mac OS使用brew安裝提示Command failed with exit 128: git

在使用brew 安裝ffmpeg的時候出現以下問題：

經過一番折騰，記錄以下解決方式：

通過brew -v指令來檢視下是否有以下提示：

Homebrew 3.6.7-28-g560f571
fatal: detected dubious ownership in repository at '/opt/homebrew/Library/Taps/homebrew/homebrew-core'
To add an exception for this directory, call:

	git config --global --add safe.directory /opt/homebrew/Library/Taps/homebrew/homebrew-core
Homebrew/homebrew-core (no Git repository)
fatal: detected dubious ownership in repository at '/opt/homebrew/Library/Taps/homebrew/homebrew-cask'
To add an exception for this directory, call:

	git config --global --add safe.directory /opt/homebrew/Library/Taps/homebrew/homebrew-cask
Homebrew/homebrew-cask (no Git repository)
itxdd@itxdddeMacBook-Pro anzhuang % git config --global --add safe.directory /usr/local/Homebrew/Library/Taps/homebrew/homebrew-core
           

如果出現以上資訊的話，隻需要安裝上面的提示執行以下指令：

git config --global --add safe.directory /opt/homebrew/Library/Taps/homebrew/homebrew-core
           

git config --global --add safe.directory /opt/homebrew/Library/Taps/homebrew/homebrew-cask
           

git config --global --add safe.directory /opt/homebrew/Library/Taps/homebrew/homebrew-services
           

問題找到解決方式之後，就感覺其實很簡單。
