windows安装
下载安装
Go官网下载地址：https://golang.org/dl/
由于网络问题大家可能打开有些慢，或者下载失败。大家也可以从下边下载。
下载执行后大家直接一路下一步就行了。
配置环境变量
（win+pause打开设置）--> 高级设置 --> 高级 --> 环境变量 
配置GOPATH；他是用来存放你项目工程代码的地方。
然后将GOPATH 和 go安装的路劲配置到path中。
然后通过cmd执行go version查看版本，当看到版本后证明安装成功。
创建工程目录
在我们GOPATH中创建 bin pkg src
开发工具
go语言的开发工具有很多，这个根据个人的喜好进行选择。vscode、goland 、IntelliJ + Go 插件、LiteIDE等都行。他就是一个工具不用太纠结。
vscode+go插件
mac和window安装一样的。去官网下载https://code.visualstudio.com/download
在vscode中搜索go，然后安装。为了方便使用你可以先安装一个中文插件。
安装成功后在安装go语言开发工具安装包(代码提示，代码自动补全等功能)。
shift+ctrl+p 然后输入go:install选择Go:Install/Update Tools
全选，然后安装。

原因是网络问题。懂得都懂。我们只需配置一下国内的代理重新下载安装一下插件就好了。
