Ruby 前端之家
前端之家收集整理的这篇文章主要介绍了ruby-on-rails – 导轨c不在导轨5中工作，前端之家小编觉得挺不错的，现在分享给大家，也给大家做个参考。
在rails 5应用程序内的终端中使用命令 
rails c

抛出的错误如下所示.我不知道这在类似的问题中意味着什么,解决方案是使用弹簧停止.我也试过了,但没有它仍然给出同样的错误.如果有人能指出这里的错误,那就太好了.

解决方法

当我更新HomeBrew时,我最近遇到了这个问题,我也在使用rails 5并找到了这个解决方案,它对我有用： 
ln -s /usr/local/opt/readline/lib/libreadline.7.0.dylib /usr/local/opt/readline/lib/libreadline.6.dylib
