Golang的环境配置与helloworld运行

1. 环境配置

进入此https://studygolang.com/dl下载对应平台的对应版本

一路next就可以安装好并自动配置好环境变量

通过go envgo version命令语句查看是否安装好即可

前者返回如下即成功

后者返回对应版本go version go1.15.3 windows/amd64

2. 第一个golang程序 hello world

// Hello.go
package main

import (
    "fmt"
)

func main() {
    fmt.Println("Hello World! Welcome to Go Lang!") 
}

这里用的是vscode编译,可以用别的IDE比如LiteIDE和Goland
