install Gin package

 export PATH=/usr/local/go/bin/:$PATH
 export GOPATH=/root/go #if U user is root 

If you're in China

如果您使用的 Go 版本是 1.13 及以上

#nov 29 2021
 export GO111MODULE=on
 export GOPROXY=https://goproxy.cn


or

echo "export GO111MODULE=on" >> ~/.profile
echo "export GOPROXY=https://goproxy.cn" >> ~/.profile
source ~/.profile



go env -w GO111MODULE=on #注意这个打开后面可能会问题导致
go env -w GOPROXY=https://goproxy.io,direct

#or
go env -w GOPROXY=https://mirrors.aliyun.com/goproxy/,direct

# 设置不走 proxy 的私有仓库，多个用逗号相隔（可选）
go env -w GOPRIVATE=*.corp.example.com

# 设置不走 proxy 的私有组织（可选）
go env -w GOPRIVATE=example.com/org_name

Go 版本是 1.12 及以下

# 启用 Go Modules 功能
export GO111MODULE=on
# 配置 GOPROXY 环境变量
export GOPROXY=https://goproxy.io

或者，根据文档可以把上面的命令写到.profile或.bash_profile文件中长期生效

初始化 gin

go mod

go env -w GO111MODULE=on #注意这个打开后面可能会问题导致
go env -w GOPROXY=https://goproxy.io,direct

cd   mygo/
mkdir  ginweb
cd ginweb/
go mod init ginweb(名字自定义)
go get -u github.com/gin-gonic/gin #注意 ，用go mod 来管理  june   08 2020  goverdor 已过期 请用 go mod  安装一般用下面的goverdor 版本管理 tool 去安装 这一块可以直接跳过
 go run example.go 

ps 
evan@myxps:~/mygo/ginweb$ echo $GOROOT
/home/evan/go
evan@myxps:~/mygo/ginweb$ echo $GOPATH
/home/evan/go

#别人的例子
编写 HelloWorld 文件，测试运行环境。

package main
import "fmt"
func main(){
    fmt.Println("hello,world!")
}

go run hello.go
go build hello.go 

创建 go.mod 文件

go mod init hello

用 Gin 实现一个简单的 http 服务

import (
    "gopkg.in/gin-gonic/gin.v1"
    "net/http"
)

func main(){
    
    router := gin.Default()

    router.GET("/", func(c *gin.Context) {
        c.String(http.StatusOK, "Hello World")
    })
    router.Run(":8000")
}

直接编译执行 

go run hello

可以看到引用的包都被自动下载了

放弃了 Use a vendor tool like Govendor

 go get -u -v github.com/kardianos/govendor
 go get github.com/kardianos/govendor #在墙外非常快

sudo apt  install govendor # apt 

mkdir -p $GOPATH/src/github.com/myusername/project && cd "$_"

Vendor init your project and add gin

govendor init
govendor fetch github.com/gin-gonic/[email protected]

#有时要绝对路径  @后面也可以不加  有时一定要加
/root/go/bin/govendor fetch github.com/gin-gonic/[email protected]
