Install golang tutorialMay 05, 2023 pm 09:35 PM

In recent years, Golang has been developing rapidly and is used in more and more projects. If you want to learn Golang, then installing Golang is a necessary step. This article will provide a simple and easy-to-understand installation tutorial for Golang to help you quickly start your Golang journey.

Step One: Download Golang

First, visit the official Golang download page (https://golang.org/dl/). In this page, you can choose different operating systems and architectures. Choose the operating system and architecture that suits you and click the download button.

Golang’s installation package is a compressed file. Once the download is complete, unzip the file to the appropriate location. For Windows users, you can unzip the compressed package to the C:\Go directory, and then add C:\Go\bin to the environment variable. For Linux and Mac users, you can unzip the compressed package to the /usr/local directory, and then add /usr/local/go/bin to the PATH environment variable.

Step 2: Verify the installation

After completing the installation, we need to verify whether the installation was successful. Open a terminal or command line and enter the following command:

go version

If the installation is successful, you will see output similar to the following:

go version go1.15.2 darwin/amd64

If you see this output, it means that Golang has been installed It worked. If you get output different from the above, there may be a problem with your installation and you need to check the installation steps.

Step 3: Set up the workspace

Before we start writing Golang applications, we need to set up the Golang workspace. A Go workspace is a directory tree containing three directories:

  • src: source code file
  • pkg: package file
  • bin: executable file

In order to set up the workspace, we can first create a directory as a workspace anywhere. Next, create three subdirectories, src, pkg and bin, in this directory. For example, you can create a workspace named GoWork through the following command:

mkdir GoWork
cd GoWork
mkdir src pkg bin

Please note that this command is to create a complete workspace and does not require us to put the workspace in the same directory as the Golang installation directory. Under contents.

Step 4: Write the first Golang program

Now that we have completed the installation of Golang and the setup of the workspace, the next step is to write the first Golang program. Open your favorite text editor and enter the following code:

package main

import "fmt"

func main() {
    fmt.Println("Hello, World!")
}

Please note that the first line of the code contains the package directive, which is a directive that tells the compiler which package the file belongs to. In this case, the name of the package is main, which is a special name used to instruct the Golang compiler to compile this file into an executable program.

Next, we use the import command to import the fmt package to output the string "Hello, World!". Finally, call the fmt.Println() function in the main function to output this string.

Save your code to the GoWork/src directory and name it main.go. Then, open a terminal or command line and enter the following command:

cd /path/to/GoWork
go build
./main

If everything goes well, you will see the terminal output the string "Hello, World!". At this point, you have successfully written and run your first Golang program.

Summary

In this article, we provide an easy-to-follow tutorial for installing Golang and give the steps to set up a workspace and write your first Golang program. I hope this article can help you get started with Golang quickly. If you want to learn more about Golang, you can refer to the official documentation (https://golang.org/doc/) or other Golang learning resources.
