最近換了Mac,安裝Homebrew很慢（以前好像并沒有這么慢）,Downloading and installing Homebrew...只有10KB/S.解決方法主要思路是把git切換為清華鏡像，話不多說，直接看步驟吧.

1.用safari打開“https://raw.githubusercontent.com/Homebrew/install/master/install.sh”,把里面的文本復(fù)制下來，在桌面創(chuàng)建文本文件“brew_install”,粘貼.

2.搜索:

BREW_REPO="https://github.com/Homebrew/brew"

替換成:

BREW_REPO="https://mirrors.ustc.edu.cn/brew.git"

保存.

3.打開terminal,運(yùn)行命令:/bin/bash + 剛才的brew_install文件,比如:

/bin/bash /Users/admin/Desktop/brew_install

4.進(jìn)入下面的 Taps 目錄，clone homebrew-core

cd /usr/local/Homebrew/Library/Taps/homebrew (如果沒有homebrew,新建homebrew文件夾)

git clone https://mirrors.tuna.tsinghua.edu.cn/git/homebrew/homebrew-core.git

5.把homebrew repo切換為清華鏡像

cd "$(brew --repo)"

git remote set-url origin https://mirrors.tuna.tsinghua.edu.cn/git/homebrew/brew.git

cd "$(brew --repo)/Library/Taps/homebrew/homebrew-core"

git remote set-url origin https://mirrors.tuna.tsinghua.edu.cn/git/homebrew/homebrew-core.git

brew update

PS:如果有報(bào)錯(cuò)：curl: (7) Failed to connect to raw.githubusercontent.com port 443: Connection refused，可以通過這個(gè)命令解決：sudo gem install redis

備注：其中我在安裝的homebrew-core的時(shí)候總是不成功

使用git clone git://mirrors.ustc.edu.cn/homebrew-core.git/ /usr/local/Homebrew/Library/Taps/homebrew/homebrew-core --depth=1
來下載homebrew-core
