导轨控制台错误readline加载错误

我遇到了rails控制台的问题。当我尝试安装readline模块时，它给了我这个错误：导轨控制台错误readline加载错误

yum install readline-devel

我正在使用Rails 3.1.1在Fedora 14机器上工作。

/home/led/.rvm/rubies/ruby-1.9.2-p290/lib/ruby/1.9.1/irb/completion.rb:9:in `require': no such file to load -- readline (LoadError) 
    from /home/led/.rvm/rubies/ruby-1.9.2-p290/lib/ruby/1.9.1/irb/completion.rb:9:in `<top (required)>'

我尝试安装通过RVM的readline以下链接 [通过RVM readline的安装] [1]

和轨道ç工作，但问题是当重新引导系统，并试图它再次出现，显示此错误

请参阅：http://biztech.sheprador.com/?p=81卸载红宝石，readline等，然后重试。 – Behrang 2012-01-12 17:39:54

您需要安装readline的头文件和库之前安装Ruby解释器（一旦你完成RVM安装它显示）

你可以看到，再做rvm notes

检查readline的宝石安装。上面的yum命令安装readline库，但为了与它交互，你需要gem。

如果它不在您的Gemfile中，请添加它，运行bundle install并再次检查。
