Does golang need to be installed?

Golang is an open source programming language, also known as Go language. It was released by Google in 2009 to provide a fast, reliable and easy-to-build software development tool. As a modern language, it has powerful concurrent programming capabilities and efficient memory management. Therefore, it is welcomed by many software engineers. In this article, we will introduce the installation and use of Golang.

First of all, it should be clear that Golang needs to be installed. Before installing Golang, we need to determine what type of system we have. The operating systems supported by Golang include Linux, Windows, macOS and FreeBSD. Then, we need to visit the Golang official website (https://golang.org/dl/) to download the Golang installation package. Select the corresponding version to download based on our operating system type and bit number. For example, if we are using a Linux system, then we can choose to download the Linux .tar.gz file.

After the download is completed, we need to perform the following operations to install:

1. Unzip the installation package. We can use the tar command to decompress the .tar.gz file. The command is as follows:

tar -C /usr/local -xzf go$VERSION.$OS-$ARCH.tar.gz

where , VERSION represents the version of Golang, OS represents the operating system type, and ARCH represents the number of bits of the operating system (for example, amd64).

2. Add Golang’s bin directory to the system PATH. We need to add the following commands to the .bashrc or .bash_profile file:

export PATH=$PATH:/usr/local/go/bin

After executing the above two steps, we will install successfully Golang.

Next, we can try the use of Golang. We can use a simple Hello World program to verify that our installation is correct. We can write the following program in any text editor:

package main

import "fmt"

func main() {

fmt.Println("Hello, World!")

}

Save the program as hello.go file. We can then switch to the directory where the file is located on the command line and enter the following commands to compile and run:

go run hello.go

If everything is OK, we will see the following Output:

Hello, World!

At this point, we have successfully written our first program in Golang.

In addition to using the command line to compile and run, we can also use the integrated development environment (IDE) provided by Golang for development. For example, Gogland, Visual Studio Code, etc. all support Golang development. Using IDE development can facilitate us for debugging and code writing.

In short, Golang is a very powerful programming language, especially in the field of network programming and big data processing. Although installation and setup require some time and effort, by carefully reading the official documentation, you will get started easily. If you are an experienced developer, consider giving Golang a chance and you will find that it is a language worth learning and putting into use.
