导轨（2.3.5、2.3.2）

但是当我给

它吐出一个错误

/usr/local/lib/site_ruby/1.8/rubygems.rb:578:in `report_activate_error': Could not find RubyGem test-spec (>= 0) (Gem::LoadError)
    from /usr/local/lib/site_ruby/1.8/rubygems.rb:134:in `activate'

首先你应该告诉你安装 ruby​​ 和 rails 的步骤。

利用

$ \curl -L https://get.rvm.io | bash -s stable --rails --autolibs=enabled # 或者，--ruby=1.9.3

检查是否存在 rvm 要求..

rvm 要求

然后使用

gem install rails -v 版本

你也可以参考
