How to activate Golang on your own computer

Golang activation method:

Golang, also known as Go, is a programming language that has received more and more attention since it was designed. Go has many advantages over other programming languages, such as faster compilation speed, powerful concurrency and flexible syntax. If you are still new to learning and using Golang, then you may not know how to activate Golang on your computer. Then this article will explain to you in detail how to activate Golang.

Step One: Install Golang

Before activating Golang, you first need to install Golang on your computer. You can go to the Golang official website (https://golang.org/) to download the installation program. You can see the "Download Go" button on the homepage of the website. Click it and select the operating system version that suits you to download. After the download is complete, just follow the prompts to install it.

Step 2: Set environment variables

After the installation is complete, you need to configure the environment variables before you can use Golang for programming. Open the terminal of your computer and enter the following command:

Linux/Mac:

export PATH=$PATH:/usr/local/go/bin

Windows:

set PATH=%PATH%;C:\Go\bin

The above two commands will add the Golang installation path to the environment respectively. in variables. If your installation path is not the above path, please replace the corresponding path in the command with your Golang installation path.

Step 3: Verify installation

Before activating Golang, you need to verify whether Golang has been successfully installed. Enter the following command in the terminal:

go version

If you successfully installed Golang, you will see output similar to the following:

go version go1.16.6 linux/amd64

This indicates that your Golang has been installed successfully and you can proceed to the next step. .

Step 4: Activate Golang

Now, you can activate Golang. Enter the following command in the terminal:

go env -w GO111MODULE=on

This command will set the environment variable and enable Go Modules. Go Modules is a package management mechanism introduced in Golang 1.11 and higher, which allows you to easily manage dependencies during the development process. If you want to turn off Go Modules, you can execute the following command:

go env -w GO111MODULE=off

Step 5: Test

Finally, you can test whether Golang has been activated by writing a simple Hello World program. Enter the following command in the terminal:

mkdir hello
cd hello
echo "package main\n\nimport \"fmt\"\n\nfunc main() {\n    fmt.Println(\"Hello, World!\")\n}" > hello.go
go run hello.go

The above command will create a directory named hello on your computer and create a new file named hello.go in it. This file contains a simple Hello World program. Finally, the command "go run hello.go" will run the program and print "Hello, World!".

Through this Hello World program, you can verify that Golang has been successfully activated. Congratulations on completing the activation of Golang.

Summary

This article details how to activate Golang on your own computer. By following the above steps, you can easily activate your own Golang and start your Golang programming journey. Golang has quickly become one of the development languages ​​for many developers due to its speed, performance and scalability. I hope this article can help you better take advantage of Golang.
