将pubsub与golang一起使用：ocgrpc.NewClientStatsHandler

Question

I am following this tutorial to publish a topic to Pub/Sub from a golang project and here's the code I have for that project at the moment:

package main

import "cloud.google.com/go/pubsub"
import "fmt"

func main() {
    fmt.Printf("hello, world
")
}

All it does is simply imports the pubsub but when I run go get I get this error: undefined: ocgrpc.NewClientStatsHandler

C:\Users\iha001\Dev\golang-projects\src\github.com
aguibihab\golang-playarea\src\gcloud>go get
# cloud.google.com/go/pubsub
..\..\..\..\..\cloud.google.com\go\pubsub\go18.go:34:51: undefined: ocgrpc.NewClientStatsHandler

Is there anything else I need to install to get this running?

It seems to have been an issue on the repo:

@naguibihab This is NOT a windows issue. This commit fixes the problem be072a5. Short explanation: breaking changes where pushed on a minor release of a google pubsub dependency: census-instrumentation/opencensus-go@ac82455, method NewClientStatsHandler was deleted. (They don't claim anywhere they comply with semver).

Here's the fix mentioned in that comment: https://github.com/GoogleCloudPlatform/google-cloud-go/commit/be072a5d1d73144ae0ce1071e9bd43d1ad221581
