最近在使用Brew的时候，遇到了：
****** Second, We should find the update. [brew update] ******
fatal: not in a git directory
Warning: No remote 'origin' in /opt/homebrew/Library/Taps/homebrew/homebrew-services, skipping update!
Already up-to-date.很受启发的是这条comment：
在homebrew-core目录下，执行了git remote -v:
mokin.li@MoKinLiMacBook-Pro homebrew-core % git remote -v
origin https://github.com/Homebrew/homebrew-core (fetch)
origin https://github.com/Homebrew/homebrew-core (push)然后去homebrew-services目录下执行：
mokin.li@MoKinLiMacBook-Pro homebrew % cd homebrew-services
mokin.li@MoKinLiMacBook-Pro homebrew-services % git remote -v
fatal: detected dubious ownership in repository at '/opt/homebrew/Library/Taps/homebrew/homebrew-services'
To add an exception for this directory, call:
git config --global --add safe.directory /opt/homebrew/Library/Taps/homebrew/homebrew-services
mokin.li@MoKinLiMacBook-Pro homebrew-services % git config --global --add safe.directory /opt/homebrew/Library/Taps/homebrew/homebrew-services
mokin.li@MoKinLiMacBook-Pro homebrew-services % git remote -v
origin https://gitee.com/cunkai/homebrew-services.git (fetch)
origin https://gitee.com/cunkai/homebrew-services.git (push)通过这种方式成功解决了问题：
mokin.li@MoKinLiMacBook-Pro ~ % ./BrewToolsDaily.sh
