mac home brew install go

mac利器home brew安装Go

首先你得需要安装home brew和ruby环境（因为home brew依赖ruby） 

如果没有请自行到链接安装

准备好之后就开始安装go了

brew update && brew upgrade
brew install git
brew install mercurial
brew install go

安转go之后还需要配置环境变量

vim ~/.bash_profile  or vim ~/.bash_profile

#GOROOT
export GOROOT=/usr/local/Cellar/go/1.7.4/libexec

#GOPATH
export GOPATH=$HOME/GoLang

#GOPATH bin
export PATH=$PATH:$GOPATH/bin

#GOPATH root bin
export PATH=$PATH:$GOROOT/bin

source ~/.bash_profile or source ~/.bash_profile

ok go环境配置完毕，接下来输入go env即可看到go的详细信息
