我可能做了一些不明智的事情。在brew update和brew doctor不断抛出相同的错误之后，我尝试使用这些脚本的shell脚本进行卸载并重新安装。它们大多数都起作用，但是在重新安装后，我收到了由普通自制安装输出记录的相同错误。因此，现在除了失去自制软件以外，我还失去了所有由Brew安装的工具。目前还不清楚我为解决这个问题而搞砸了什么。错误输出如下：

答案 0 :(得分：1)
希望我对此线程还不算太晚，我之前肯定已经看过这个问题。
您可以尝试以下两行以查看是否有帮助吗？
/usr/local/Homebrew/Library/Homebrew/vendor/portable-ruby/2.6.3_1/bin/gem update --system
/usr/local/Homebrew/Library/Homebrew/vendor/portable-ruby/2.6.3_1/bin/gem pristine --all
最坏的情况是，您只需要删除~/.gems，brew将重新下载gem依赖项。
如果可以附加您的MacOS信息，很好。
