How to set up Golang development environment on win system

Golang is an open source programming language whose source code is hosted on GitHub. Before writing a Golang program, we need to set up a Golang development environment locally to develop, test, compile and deploy Golang applications. This article will introduce how to build a Golang development environment on the Windows operating system.

Step 1: Download Golang

First, we need to download Golang from the Golang official website (https://golang.org/dl/). Click the download link and select the binary that matches your operating system. Download the Windows Installer (.msi) file on Windows and double-click to run the file to install.

Step 2: Set Golang environment variables

By default, Golang will be installed in the C:\Go directory. We need to add the Golang bin directory path to the system environment variable PATH so that Golang related commands can be used directly on the command line.

Open the system environment variable setting interface, select the "Environment Variables" option, then find the PATH variable under "System Variables" and click Edit. Add the Golang bin directory path at the end of the variable value (for example, C:\ Go\bin) and click OK to save the settings.

Step 3: Verify Golang installation

After completing the above settings, we open the command line window, enter the following command and press Enter:

go version

If in the command line Seeing the version information of Golang means that Golang has been successfully installed.

Step 4: Create a Golang working directory

Before developing a Golang application, we need to create a dedicated working directory so that the Golang application and related files can be created in this directory. We can create a directory anywhere suitable and name it "gowork".

Step 5: Create the first Golang program

Now, we enter the "gowork" directory and create a file named "hello.go" in this directory. Enter the following content in the file:

package main

import "fmt"

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

After saving the file, enter the "gowork" directory in the command line window, enter the following command and press Enter:

go run hello.go

If the command The output result of the line is "Hello, world!", which means that the first Golang program has been successfully run.

Step 6: Use Golang development tools

In addition to manually creating and writing Golang applications, we can also use various integrated development environments (IDEs) and editors to improve development efficiency. IDEs such as Visual Studio Code and GoLand can help developers write and debug Golang applications more quickly.

Summary

This article introduces the basic steps to build a Golang development environment on the Windows operating system. Through these steps, we can successfully install Golang, set Golang environment variables, create a Golang working directory, create the first Golang program, and use Golang development tools, etc. I hope it will be helpful to developers who are new to Golang.
