1. 使用VS Code安装GO环境

        百度下载go安装包安装之后，比如我本地是安装在D:\program files\Go目录，此时需要将系统的环境变量更改为此目录，因为环境变量中默认填写的是C:\Users\Administrator\go，但是这个目录下并没有什么东西，导致在VS中运行的时候会报错。修改之后没生效可以试试重启电脑。

        第一次运行的时候VS会提示下载GO的插件，默认的proxy设置是

GOPROXY=https://proxy.golang.org/

但是这个地址国内访问有问题，下载的时候会报错如：

Installing github.com/fatih/gomodifytags@latest FAILED

所以需要修改为：

GOPROXY=https://goproxy.io/

在windows的命令行中（cmd）进行修改，修改使用的命令为：

go env -w GOPROXY=https://goproxy.io/,direct

修改完成之后重启VS即可正常下载插件了，插件安装成功之后有如下提示：
