1. 安装Golang (略）
2. 安装VS Code (略）
3. 设置环境变量(source ~/.bash_profile)

export GOROOT='/usr/local/go'
export GOARCH='amd64'
export GOOS='darwin'
export GOPATH='/Users/your_name/gopath'
export PATH='/bin:/sbin:/usr/bin:/usr/local/bin:/usr/local/go/bin'

4. VSCode 安装扩展（略）

5. 执行如下脚本 （执行脚本前，就确保环境变量生效 source ~/.bash_profile)

#!/bin/bash

BASEDIR="$GOPATH/src/golang.org/x"

echo "BASEDIR >> $BASEDIR"

if [ ! -d $BASEDIR ];then
        mkdir -p $BASEDIR
        echo "create $BASEDIR"
fi

cd $BASEDIR
if [ ! -d "$BASEDIR/tools" ];then
        git clone https://github.com/golang/tools
else
        cd $BASEDIR/tools
        git pull
fi
