pre install golang

Golang

#apt 
#可以指定版本的
sudo apt install  golang

sudo apt  install golang-go gccgo-go
sudo apt  install golang-go 

FQ

tail  /etc/profile
#export http_proxy=http://192.168.10.173:8888
#export https_proxy=http://192.168.10.173:8888


source /etc/profile

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

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 get -u github.com/gin-gonic/gin #注意 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

cd   mygo/
mkdir  ginweb
cd ginweb/
go mod init ginweb
 go run example.go 

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

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]

trouble

working directory is not part of a module

关闭go代理就行了 

ct$ go run main.go 
main.go:6:2: cannot find module providing package github.com/gin-gonic/gin: working directory is not part of a module
evan@myxps:~/go/src/github.com/myusername/project$ go env -w GO111MODULE=off
