我遇到了这个错误：

/Users/myuser/.rvm/rubies/ruby-2.0.0-p247/lib/ruby/2.0.0/irb/completion.rb:9:in `require': dlopen(/Users/myuser/.rvm/rubies/ruby-2.0.0-p247/lib/ruby/2.0.0/x86_64-darwin12.5.0/readline.bundle, 9): Library not loaded: /usr/local/opt/readline/lib/libreadline.6.2.dylib (LoadError)

升级到小牛后，但这修复了它：

brew link readline --force

我所有的 brew 链接现在都坏了吗？我该如何轻松解决这个问题？

【问题讨论】：

【解决方案1】：

从Reinstalling homebrew symbolic links after a restore，您可以重新链接所有已安装的 brew 公式：

brew list | xargs -I % sh -c 'brew unlink %; brew link %'
