Guide to setting up the Golang operating environment under Mac system

Golang, also known as the Go language, is an open source programming language developed by Google. It has the characteristics of high concurrency, fast compilation speed, and complete tool chain, so it is very popular in the field of software development. If you are a Mac user and want to set up a Golang running environment on a Mac system, the following guide will help you complete the process.

Step 1: Download Golang

First, you need to download the Golang installation package for Mac system from the official website https://golang.org/dl/. Choose the installation package appropriate for your Mac version, which is usually provided in .pkg format.

Step 2: Install Golang

After the download is complete, double-click the Golang installation package to install. Follow the installation wizard prompts to install Golang into the directory of your choice. After the installation is complete, you need to configure Golang’s environment variables.

Open a terminal window and enter the following command to edit the ~/.bash_profile file:

$ nano ~/.bash_profile

Add the following content at the end of the file:

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

Save and exit the editor. Next, load the modified environment variable configuration:

$ source ~/.bash_profile

Step 3: Verify Golang installation

Enter the following command in the terminal to check the Golang version information to verify whether the installation is successful:

$ go version

If the Golang version number is successfully displayed, it means the installation is correct.

Step 4: Write and run a simple Golang program

Next, let’s write a simple Hello World program to verify the setup of the Golang operating environment.

Create a new file named hello.go and enter the following code:

package main

import "fmt"

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

After saving the hello.go file, enter the directory where the file is located in the terminal and enter the following command to run Program:

$ go run hello.go

If "Hello, Golang!" is successfully output, it means that you have successfully built and run the Golang program.

Conclusion

Through the above steps, you have successfully set up the Golang operating environment on the Mac system, and successfully written and run a simple Golang program. I hope this guide can help you start developing with Golang smoothly, and I wish you more achievements in learning and practice!
