Mac使用终端安装Homebrew(brew)

Homebrew简称brew,OSX上的软件包管理工具，在Mac终端可以通过brew安装、更新、卸载软件。

1、打开终端直接输入下面指令回车:

1. //
2. ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install)"
3. //

注意：如果当前的用户是管理员，需要对权限进行许可，在执行上面的指令前先执行：sudo chmod -R g+w /usr/local

2、在1中指令回车后会提示“Press RETURN to continue or any other key to abort”(回车继续或者按其他键终止)，这是直接回车进入“Downloading and installing Homebrew...”，如果网络不好的话可能会提示“fatal: unable to access 'https://github.com/Homebrew/brew/': SSLRead() return error -9806...等”，没关系重新输入1的指令更新。

3、更新完成后的提示如下图所示：

4、常用的三条语句搜索(search)、更新(install)、卸载(remove)

搜索：brew search SoftwareName

更新：brew install SoftwareName

卸载：brew remove SoftwareName

（SoftwareName 是你需要处理的软件名）

5、下面是我安装时的过程代码（仅供参考）：
