2020-10 macos 安装 Homebrew

1.访问https://brew.sh/官网

2.打开macos终端执行以下命令

/bin/bash -c "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/HEAD/install.sh)"

执行命令后，如果发现如下报错，就进行第3步，如果成功就

3.直接浏览器访问以下地址，在浏览器上把里边的内容拷贝出来，如果还是访问不了，我已经把内容拷贝出来，放到了文章最后

https://raw.githubusercontent.com/Homebrew/install/HEAD/install.sh 

4.在终端用以下命令创建一个shell文件，将第3步拷贝出的内容，复制到文件里

mkdir brewinstall.sh

5.在brewinstall.sh文件中，将以下内容进行修改

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

改为

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

6.然后执行以下命令

/bin/bash brewinstall.sh

7.进入下面的 Taps 目录，clone homebrew-core

cd /usr/local/Homebrew/Library/Taps/homebrew (如果没有homebrew,新建homebrew文件夹)

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

8.把homebrew repo切换为清华镜像

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

9.完成

补充：https://raw.githubusercontent.com/Homebrew/install/HEAD/install.sh 中的内容
