mac中使用brew install opencv出現錯誤

首先查看brew update升級信息

brew update --verbose --force

fatal: Needed a single revision

以前修改過源,致使出現416,git更新失敗.

重置全部源

重置brew.git:
cd "$(brew --repo)"
git remote set-url origin https://github.com/Homebrew/brew.git

重置homebrew-core.git:
cd "$(brew --repo)/Library/Taps/homebrew/homebrew-core"
git remote set-url origin https://github.com/Homebrew/homebrew-core.git

 

brew update --verbose --force 

繼續執行

Updating /usr/local/Homebrew/Library/Taps/caskroom/homebrew-cask...
fatal: Needed a single revision

須要進入到 /usr/local/Homebrew/Library/Taps/caskroom/homebrew-cask

git pull 
From https://github.com/Caskroom/homebrew-cask
 * branch                  HEAD       -> FETCH_HEAD

從新執行 brew update 恢復正常.

繼續brew search opencv2

正常找出2個庫.

brew  install opencv@2
