如何导入官方的mongodb驱动程序包

Question

How to import official mongoDB driver package in Go?

I am following the official Go-mongoDB-driver package instruction (https://www.mongodb.com/blog/post/mongodb-go-driver-tutorial). I have installed the mongoDB package using this:

go get github.com/mongodb/mongo-go-driver

but I just can't import the package

I am doing a very simple snippet in my main.go

package main

import "github.com/mongodb/mongo-go-driver/mongo

func main() {
}

This gives me:

main.go:8:8: code in directory $GOPATH/src/github.com/mongodb/mongo-go-driver/bson expects import "go.mongodb.org/mongo-driver/bson"

When I tried to import go.mongodb.org/mongo-driver/bson, It gives me this:

main.go:10:8: cannot find package "go.mongodb.org/mongo-driver/bson" in any of:
    /usr/local/go/src/go.mongodb.org/mongo-driver/bson (from $GOROOT)
    $GOPATH/src/go.mongodb.org/mongo-driver/bson (from $GOPATH)

Kindly help, quite new in Go and not sure where to look since I don't find people having this issue a lot.

The error actually gives you the answer: You must use that driver as go.mongodb.org/mongo-driver/bson instead. The package has apparently changed URLs some time in the past, and the tutorial you're referring to has not yet been updated.

You should instead refer to the installation instructions here. In short, do this:

go get go.mongodb.org/mongo-driver/mongo

then import it using the same path:

import (
    "go.mongodb.org/mongo-driver/mongo"
    "go.mongodb.org/mongo-driver/bson"
    // etc
)
