In recent years, Golang has been accepted and used by more and more developers. Compared with other languages, such as Python and Java, Golang's concurrency performance is very good, so it has become one of the popular languages in the field of cloud computing and containers. This article will introduce how to install Golang on Windows.
First, go to the official website to download the latest version of Golang. Select the Windows system version that suits you on the official website and download it.
When the download is complete, double-click the downloaded .msi file to enter the installation wizard. First read the User Agreement and agree to it. Next, you can choose the installation path, usually the default path is sufficient. Then select "Install" to officially start the installation process.
After the installation is completed, you need to set the environment variable. Enter the system variable setting, find the Path variable, click Edit, and add it in the variable value column. The installation path of Golang, separated by ";". For example, assuming your installation path is "C:\Go", you should add ";C:\Go\bin" at the end of the variable value.
After completing the above steps, we need to confirm whether Golang is successfully installed. Open the command prompt and enter in the command line:
go version
If the currently installed Golang version is displayed, the installation is successful.
After the installation is completed and confirmed to be successful, we can start writing the first Golang program. Open the code editor, create a new "hello.go" file, and enter the following content in it:
package main
import "fmt"
func main() {
fmt.Println("Hello Golang!")
}In the code, "package main" means that this program is a main program; "import "fmt"" is introduced The fmt package is used to output "Hello Golang!" to the console; finally, a "main" function is declared through "func main() {...}".
Save the above code and enter
go run hello.go
on the command line. After running the program, you will see "Hello Golang!" output on the console, indicating that the program is successfully executed.
Summary:
This article introduces the process of installing Golang on Windows systems, including downloading the installation package, installation, environment variable settings and confirmation of installation and writing the first Golang program, etc. step. As an emerging programming language, Golang has good concurrency capabilities and operating efficiency, and is loved and favored by many developers. It is worthy of further exploration and study by developers who love programming.
