Go is a new programming language developed by Google, also known as Golang. It is an open source, efficient, and powerful programming language suitable for large-scale distributed system development. This article will provide a simple Golang installation tutorial to help you easily install and start using Golang.
Before starting the installation process of Golang, you need to download Golang first. You can find the corresponding download link on the Golang official website (https://golang.org/dl/) and download the executable file according to your computer operating system. When downloading, you should select the latest version to ensure that you are using the latest version of Golang.
Before installing Golang, you need to first check whether your computer has Golang installed. In the terminal or command prompt, enter the following command to check whether Golang has been installed.
go version
If you have not installed Golang, you can install Golang by following the steps.
On Windows systems, you can double-click the downloaded executable file and follow the prompts to install;
On macOS systems, you can download the Golang. Double-click the pkg file to open it, and then install it according to the prompts. When the installation interface appears, you can click the "Continue" button as prompted.
On Linux systems, you need to use the package management tool for installation. For example, on Ubuntu or Debian systems, you can use the apt-get command to install.
sudo apt-get install golang
After the installation is complete, you can run the "go version" command again in the terminal or command prompt to verify whether Golang has been successfully installed.
In order to use Golang, you need to set some necessary environment variables.
On Windows systems, you can set environment variables by following the steps below.
Click the "Start" button, then right-click the computer icon and select the "Properties" option. Then, in the new window, click the "Advanced system settings" button.
In the "System Properties" window, click the "Environment Variables" button.
In the "Environment Variables" window, find the "System Variables" area and find the "Path" variable. Click on the variable and then click the Edit button.
In the edit variable dialog box, click the "New" button and enter the installation path of Golang.
Click the "OK" button and then close all open windows.
On macOS systems, you can set environment variables by following the steps below.
Open the terminal and enter the following command.
nano ~/.bash_profile
This command will open a blank file where you can set environment variables.
Add the following lines to the file:
export PATH=$PATH:/usr/local/go/bin
Press the "Ctrl X" key, then save the file and exit.
In Linux systems, the steps you can take to set environment variables are similar to macOS systems. You can open and edit the .bashrc file with the following commands.
nano ~/.bashrc
Add the following lines in the file.
export PATH=$PATH:/usr/local/go/bin
Press the "Ctrl X" key, then save the file and exit.
After installing and setting the Golang environment variables, you can test whether your Golang has been successfully installed. In a terminal or command prompt, enter the following command to create a simple "Hello World" program.
package main
import "fmt"
func main() {
fmt.Println("Hello, World!")
}You can copy the above code into your editor and save the file into the hello.go file. Then, go back to the Terminal or Command Prompt, go to the directory where the file is located, and enter the following command.
go run hello.go
If you see the output "Hello, World!", your Golang has been successfully installed and set up, and you are ready to program with it.
Summary
With the Golang installation tutorial provided in this article, you should be able to easily install and start using Golang. Golang is a fast, efficient, and powerful programming language, especially suitable for the development of large-scale distributed systems. Try learning Golang and start writing your own code!
