How to install Golang environment under Windows system

In recent years, Golang (also known as Go) has become a popular programming language. As a language that combines advantages such as performance, multi-threading, and high concurrency, Golang has also been widely used in fields such as web development and backend server development. This article mainly describes how to install the Golang environment under Windows systems.

1. Download the installation package

First, we need to download the Golang Windows installation package from the official website. The download address is https://golang.org/dl/. Select the version corresponding to the platform as needed. Here we take Windows 64-bit as an example.

2. Install Golang

After the download is completed, double-click the installation package to install it. In the pop-up installation interface, click "Next" to proceed to the next step.

In the next interface, you can select the installation path of Golang and the installed components. If it is only used as a local development environment, just keep the default.

After clicking "Next", you will be prompted to start the installation. Wait a moment to complete the installation of Golang. After the installation is complete, we need to configure relevant environment variables to use Golang normally.

3. Configure environment variables

First, open "My Computer", right-click "Properties" and enter "Advanced System Settings".

In the opened interface, click the "Environment Variables" button. Find "Path" in "System Variables" below and double-click to edit it.

In the editing interface, add the installation path of Golang, such as "C:\Go\bin". The variable value can be appended directly, and multiple paths are separated by ";".

4. Verify the installation

After completing the configuration, we can enter the following command on the command line to verify whether the installation is successful:

go version

If the Golang version information is correctly output, then Indicates that the installation is successful.

5. Code running

After the installation is completed, we can start using Golang to write programs. Open an editor, such as VS Code, and write the following code:

package main

import "fmt"

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

Save the file as "main.go", use the command line to enter the directory where the file is located and execute the following command:

go run main.go

If everything goes well , the "Hello World!" message will be output in the console.

6. Summary

The above are the methods and steps for installing Golang under Windows system. Through the above operations, we can easily develop and test Golang locally. Finally, we need to note that the documents and standard libraries provided on the Golang official website are all in English, so developers from non-English speaking countries need to read and learn patiently.
