Homebrew 介绍与上手指南-大江小浪

Homebrew是一款macOS平台下的软件包管理工具，能够利用很简单的指令，帮助我们实现对开源软件的安装、更新、卸载等常用操作，省去了我们独立下载、编译、安装、配置各种开源软件的繁琐步骤。可以类比于Linux下的yum或者Ubuntu的apt-get。

Homebrew不仅能够帮我们安装一些命令行的开源软件和工具，例如wget/node等等，还能够帮助我们安装macOS图形界面的应用程序，例如Firefox。

使用介绍

$ brew install wget
卸载命令行工具

卸载图形界面应用程序
1

安装避坑

Homebrew的用法很简单，安装也很简单，官方网站就给了一行通用安装脚本。

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

但是现在因为众所周知的原因raw.githubusercontent.com这个域名访问会存在一些问题，可以利用ip138等网站解析出可以登陆的ip，然后通过修改 hosts 文件的方式来解决访问问题。但是下载速度依然会很慢，而且经常会出现下面的错误。

==> Downloading and installing Homebrew...

remote: Counting objects: 100% (54/54), done.

fatal: The remote end hung up unexpectedly
fatal: early EOF
fatal: index-pack failed
Failed during: git fetch origin --force
==> Installation successful!

错误信息中明确提示了git在获取文件的过程中失败了，但是仍有brew安装成功的信息打出来，因为shell安装脚本是顺序执行的，还缺少一些安装是否成功的校验，具体看下面的代码。

ohai "Downloading and installing Homebrew..."

  cd "${HOMEBREW_REPOSITORY}" >/dev/null || return
