Answer 1

理想情况下,您可以使用RVM或rbenv创建本地沙箱并处理Ruby安装和gem,而不是系统默认值.然后你不必使用sudo你可以使用gem uninstall <gem>.它不会让你有理由访问,因此不小心搞乱了系统Ruby.

如果您可以阅读这些安装说明以使用RVM进行设置,然后安装先前在新环境中使用的gem.在将来管理Ruby和宝石时,它将为您节省很多麻烦.

如果您不想这样做,您可以尝试这个答案

从这个相关问题中尝试这个答案.

gem list -d 'name of gem' 并注意"已安装在:"位置

sudo gem uninstall 'name of gem' -i 'the path noted above'

如果仍然返回权限错误.在上面的路径中创建一个文件夹/ bin.继续卸载,如步骤2,仍然使用原始路径(/System/Library/Frameworks/Ruby.framework/Versions/1.8/usr/lib/ruby/gems/1.8).
