为什么我无法为docker获取go sdk?

I am trying to run docker go SDK example file. I am quite new to Go language; I am not sure how to run below docker SDK API code. But I tried somehow; please help me with below error.

When I tried to run this go run example-ps.go

example-ps.go - content is below

package main

import (
  "io"
  "os"

  "github.com/docker/docker/client"
  "github.com/docker/docker/api/types"
  "github.com/docker/docker/api/types/container"
  "golang.org/x/net/context"
)

func main() {
  ctx := context.Background()
  cli, err := client.NewEnvClient()
  if err != nil {
    panic(err)
  }

  _, err = cli.ImagePull(ctx, "docker.io/library/alpine", types.ImagePullOptions{})
  if err != nil {
    panic(err)
  }

  resp, err := cli.ContainerCreate(ctx, &container.Config{
    Image: "alpine",
    Cmd:   []string{"echo", "hello world"},
  }, nil, nil, "")
  if err != nil {
    panic(err)
  }

  if err := cli.ContainerStart(ctx, resp.ID, types.ContainerStartOptions{}); err != nil {
    panic(err)
  }

  if _, err = cli.ContainerWait(ctx, resp.ID); err != nil {
    panic(err)
  }

  out, err := cli.ContainerLogs(ctx, resp.ID, types.ContainerLogsOptions{ShowStdout: true})
  if err != nil {
    panic(err)
  }

  io.Copy(os.Stdout, out)
}

I am getting below error. How do I import those library files?

    if you have golang installed correctly just issue this in the dir where your golang code lives

    go get -v -t ./...
    

    which will install the upstream libraries ... then you can compile your code ... for details issue

    go help packages
    

    the short of it is ./... will install all packages [ and recursively its upstream packages, etc, etc.] mentioned in any go file's import in your current dir

    If you have ever spent days manually installing upstream libraries for any other language you will appreciate how much of a lifesaver this really is
