I has stucked with this problem too.

And it works after I open page in browser: http://localhost:3000

$ go version
go version go1.11.1 linux/amd64
$ gin -v
gin version 0.0.0

Hmm.. I have found reason. Now I run command with -i flag:

$ gin -i run main.go

And it works well:

$ gin -i run main.go

About this option:

--immediate, -i               run the server immediately after it's built
