Question

gem list

我说

rails（2.3.5,2.3.2）

但是当我给出

rails -v

它吐出错误

/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'

    from /usr/local/lib/site_ruby/1.8/rubygems.rb:49:in `gem'
    from /usr/bin/rails:18

任何可能的解决方案？

首先，您应该告诉您安装ruby和rails的步骤..

使用

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

检查是否有rvm要求..

rvm要求

然后使用

gem install rails -v version

你也可以参考

https://rvm.io/

Rails -v给出了错误
