CSV-TK Tutorial: Go Language Installation Guide

Go language is an open source programming language developed by Google and is widely used to develop efficient, reliable and concise software. This tutorial explains how to install the Go language on your computer and provides some concrete code examples to help you get started quickly.

Step one: Download the Go language installation package

First, you need to visit the Go language official website (https://golang.org) and download the Go language installation package suitable for your operating system , select the corresponding version to download, usually there are Windows, Mac and Linux versions to choose from.

Step 2: Install Go language

After the download is completed, install it according to the operating system type. In Windows system, double-click the downloaded installation file and follow the prompts to install; in Mac system, open the .dmg file and drag and drop the Go language application into the Applications folder; in Linux system, unzip the downloaded installation package and Just copy the decompressed folder to the specified directory.

Step 3: Configure Go language environment variables

In order to use Go commands on the command line, you need to configure Go language environment variables. In the Windows system, right-click "My Computer" to enter "Properties", click "Advanced System Settings", click "Environment Variables" in the pop-up window, create a new variable named "GOPATH" in the system variables, and Enter the installation path of the Go language as the value; on Mac and Linux systems, use an editor in the terminal to open the .bash_profile or .zshrc file and add the following content:

export GOPATH=/path/to/your /gopath
export PATH=$PATH:/path/to/your/gobin

Remember to replace "/path/to/your/gopath" with your Go language installation path.

Step 4: Verify Go language installation

Open the command line window and enter the following command to verify whether Go language is successfully installed:

go version

If you see the Go language version information output, the installation is successful.

Step 5: Write and run the first Go program

Now, let’s write a simple Go program and run it. Create a new file, name it hello.go, and enter the following code:

package main

import "fmt"

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

After saving the file, enter the directory where the file is located on the command line, and enter the following command to compile and run the program:

go run hello.go

If you see "Hello, World!" output, you have successfully written and run your first Go program.

Through this tutorial, you have successfully installed the Go language and written and run a simple program. I hope these specific code examples can help you better understand the basics of the Go language and lay a good foundation for future learning and development. Happy studying!
