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:
