2.原因
国内FHQ政策，以及Vs Code 中go的第三方扩展库地址不对。
3.解决办法。
以windows为例，
在cmd 窗口中执行下列语句
go env -w GO111MODULE=on
go env -w GOPROXY=https://goproxy.io,direct
如果报go找不到，编辑下Path，或者从官方网站下载golang安装。
然后，在cmd中手动下载第三方扩展库。下载命令如下：
对照以上命令行，替换vs code中报错的那几个包安装。
4.尝试第一个helloworld程序。
在GOPATH下创建helloworld.go程序。GOPATH地址用go env获得。
VSCode---文件---打开文件夹，选择GOPATH目录。建立helloworld.go文件。
内容如下：
package main
import "fmt"
func main() {
fmt.Printf("hello world.")
}
保存重启VsCode，一定要重启VsCode。

成功。
