Go language | 01 wsl+vscode environment construction pit avoidance Guide

Preface

Because of work , Need to use Go Language development , As an embedded Developer , The soldiers came to cover the water

Go The language is designed as an application for carrying Web The server , System programming language for storage cluster or similar giant central server .

For the field of high-performance distributed systems ,Go Language is undoubtedly more efficient than most other languages . It provides massive parallel support , This is no better for the development of the game server .

Go Download and install the installation package

https://studygolang.com/dl

The development environment is WSL, So choose Linux Version download

Find a location to extract the file after downloading

Execute the decompression instruction

tar zxvf go1.18.3.linux-amd64.tar.gz

Take the decompressed go Copy folder to home Under the table of contents , You can also define , But remember your own directory

Start configuring the environment

It is recommended to create in the same directory go Language workspace folder , I have a new one here gopath Folder , Path is /home/gopath.

sudo nano /etc/profile

Then add... At the end of the open file ：

export GOROOT=/home/go
export GOPATH=/home/gopath
export PATH=$PATH:$GOROOT/bin:$GOPATH/bin
export GOPROXY="https://goproxy.io"
source .bash_profile

Then refresh the document

source /etc/profile

The environment here is global

Last run

go version

Fill in these two directories according to your own situation export GOROOT=/home/go;export GOPATH=/home/gopath

Check the installation

Here is a sample code

Save as .go File format

package main

import "fmt"

func main() {
    
    fmt.Printf("hello, world\n")
}

perform

go run test.go

You can see

Express Go Download and installation succeeded , But we must not stop here , We should make development humanized

Need to borrow VSCode

VSCode build

from Windows Open up our VSCode, Then remote to WSL

install Go plug-in unit

If we do the sample code directly F5 function , Prompt to install some packages

The direct click probability is that the installation fails

We need to operate alone , because dlv It mainly involves debug debugging

It is also an important tool for us to develop happiness index

dlv install

go install github.com/go-delve/delve/cmd/[email protected]

After confirming that GCC after , Return as prompted VSCode Re install dlv

Wait a moment

You can see the prompt success

here F5, Found that it still can't run

terms of settlement :

go env -w GO111MODULE=auto

OK！ The environment was successfully built
