How to install Golang on Win8 system

As the title states, how to install Golang on Win8 system requires specific code examples

Go language (Golang) is an open source programming language developed by Google and is highly efficient. performance and powerful concurrency features. Installing Golang on Windows systems and configuring environment variables is the first step for developers to get started with Golang programming. This article will introduce in detail how to install Golang and configure environment variables on Windows 8 systems.

Installation steps:

1. Download the Golang installation package

First, open the Golang official website https://golang .org/, click the "Download" button on the homepage. On the download page, select the installation package suitable for Windows systems, and select the 32-bit or 64-bit installation package to download according to the number of bits of the system.

2. Install Golang

After the download is complete, run the installation package and follow the installation wizard’s prompts to install. You can customize the installation directory. It is recommended to choose the root directory of drive C or other system disks for installation.

3. Verify the installation

After the installation is complete, enter the following command in the command prompt to verify whether Golang is installed successfully:

go version

If the Golang version information is output, it means the installation is successful.

Configure environment variables:

1. Add GOROOT environment variables

Open "Computer"->right-click "Properties" ”->Click “Advanced System Settings”->Click “Environment Variables”->Click “New” in “System Variables”:

Variable name: GOROOT
Variable value: C: Go (Golang installation path) 

2. Add the GOPATH environment variable

Also click "New" in "System Variables":

Variable name:GOPATH
Variable value: C:Goworkspace (customize the working directory of the Golang project)

3. Update the Path environment variable

Find the Path variable in "System Variables" and double-click it Edit, add at the end of the variable value:

;%GOROOT% in;%GOPATH% in

4. Verify the configuration

in Enter the following command in the command prompt to verify whether the environment variable configuration is successful:

go env

If the path information of GOROOT and GOPATH is output, the configuration is successful.

Create and run the Hello World program:

1. Create the project directory

Create it in the working directory specified by GOPATH A new directory, for example:

mkdir C:Goworkspacehello

2. Create the main.go file

Create a main in the hello directory. go file, enter the following code:

package main

import "fmt"

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

3. Run the program

Switch to the hello directory in the command prompt and enter the following command to run the program:

go run main.go 

If "Hello, World!" is successfully output, it means that the program runs successfully.

Through the above steps, you have successfully installed Golang on Windows 8 system and configured environment variables. Now you can start developing with Golang! Happy programming!
