mac装brew

Mac下使用国内镜像安装Homebrew
一、根据官网上的方法，在终端输入：

/usr/bin/ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install)"
二、下载修改安装文件

https://raw.githubusercontent.com/Homebrew/install/master/install

然后另存文件传回来，后做如下修改。

安装全文如下：

安装

/usr/bin/ruby ~/brew_install

替换homebrew源

替换homebrew默认源

cd "$(brew --repo)"

git remote set-url origin git://mirrors.ustc.edu.cn/brew.git

替换homebrew-core源

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

git remote set-url origin git://mirrors.ustc.edu.cn/homebrew-core.git

brew更新

brew update

设置 bintray镜像

echo 'export HOMEBREW_BOTTLE_DOMAIN=https://mirrors.ustc.edu.cn/homebrew-bottles' >> ~/.bash_profile

source ~/.bash_profile

第二坑开始，提示找不到Command_Line_Tools

好吧，安装了xcode都不行，按你的要求来，在苹果官网下载一个。

苹果官网：https://developer.apple.com/download/more/

接着安装，第三坑出现，说是/usr/local/Homebrew/Library/Taps/homebrew/homebrew-core不存在，好吧，我给你建。
三、如果遇到如下问题可以参考下

错误一:fatal: Not a git repository (or any of the parent directories): .git

解决办法:git init

错误二:/usr/local/.git: Permission denied

解决办法:

//确保目录归属管理组

sudo chgrp -R admin /usr/local

//确保管理组可读

sudo chmod -R g+w /usr/local

错误三:fatal: No such remote 'origin'

解决办法:set-url 改成 add

四、查看当前目录远程信息

git remote -v

五：No formulae found in taps.
