homebrew安装

前言：前几年离不开homebrew，安装软件弄个命令超级便利，年初换了新mac，最近在安装homebrew遇到一些问题，安装顺利，总是告诉403错误，原因嘛，有墙，你懂。

正式开始

1. 首先去官网https://brew.sh/index_zh-cn

2. copy命令到终端，回车。

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

得到如下错误

curl: (7) Failed to connect to raw.githubusercontent.com port 443: Connection refused

3. 浏览器访问https://raw.githubusercontent.com/Homebrew/install/master/install.sh 能够看到

那就需要host文件来解决问题。

4.浏览器https://www.ipaddress.com/ 查询 raw.githubusercontent.com的ip地址

我当前查询到的ip地址是199.232.68.133，你在配置时候，需要查询一次，地址可能会更新。

5.终端执行命令

sudo vi /etc/hosts

输入密码后，

添加一行

199.232.68.133 raw.githubusercontent.com

保存并退出。

6.再次执行步骤2，慢慢等着，大概300+MB，1个小时左右

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

后记：受环境限制，不能安装其他代理。如果你有vpn，可自行*，不需要这样做，而且速度也比较快。当然安装brew后，主要是使用tree命令，来扫一下代码src文件的目录结构，用于梳理文档。
