homebrew 安装踩坑解决过程

1、坑一：mac 安装brew报错 Failed to connect to raw.githubusercontent.com port 443: Connection refused解决办法

安装brew执行：

/usr/bin/ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install)"

报错如下：

Failed to connect to raw.githubusercontent.com port 443: Connection refused

主要还是墙的问题，解决方案：
在hosts中加入代理hosts

200.199.232.28.133 raw.githubusercontent.com

2、坑二

fatal: index-pack failed

Error: Failure while executing; /usr/local/bin/brew tap homebrew/core exited with 1.
Failed during: /usr/local/bin/brew update --force

这个时候我们换个源，执行：
