导读：升级ruby和rails后进入script/consle出现：复制代码代码如下: /usr/local/lib/ruby/1.8/irb/completion.rb:10:in `require': no such file to load -- readline (LoadError) from /usr/local/lib/ruby/1.8/irb/completion.rb:10 from /usr/local/lib/ruby/

升级ruby和rails后进入script/consle出现：

复制代码代码如下:

/usr/local/lib/ruby/1.8/irb/completion.rb:10:in `require': no such file to load -- readline (LoadError)  

        from /usr/local/lib/ruby/1.8/irb/completion.rb:10  

        from /usr/local/lib/ruby/1.8/irb/init.rb:252:in `require'  

        from /usr/local/lib/ruby/1.8/irb/init.rb:252:in `load_modules'  

        from /usr/local/lib/ruby/1.8/irb/init.rb:250:in `each'  

        from /usr/local/lib/ruby/1.8/irb/init.rb:250:in `load_modules'  

        from /usr/local/lib/ruby/1.8/irb/init.rb:21:in `setup'  

        from /usr/local/lib/ruby/1.8/irb.rb:54:in `start'  

        from /usr/local/bin/irb:13

解决办法：

第一步：确认是否安装了libncurses5-dev libreadline5-dev,如果没有安装，就用

复制代码代码如下:

sudo apt-get install libncurses5-dev libreadline5-dev 进行安装

第二步：
