我的系统是OSX 10.11.6。
我遇到了这个错误：

我试过跑步
brew doctor但我最终得到了完全相同的错误。
我在这里尝试了解决方案：Cannot update brew in MAC OS X el capitan and keep getting a Load error with require。我也尝试重新安装brew，我最终得到了同样的错误。即使我输入brew，我也会得到同样的错误。但是，当我输入brew update时，它会告诉我Already up-to-date。
我输入brew cleanup我收到同样的错误。
有什么问题？这是一些许可问题吗？
答案 0 :(得分：0)
我有同样的问题。 File＆＃34; /Library/Ruby/Gems/2.0.0/specifications/terminal-notifier-1.6.0.gemspec"由于某种原因具有无效权限（只读给所有者，而不是组）。可以通过向该文件的组添加读取权限来修复它，如：
sudo chmod g+r /Library/Ruby/Gems/2.0.0/specifications/terminal-notifier-1.6.0.gemspec
