Error in compiling golang after migrating to centos

Question

I was migrating my Golang programs from windows to Centos 7

It worked perfectly in Windows
but when I tried to compile on centos I get errors like

main.go:20:3: cannot find package "github.com/BurntSushi/toml" in any of:
        /usr/local/go/src/github.com/BurntSushi/toml (from $GOROOT)
        /root/work/src/github.com/BurntSushi/toml (from $GOPATH)
main.go:15:3: cannot find package "github.com/dgrijalva/jwt-go" in any of:
        /usr/local/go/src/github.com/dgrijalva/jwt-go (from $GOROOT)
        /root/work/src/github.com/dgrijalva/jwt-go (from $GOPATH)
main.go:16:3: cannot find package "github.com/gwlkm_service/config" in any of:
        /usr/local/go/src/github.com/gwlkm_service/config (from $GOROOT)
        /root/work/src/github.com/gwlkm_service/config (from $GOPATH)

kinda new to centos so idk what to do

Are you using any Go dependency management like `dep` or `go module`? — Wanda Ichsanul Isra, Dec 30 '19 at 07:03

looks like you have configured your GOPATH, without Go Module, you can use go get [package path] to download imported packages.

go get github.com/BurntSushi/toml
go get github.com/dgrijalva/jwt-go
go get github.com/gwlkm_service/config

if i would ask, where does the system save the file after go get? – arsaphone Dec 30 '19 at 07:15
in the `$GOPATH/src` – beiping96 Dec 30 '19 at 07:16
oh yeah thanks! any other way to run that main.go as background process as windows? – arsaphone Dec 30 '19 at 07:47

Precisely

your go installation on server seems in /usr/local/go and your project is in /root/work so all your dependencies should be either in /root/work/src or /usr/local/go/src

now coming to action check your GOPATH with running echo $GOPATH assuming it is automatically set to /usr/local/go/src If not then follow - How do I SET the GOPATH environment variable on Ubuntu? What file must I edit?

If everything is ok then in your folder run go mod init

this will create mod file which will help you in further installations look into - https://blog.golang.org/using-go-modules

then run go get commands as above @beiping96 said

go get github.com/BurntSushi/toml go get github.com/dgrijalva/jwt-go go get github.com/gwlkm_service/config

NOTE - after completing above process you will generate go modules file(same as package.json) and in future you won't need to care about dependencies

Okay sir thanks. any way to run the main.go as background process? — arsaphone, Dec 30 '19 at 07:59
use `pm2` *or* use nohup *or* add & in the end of command like `go run main.go &` — anshuVersatile, Dec 30 '19 at 08:27
