Mac 解决brew一直卡在Updating Homebrew

转载：https://www.jianshu.com/p/7cb05a2b39a5

运行命令brew install node，结果界面一直卡在Updating Homebrew...上，有两种解决办法

方法一：直接关闭brew每次执行命令时的自动更新（推荐）

vim ~/.bash_profile

# 新增一行
export HOMEBREW_NO_AUTO_UPDATE=true

方法二：替换brew源

cd "$(brew --repo)"
git remote set-url origin https://mirrors.ustc.edu.cn/brew.git

#替换homebrew-core.git
cd "$(brew --repo)/Library/Taps/homebrew/homebrew-core"
git remote set-url origin https://mirrors.ustc.edu.cn/homebrew-core.git
brew update


# 备用地址-1
cd "$(brew --repo)"
git remote set-url origin https://git.coding.net/homebrew/homebrew.git
brew update


# 备用地址-2
cd "$(brew --repo)"
git remote set-url origin https://mirrors.tuna.tsinghua.edu.cn/git/brew.git
cd "$(brew --repo)/Library/Taps/homebrew/homebrew-core"
git remote set-url origin https://mirrors.tuna.tsinghua.edu.cn/git/homebrew-core.git
brew update

如果备用地址都不行，那就只能再换回官方地址了

#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
