Golang is a powerful programming language that performs well in developing Web, network and other applications and is widely used in various business scenarios. In this article, we will introduce how to set up a Golang environment so that you can start using and learning this popular language.

1. Installing Golang

First, you need to download Golang’s binary installation package from the official website, or install it from your Linux distribution’s repository. If you are using macOS, you can also install it using the brew package manager.

After the installation is complete, you need to set some environment variables so that the system can find the Golang executable file. Add the following lines in the ~/.bashrc or ~/.zshrc file:

export PATH=$PATH:/usr/local/go/bin
export GOPATH=$HOME/go
export PATH=$PATH:$GOPATH/bin

The first line is to add the Golang executable file path to the system environment variable. The second line is to set GOPATH, which is the working directory of your project, which contains all source code, executable files, etc. The third line adds your $GOPATH/bin folder to your PATH. This folder contains the tools and commands you use while developing.

2. Editor and plug-in

Golang needs a good editor when developing, which can provide syntax highlighting, code completion, automatic formatting and quick navigation, etc. Function. The following are some commonly used editors and plug-ins:

• VS Code: a popular cross-platform editor with a large number of plug-ins available, including Go plug-ins that can provide you with function navigation, code formatting ization and other functions.
• Sublime Text: Another popular cross-platform editor, it also has a Golang plugin.
• Vim and Emacs: Both Vim and Emacs have rich plug-ins and configuration options for you to choose from.

3. Environment Testing

Now that you have installed Golang and selected your editor, we need to test your environment before starting development.

Run the following command in the console:

$ go version

If your Golang environment is installed correctly, you should see output similar to the following:

go version go1.15.2 linux/amd64

Next, we will create a test program and run it to test whether your environment is working properly.

Enter the following command in the terminal:

$ mkdir -p $HOME/go/src/github.com/YOUR_USERNAME/hello

Next, create $HOME/ go /src/github.com /YOUR_USERNAME/hello/hello.go file and add the following content:

package main

import "fmt"

func main() {

fmt.Println("Hello, world!")

}

Save the file and enter the following command in the terminal:

$ go run hello.go

If no errors are output later message, you should be able to see the following output:

Hello, world!

This indicates that your Golang environment has been installed and set up correctly and you can start using it.

4. Find resources and learn

When learning Golang, it is very important to find tutorials and resources. Here are some resources for learning Golang:

• Golang official documentation: If you want to learn more about Golang, the official documentation is a good starting point. It contains the language specification, standard library, practice guide and some Useful examples.
• Go by Example: This website has many concise examples to help you get started with Golang quickly.
• Golang Bridge: This website provides a helpful community and learning resource, including articles, tutorials, and code samples.

Summary

In this article, we introduced the steps to build a Golang environment. By installing Golang and setting the GOPATH and environment variables, we can start writing and running Go programs. We also discussed some commonly used editors and plugins, as well as some resources for learning Golang. Now you can start exploring this popular programming language and using it in your own projects.
