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

#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]
