我只安装了readline 7,我找不到在macOS Sierra上安装版本6的单一方法.这是尝试运行rails c时的错误：
/Users/akashagarwal/.rvm/gems/ruby-2.3.0@global/gems/activesupport-5.0.0.1/lib/active_support/dependencies.rb:293:in `require’: dlopen(/Users/akashagarwal/.rvm/rubies/ruby-2.3.0/lib/ruby/2.3.0/x86_64-darwin15/readline.bundle,9): Library not loaded: /usr/local/opt/readline/lib/libreadline.6.dylib (LoadError)

解决方法
我有一个类似的问题,并解决了：
ln -s /usr/local/opt/readline/lib/libreadline.7.0.dylib /usr/local/opt/readline/lib/libreadline.6.dylib
