Getting go module issue

Question

I'm new to go modules, I'd like to https://github.com/microsoft/ApplicationInsights-Go but can't import it using go modules, all the other packages are automatically imported, just this one doesn't want:/

What am I missing?

package logger

import (
    "fmt"
    "github.com/microsoft/ApplicationInsights-Go/appinsights" //<-- This won't import
)

var tc appinsights.TelemetryClient

func init() {
    tc = appinsights.NewTelemetryClient("")
}


func LogError(err error) {
    if err != nil {
        fmt.Println(err)
        tc.TrackException(err)
    }
}

func LogEvent(message string) {
    ex := appinsights.NewEventTelemetry(message)
    tc.Track(ex)
}

Compiler message:

could not import github.com/microsoft/ApplicationInsights-Go/appinsights (no package for import github.com/microsoft/ApplicationInsights-Go/appinsights)

EDIT 1: GO ENV output

Interesting that it worked for you, when I did go mod init it found all packages, when I do manually go get [github.com/microsoft/ApplicationInsights-Go/appinsights] it's being found but I thill can't use it.

Only

github.com/microsoft/ApplicationInsights-Go

is being imported so when in the logger.go file I'm importing

github.com/microsoft/ApplicationInsights-Go/appinsights

it doesn't see

appinsights

part so I can't use it.

I just copied your code and created a module:

 ~/awesomeProject  go mod init example.com
go: creating new go.mod: module example.com

 ~/awesomeProject  go mod tidy
go: finding module for package github.com/microsoft/ApplicationInsights-Go/appinsights
go: downloading github.com/microsoft/ApplicationInsights-Go v0.4.3
go: found github.com/microsoft/ApplicationInsights-Go/appinsights in github.com/microsoft/ApplicationInsights-Go v0.4.3
go: downloading code.cloudfoundry.org/clock v0.0.0-20180518195852-02e53af36e6c

Could you please paste here your go env output?
