Golang installation and configuration tips: start learning from the basics

Learn Golang installation and configuration skills from scratch

Golang is a programming language developed by Google. It is designed to be simple, efficient and easy to learn. For developers who want to get started with Golang, they must first learn how to install and configure the Golang development environment. This article will introduce in detail how to learn Golang from scratch, including Golang installation and configuration tips, and provide specific code examples to help readers better understand.

1. Installation of Golang

The installation of Golang is very simple. You only need to install it according to the installation package provided by the official website. The following are the steps to install Golang:

1. Open the Golang official website (https://golang.org/) and find the installation package download link suitable for your operating system. Currently, the official website provides installation packages for various operating systems such as Windows, Mac OS and Linux.
2. Click the download button and wait for the installation package to be downloaded. After the download is complete, double-click the installation package to execute the installation program.
3. Select the installation path in the installer. By default, Golang will be installed in the C:Go (Windows) or /usr/local/go (Linux or Mac OS) path.
4. After completing the installation, you can enter "go version" in the command line to check whether Golang is successfully installed. If the installed Golang version number is displayed, the installation is successful.

2. Golang configuration

After installing Golang, you need to perform some configuration before you can start using Golang for development. The following are the configuration steps of Golang:

1. Configure GOPATH: GOPATH is the working directory of Golang, which is used to store the code, packages and dependencies of the Golang project. You can configure GOPATH in your environment variables or set it manually. In Linux or Mac OS, you can add the following code in the .bashrc or .zshrc file:

export GOPATH=$HOME/go
export PATH=$PATH:$GOPATH/bin

In Windows, you can add GOPATH in system variables and add GOPATH in to the environment variable PATH.

2. Configure editor: Choose a code editor that suits your preferences to write Golang code. Currently, the more popular editors include Visual Studio Code, GoLand, Sublime Text, etc. Choose a suitable editor according to your actual needs.
3. Download third-party package management tools: There are many kinds of package management tools in Golang, the more commonly used ones are go modules, dep, etc. You can choose a suitable package management tool according to your needs. You can install go modules through the following command:

go get -u golang.org/x/tools/cmd/goimports

4. Configure proxy: If you use Golang in China, you may need to configure Agent to access some foreign code libraries. You can use the following command to configure the agent:

go env -w GOPROXY=https://goproxy.cn,direct

After the configuration is completed, you can start using Golang for development. Next let’s look at a simple Golang code example:

package main

import "fmt"

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

Save the above code as a hello.go file, and then run the following command on the command line to compile and run the code:

go run hello.go

If everything goes well, you will see the output on the command line: "Hello, Golang!".
