Odep go run ./mattermost.go -create_team -team_name fails

I followed the steps listed on http://docs.mattermost.com/developer/developer-setup.html to install mattermost on Mac,

and make test passed,

however, the following command fails with the error listed below,

godep go run ./mattermost.go -create_team -team_name="rocks" -email="abc@gmail.com"
godep: No Godeps found (or in any parent directory)

And http://localhost:8065 shows the login page

Any idea why the above command failed?

Thanks,
