Install Golang on Ubuntu using Snap
December 28, 2021
This is a short tutorial to install Golang on Ubuntu using Snap.
Overview
In this tutorial, we will first install Golang on Ubuntu using Snap. Then we will test our setup using a simple program.
Prerequisites
- Ubuntu
- Snap
Installation
Let’s install Golang first.
sudo snap install go –classic
Once the installation is done, we can check the installation with the following command.
go version
You will see something like this on your terminal go version go1.17.5 linux/amd64
Dependency
In order to install other libraries and to keep track of your dependencies, you need to create a mod file.
First, let’s create a project folder.
mkdir MyGoProject
cd MyGoProject
Inside the folder, just run the following command on the terminal. Here, we are creating MyFirstProject as a module. For better module naming, you can follow this link from Golang Website.
go mod init MyFirstProject
This will create a go.mod file inside the folder. If you open it, you will see your module name as MyFirstProject.
Code
Let’s write our first hello world program. Inside the same folder, create a file name called main.go and paste the following code.
package main
import "fmt"
func main() {
fmt.Println("Hello, World!")
}
After you save the file, run the following command.
go run main.go
You will see our hello world message as Hello, World!
Side Note: If you are using vscode to edit, make sure you add the following setting in your vscode. Refer to this link for more info.
"go.alternateTools": { "go": "/snap/go/current/bin/go" },
