Let's take a look at how to build a Golang environment

Among the choices of modern programming languages, Golang language has gradually become the first choice for many programmers. The Golang language has the advantages of efficiency, lightweight, and security, and can help programmers develop applications faster and more efficiently. Next, let’s take a look at how to set up a Golang environment.

1. Download Golang

First, we need to download Golang from the official website. The download URL is: https://golang.org/dl/. After opening the website, we can see all Golang versions. Select the latest version, and then download the corresponding installation package according to your machine's operating system. Just follow the website prompts to complete the Golang installation.

2. Set Golang environment variables

After installing Golang, we need to set Golang environment variables. Open the system environment variable settings, then find the "Path" variable in "System Variables" and add the installation path of Golang in it. For example, if the installation path is "C:\Go", then add "C:\Go\bin" to "Path". After the settings are completed, you can use Golang related commands in the command line window.

3. Verify that Golang is installed successfully

Open the command line window and execute the "go version" command to see the version information of Golang.

4. Build the Golang development environment

Next, we need to install some tools to build the Golang development environment.

(1) Install Git tool

In the command line window, enter the "git" command. If the prompt cannot find the command, you need to install the Git tool.

(2) Install Visual Studio Code editor

Visual Studio Code is a very excellent editor that can help us develop Golang applications more efficiently. We can download the VS Code editor from the official website. The download URL is: https://code.visualstudio.com/Download. After downloading, install and use.

(3) Install the Go plug-in

Open the installed Visual Studio Code editor, select "Extensions" in the left menu bar, then search for the "Go" plug-in, and install the plug-in. Can.

5. Write the first Golang program

After the installation is completed, we can write the first Golang program.

Create a new folder in Visual Studio Code, such as "hello", and then create a file named "main.go" in the folder with the following content:

package main

import "fmt"

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

Next, enter the "hello" folder in the command line window and execute the "go build" command to compile the program executable file "hello.exe". Finally, run the executable file in the command line window, and you can see the "Hello, world!" information output.

6. Summary

The above is a detailed description of how to set up a Golang environment and write the first Golang program. Through the above steps, I believe everyone can easily get started with Golang development. Golang language is a very excellent programming language and will have wide application prospects in future software development.
