運行命令brew install node唧席，結(jié)果界面一直卡在Updating Homebrew...上昵时，有兩種解決辦法
方法一：直接關(guān)閉brew每次執(zhí)行命令時的自動更新（推薦）
vim ~/.bash_profile
# 新增一行
export HOMEBREW_NO_AUTO_UPDATE=true
方法二：替換brew源
cd "$(brew --repo)"
git remote set-url origin https://mirrors.ustc.edu.cn/brew.git
#替換homebrew-core.git
cd "$(brew --repo)/Library/Taps/homebrew/homebrew-core"
git remote set-url origin https://mirrors.ustc.edu.cn/homebrew-core.git
brew update
# 備用地址-1
cd "$(brew --repo)"
git remote set-url origin https://git.coding.net/homebrew/homebrew.git
brew update
# 備用地址-2
cd "$(brew --repo)"
git remote set-url origin https://mirrors.tuna.tsinghua.edu.cn/git/brew.git
cd "$(brew --repo)/Library/Taps/homebrew/homebrew-core"
git remote set-url origin https://mirrors.tuna.tsinghua.edu.cn/git/homebrew-core.git
brew update
如果備用地址都不行宴卖，那就只能再換回官方地址了
#重置brew.git
cd "$(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
