golang offline module dependencies download

Using go mod vendor

0 - With an existing module

• copy go.mod and go.sum files from the offline PC to the internet PC

0bis - New module

• create a folder on the internet PC
• create a go module : go mod init test

1 - Download dependencies via vendor folder

• create a offline_modules.go file :

package offline_modules

func main() {}

• add the dependencies you want to download (use _) :

package offline_modules

import (
	_ "github.com/gorilla/mux"
	_ "github.com/sirupsen/logrus"
)

func main() {}

• run go mod vendor

• the vendor folder should have new folders in it representing dependencies

2 - Back to offline

• copy go.mod, go.sum and vendor
• paste them on your offline PC, edit go.mod module name if necessary
• run your go commands with the flag -mod=vendor like go run -mod=vendor main.go

if you had "no required module provides package" error message:
Run go mod tidy first
then run go mod vendor again
