使用 brew update 時報錯：
情況是有一天要下載brew包挟裂，發(fā)現(xiàn)update時報錯如下。
brew update
Warning: No remote 'origin' in /opt/homebrew/Library/Taps/homebrew/homebrew-cask, skipping update!
Warning: No remote 'origin' in /opt/homebrew/Library/Taps/homebrew/homebrew-core, skipping update!
Warning: No remote 'origin' in /opt/homebrew/Library/Taps/homebrew/homebrew-services, skipping update!
Already up-to-date.
解決辦法：
1. 執(zhí)行doctor檢查程序
brew doctor
Please note that these warnings are just used to help the Homebrew maintainers
with debugging if you file an issue. If everything you use Homebrew for is
working fine: please don't worry or file an issue; just ignore this. Thanks!
Warning: Suspicious https://github.com/Homebrew/brew git origin remote found.
The current git origin is:
https://mirrors.ustc.edu.cn/brew.git
With a non-standard origin, Homebrew won't update properly.
You can solve this by setting the origin remote:
git -C "/opt/homebrew" remote set-url origin https://github.com/Homebrew/brew
Warning: Homebrew/homebrew-cask was not tapped properly! Run:
rm -rf "/opt/homebrew/Library/Taps/homebrew/homebrew-cask"
brew tap homebrew/cask
Warning: Homebrew/homebrew-core was not tapped properly! Run:
rm -rf "/opt/homebrew/Library/Taps/homebrew/homebrew-core"
brew tap homebrew/core
2. 然后按照doctor的指示進(jìn)行操作
git -C "/opt/homebrew" remote set-url origin https://github.com/Homebrew/brew
rm -rf "/opt/homebrew/Library/Taps/homebrew/homebrew-cask"
brew tap homebrew/cask
Warning: No remote 'origin' in /opt/homebrew/Library/Taps/homebrew/homebrew-core, skipping update!

brew update

Error: Fetching /opt/homebrew failed!
Updated 2 taps (homebrew/core and homebrew/cask).
雖然能進(jìn)行update了蛋铆，但是還是有一個remote倉庫連不上滨溉。于是需要將homebrew-services也進(jìn)行重裝.
rm -rf "/opt/homebrew/Library/Taps/homebrew/homebrew-services"
