当我在终端中运行brew时,我得到一个错误:

当前回答

更新到El Capitan后,/usr/local具有root:wheel权限。

使用以下命令将权限更改回用户:

sudo chown -R $(whoami):admin /usr/local

and:

brew doctor && brew update

这帮助我重新启动了Homebrew。

其他回答

首先,打开一个终端会话并运行:

cd /usr/local/
git status

看看家酿啤酒是否干净

如果是脏的,运行:

git reset --hard && git clean -df

then

brew doctor
brew update

如果它还是坏了,在你的疗程中试试这个:

sudo rm /System/Library/Frameworks/Ruby.framework/Versions/Current
sudo ln -s /System/Library/Frameworks/Ruby.framework/Versions/1.8 /System/Library/Frameworks/Ruby.framework/Versions/Current

这将迫使Homebrew在系统安装时使用Ruby 1.8。

这个问题应该在最新版本的Homebrew中得到解决。尝试重新安装它,Homebrew主页上有描述。

要恢复您的Homebrew设置,请尝试以下操作:

cd /usr/local/Homebrew/Library && git stash && git clean -d -f && git reset --hard && git pull

在我的情况下,我只需要删除Homebrew的可执行文件使用:

sudo rm -f `which brew`

然后重新安装Homebrew:

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

更新到El Capitan后,/usr/local具有root:wheel权限。

使用以下命令将权限更改回用户:

sudo chown -R $(whoami):admin /usr/local

and:

brew doctor && brew update

这帮助我重新启动了Homebrew。
