看了一下/System/Library/Frameworks/Ruby.framework/Versions/2.0/這個目錄下我根本沒有usr
求助該問題怎麼解決
brew 裡面是這麼寫的

1 #!/System/Library/Frameworks/Ruby.framework/Versions/Current/usr/bin/ruby -W0

我是通過這種方式解決的

cd /usr/local git fetch git reset --hard origin/master

解決方式的出處Stack

osx - Cannot update brew in MAC OS X el capitan and keep getting a Load error with `require`

卸載

ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/uninstall)"

從新安裝

/usr/bin/ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install)"

謝邀。

可能是許可權的問題

既然無法解決就用 git reset 將所有文件設置為已修改，文件都在 /usr/local 下，把沒被 tracked 過的刪掉，然後恢復所有被 tracked 過的...

如果還有問題應該就是 /usr/local 目錄許可權相關了。

大概：

cd /usr/local git reset --hard FETCH_HEAD git clean -df brew update

如果 brew update 提示 git pull 失敗提示「failed while git pull」之類，試試用 git checkout Library 替換新文件：

cd /usr/local/git git checkout Library

然後再 brew update，如果 terminal 里的提示信息是「Operation not permitted」，用 shown 指定一下 /usr/local 的目錄和組：

sudo shown -R rainy /usr/local //rainy 換成你的用戶名
