我在 Stack Overflow 和 Brew 问题页面 (https://github.com/mxcl/homebrew/wiki/Common-Issues#brew-update-complains-about-untracked-working-tree-files) 上尝试了很多东西，但仍然没有运气。它看起来像一个稍微不同的错误，因为它抱怨自制/欺骗。

Answer 1

试试这个：

$ cd $(brew --prefix)/Library/Taps/homebrew-dupes/
$ git checkout .
$ git pull --force
$ brew update
