cannot find package "github.com/lithammer/shortuuid/v3"

[Marcos]

Hello
I tried the example on README:

package main

import (
    "fmt"

    "github.com/lithammer/shortuuid/v3"
)

func main() {
    u := shortuuid.New() // Cekw67uyMpBGZLRP2HFVbe
}

When I run:

go get -t -v ./...

I got this error:

github.com/lithammer/shortuuid (download)
cannot find package "github.com/lithammer/shortuuid/v3" in any of:
	/usr/local/go/src/github.com/lithammer/shortuuid/v3 (from $GOROOT)
	/home/marcos/go/src/github.com/lithammer/shortuuid/v3 (from $GOPATH)

but the package is available in: /home/marcos/go/src/github.com/lithammer/shortuuid

what was my mistake?

What version of Go are you using and what's the output of go env?

Hi!

go version:

go version go1.16 linux/amd64

and go env output:

I found the problem. I was trying with the GO111MODULE=off

[Peter Lithammer]

Great! I'm gonna close this because I'm reluctant to spend time supporting GO111MODULE=off. But I suspect that you could maybe just change the import path like this to get it working:

 import (
     "fmt"

-    "github.com/lithammer/shortuuid/v3"
+    "github.com/lithammer/shortuuid"
 )
