idea builds golang environment

As a simple, efficient and parallel programming language, Go language has attracted much attention in recent years and is increasingly favored by developers. If you are a Go language developer, in order to develop better, you must build an environment suitable for your own development. Next, let’s introduce how to build a Go language development environment.

1. Installing Go

First, you need to install Go on your local computer. Before installing Go, you need to go to the Go language official website (https://golang.org/) to download the latest version of the Go installation program.

After downloading, double-click the installer and follow the prompts to complete the installation. The installation directory will default to "C:Go", you can also choose other directories for installation.

2. Set environment variables

After the installation is complete, you need to add the bin directory of the Go language to the system PATH environment variable. This will make it easier for you to access the environment in any directory. You can run the go command.

Press the Win R key to open the run window, enter "sysdm.cpl" and press Enter to enter the "System Properties" window, click the "Advanced" tab, and then click the "Environment Variables" button.

In the "Environment Variables" window, find the "Path" option in "System Variables", click the "Edit" button, click the "New" button in the pop-up dialog box, and enter the bin directory of the Go language path (such as "C:Go in"), then click the "OK" button to save your changes.

3. Configuration Editor

Go language development can use a variety of editors, among which the more popular ones are: Visual Studio Code, Sublime Text, Atom, etc. Here, we take Visual Studio Code as an example.

First open the Visual Studio Code editor, select "Extensions" in the sidebar, then search for the "Go" plug-in, download and install it.

After the installation is complete, open a Go language project in the Visual Studio Code editor, and then a prompt box will pop up in the lower right corner, prompting you whether you need to install Go language-related tools and libraries. Just click the "Install" button.

4. Create project

After completing the above environment configuration, you can create a Go language project. First, you need to open the command line in the directory where you want to save the project. Then enter the following command:

go mod init <项目名>

At this time, the Go language will create a go.mod file in the current directory for modular management of the project. In this file, you can add relevant dependencies and version information.

Create a main.go file in the project directory, and then enter the following code:

package main

import "fmt"

func main() {
    fmt.Println("Hello Go")
}

Run the following command to compile and run:

go run main.go

At this point, you have successfully built A Go language development environment was created.

Summary

Go language is a powerful and lightweight language with the advantages of high concurrency, high efficiency, simplicity, etc., so it has always been favored by developers. Before developing a Go language project, you need to set up a development environment, including installing Go language, setting environment variables, configuring the editor, and creating projects. I believe that through the introduction of this article, you have a deep understanding of the construction of Go language development environment.
