夹中创建应用程序时，发生同样的错误。但是，当我在其中一个用户文件夹尝试相同的用户名/用户名它的工作。我猜想一些关于root权限的问题。希望这可以帮助。
