Golang is an open source programming language developed by Google. Its design goal is to improve programming efficiency and reliability. Installing Golang allows developers to easily develop Golang applications on Mac systems. This article will detail how to install Golang on Mac.

Here are the steps to install Golang on Mac:

Step 1: Download the Golang binary

First, you need to go to Golang’s official website Website to download Golang binaries for Mac systems. On this page, you will see a list, select your system version and click the corresponding download link.

Step 2: Install Golang

After the download is completed, you can find an installation file named go1.x.x.darwin-amd64.pkg, where x.x represents Golang version number. You can double-click the file and follow the prompts to install it. During the installation process, you will need to provide administrator rights.

Step 3: Configure environment variables

After the installation is complete, you need to configure some environment variables to use Golang in the terminal. Open the terminal application (Applications -> Utilities -> Terminal) and open your .bash_profile file.

Enter the following command to open the file:

open-e.bash_profile

If you do not have a .bash_profile file, you can create a new one:

touch.bash_profile
open-e.bash_profile

In the .bash_profile file, add the following content:

exportGOPATH=$HOME/go
exportPATH=$PATH:/usr/local/go/bin:$GOPATH/bin

Save and close the file.

Step 4: Set the GOBIN environment variable (optional)

GOBIN is an environment variable used to specify the output directory of the Golang executable file. If you wish to save the executable file in a specific directory, you can use the GOBIN environment variable.

Enter the following command in the terminal:

mkdir$GOPATH/bin

Then in the .bash_profile file, add the following content:

exportGOBIN=$GOPATH/bin

Save and close the file.

Step 5: Check whether the installation is successful

Enter the following command in the terminal to check whether Golang is installed correctly:

goversion

If the installation is successful, You will see the version number of Golang.

Step Six: Write and Run Code

Now, you can try to write and run your first Golang program. Create a new file in the terminal, for example "hello.go", and write the following code:

packagemain
import"fmt"
funcmain(){
fmt.Println("Hello,World!")
}

After saving the file, enter the following command in the terminal to run the program:

gorunhello.go

If All goes well and you will see "Hello, World!" output in the terminal.

At this point, you have successfully installed and configured Golang on your Mac. You can start developing applications using Golang. In the process of learning and exploring Golang, you may also find other useful tools and libraries that can further improve your development efficiency and capabilities. I wish you explore the infinite possibilities in the world of Golang!
