Take you step by step to configure the Golang environment

Golang is an open source programming language developed by Google and has received widespread attention for its efficient compilation speed and memory management. If you plan to learn or use the Golang programming language, in this article we will take you step by step to configure the Golang environment to make your programming journey smoother.

1. Install Golang

First, you need to download the Golang software package from the official website. Open the https://golang.org/dl/ URL, and you can see Golang installation packages for various operating systems. Select the installation package suitable for your operating system, download and run the installation program.

Note: The installer requires administrator privileges, so on Windows systems, you need to run the installer as an administrator.

2. Configure environment variables

After the installation is complete, you need to configure your system environment variables so that you can access the Golang tool from any location. Please follow these steps:

1. Open your computer's settings, select "System" and then select the "About" tab.

2. In the new window, you will see the name and description of the computer. Find the "Advanced system settings" link and click on it.

3. Open the Advanced tab and click the "Environment Variables" button.

4. In the "Environment Variables" window, find the "PATH" variable in the system variables, and then click "Edit".

5. In the pop-up "Edit Environment Variables" window, click the "New" button and add the "C:\Go\bin" path.

6. Finally, click the "OK" button to save the changes.

3. Test the Golang environment

To test whether the Golang environment is configured successfully, you can open a command line window and enter the command "go version" to verify whether the installation is successful. If the installation is successful, you will see output similar to "go version go1.15.5".

4. Write the Hello World program

To write the first program in Golang, you need to create a new file, then enter the following code, and then save the file as "hello.go" .

package main

import "fmt"

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

This program will print the "Hello, World!" message to the console.

5. Run the program

Now that you have completed writing a simple Golang program, the next step is to run the program. In the command line interface, navigate to the location where you saved the "hello.go" file and enter the following command to run the program:

go run hello.go

If everything goes well, you will see Hello, World! in the console! The result output.

So far, you have successfully installed and configured the Golang programming environment on your computer, and written and run a simple program. I believe that through the guidance of this article, you already have a certain understanding of Golang. If you want to continue learning Golang and use it to develop more applications, then start now!
