golang quick build

With the continuous development of the Internet, the types of programming languages ​​are also constantly increasing and updating. Among them, golang, as an emerging programming language, has attracted more and more attention from developers because of its fast, safe, simple and easy-to-use characteristics.

In this article, I will share how to quickly build a golang development environment.

Step one: Install golang

The golang official website provides downloads of golang versions for various platforms. You can choose the corresponding version according to your computer system.

After the download is completed, just follow the download prompts to install it. After the installation is completed, open the command line window and enter the "go version" command. If the version number can be correctly output, the installation is successful.

Step 2: Install golang IDE

Although golang itself does not require the use of any specific IDE, it will be more convenient and faster to use the IDE. The following introduces several commonly used golang IDEs.

1. Visual Studio Code

Visual Studio Code is a free, lightweight, open source cross-platform IDE developed by Microsoft that supports golang development. After installing VS Code, search for golang extensions (such as Go, Go for Visual Studio Code, etc.) in the extension market, and then install it according to the prompts.

2. GoLand

GoLand is a professional golang IDE developed by JetBrains with very powerful functions. However, GoLand requires payment to use, but the IDEA Ultimate version also supports golang programming.

3. LiteIDE

LiteIDE is a free golang development environment that can be used on Windows, Linux and Mac OS X platforms. LiteIDE provides a simple UI and rich functions, such as code completion, jump to definition, refactoring, debugging, etc.

Step 3: Set golang environment variables

Setting golang environment variables is a key step to ensure the normal operation of golang.

Windows users need to perform the following steps:

1. Open the "Computer" or "My Computer" panel, right-click "Properties".
2. Click "Advanced System Settings" on the left, and click "Environment Variables" in the pop-up "System Properties".
3. In the pop-up "Environment Variables" window, find the "Path" variable under "System Variables" and click "Edit".
4. In the pop-up "Edit Environment Variables" window, add the golang bin directory path, for example: C:Program FilesGo in.
5. Click "OK" to save the settings, close all windows and restart the computer. The environment variable setting is completed.

Linux and Mac users need to perform the following steps:

1. Enter the terminal and enter the following command:

export GOROOT=/usr/local /go

export GOPATH=$HOME/go

export GOBIN=$GOPATH/bin

export PATH=$PATH:$GOROOT/bin:$GOBIN

2. Add the above commands to ~/.bashrc or ~/.bash_profile.
3. Update settings, enter the following command:

source ~/.bashrc

or

source ~/.bash_profile

After the setting is completed, open the command line window and enter "go". Some command instructions for golang should be output.

Step 4: Create golang project

In golang, each project needs to have a special directory structure. Create a new project directory under GOPATH using the project name as the directory name, for example:

mkdir $GOPATH/src/projectName

Create a file named main.go in the projectName directory, this It is the default compilation file of the golang compiler. Write the following code in main.go:

package main

import "fmt"

func main() {

fmt.Println("Hello, golang!")

}

This is the simplest golang program. Execute the command:

go run main.go

will output "Hello, golang!" to the command line window.

At this point, the steps to quickly build a golang development environment have ended. In the subsequent learning and development, you can use various excellent features of golang to quickly develop high-quality and efficient programs.
