Cannot build open-source project - macos

Question

I'd like to contribute to an OSS project built with go, but I'm having hard time compiling it. It looks as if I'm missing something obvious.
I think the problem is related to how go is installed on my computer, and not to the project itself, thus I'm posting it here on StackOverflow, instead of project's "Issues" section.
Below is what I'm doing.
I've installed go using homebrew:
$ brew install go

==> Caveats
A valid GOPATH is required to use the `go get` command.
If $GOPATH is not specified, $HOME/go will be used by default:
https://golang.org/doc/code.html#GOPATH
You may wish to add the GOROOT-based install location to your PATH:
export PATH=$PATH:/usr/local/opt/go/libexec/bin
==> Summary
🍺 /usr/local/Cellar/go/1.8.3: 7,035 files, 282.0MB
$
Then I cloned the repo:
$ hub clone lucapette/fakedata
I ran make setup (per instruction), which at first did not complete successfully:
$ make setup
go get -u github.com/alecthomas/gometalinter
gometalinter --install
make: gometalinter: No such file or directory
make: *** [setup] Error 1
$
I figured that is because gometalinter is nowhere in my $PATH, so have added it (I'm using fish-shell):
$ set fish_user_paths /Users/gmile/go/bin
running make setup seem to have succeeded now. This is the output:
$ make setup
go get -u github.com/alecthomas/gometalinter
gometalinter --install

Running make build fails:
$ make build
go build
main.go:11:2: cannot find package"github.com/lucapette/fakedata/pkg/fakedata" in any of:
/usr/local/Cellar/go/1.8.3/libexec/src/github.com/lucapette/fakedata/pkg/fakedata (from $GOROOT)
/Users/gmile/go/src/github.com/lucapette/fakedata/pkg/fakedata (from $GOPATH)
main.go:12:2: cannot find package "github.com/spf13/pflag" in any of:
/usr/local/Cellar/go/1.8.3/libexec/src/github.com/spf13/pflag (from $GOROOT)
/Users/gmile/go/src/github.com/spf13/pflag (from $GOPATH)
make: *** [build] Error 1
$
So either Contributing guideline is incomplete, or I'm missing something obvious about installing and managing go packages.

Answer 1

Your path when cloning the source must be on the golang PATH like :
/home/gujarat/golang/src/github.com/lucapette/fakedata
as you can see my Path to golang path is : /home/gujarat/golang/.
You can also print your golang path in your terminal by entering : $GOPATH.
And the git clone should be in the following the exact as above path : src/github.com/lucapette/.
cd $GOPATH/src/github.com/
mkdir lucaptte
cd lucapette
git clone https://github.com/lucapette/fakedata.git
When you are running the make command which trigger go build this command will look the $GOPATH and your $GOROOT folder.

Answer 2

Your go source should in your gopath - here it is Users/gmile/src. Use go get to fetch the pkg you want to work on instead and it should work.
