修复 Homebrew 误删 Cellar 文件夹

[Marthers]

Homebrew 之前一直无法 update，按照网上教程
rm -rf /usr/local/Cellar /usr/local/.git && brew cleanup
/usr/bin/ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/instal l/master/install)"

之后很多工具用不了了，系统剪切板也无效了，用 brew doctor 报出以下错误：
Warning: Unbrewed dylibs were found in /usr/local/lib.
If you didn't put them there on purpose they could cause problems when
building Homebrew formulae, and may need to be deleted.

Warning: Unbrewed header files were found in /usr/local/include.
If you didn't put them there on purpose they could cause problems when
building Homebrew formulae, and may need to be deleted.

求各位大神支支招，万分感谢！
