Mac 安装homebrew

Homebrew是一款Mac OS平台下的软件包管理工具，拥有安装、卸载、更新、查看、搜索等很多实用的功能。简单的一条指令，就可以实现包管理，而不用你关心各种依赖和文件路径的情况，十分方便快捷。

安装

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

但是个人觉得可能是国内网络的问题经常下载并不是很顺利，经常443拒绝访问

如何解决

• 在任意浏览器输入https://raw.githubusercontent.com/Homebrew/install/master/install
  保存网页的内容于任意路径，并命名为brew_install.rb
• 进入brew_install.rb保存的路径，在终端输入指令

ruby brew_install.rb

• 等待安装完成

如何使用

• 安装你所需要的包

brew install <packageName>
brew install react-native-cli

• 卸载包

brew uninstall <packageName>

• 查询可用包

brew search <packageName>

• 查看已安装包列表

brew list

• 更新Homebrew

brew update

• Homebrew帮助信息

brew -h

• 其他brew命令

brew install git // 使用brew安装软件
brew home   // 用浏览器打开brew的官方网站
brew info   // 显示软件信息
brew deps   // 显示包依赖

brew和brew cask区别

• brew 装的主要是 command line tool
• brew cask主要用来下载一些带界面的应用软件，下载好后会自动安装，并能在mac中直接运行使用
