为什么构建约束排除了“ /Users/rpurusho/go/src/google.golang.org/api/compute/v1”中的所有Go文件？

I am trying to write a program in Go and I see the above error when I try to import a library from google.golang.org/api/compute/v1

Given below is the code snippet..

package main

import (

    "log"
    "fmt"
    "context"

    "cloud.google.com/go/storage"
    "google.golang.org/api/iterator"
    "google.golang.org/api/option"

    _ "google.golang.org/api/compute/v1"

)

Does anyone know what this issue might be?
