Install yotta modules from github with git credentials

I'd like to do following but it fails:

$ yotta install git@github.com:ARMmbed/module-x.git

Fatal Exception, yotta=0.17.2

Please make sure you have the correct access rights

However, if I add the same address manually to module.json it works with yotta update.

"dependencies": {
    "module-x":"git@github.com:ARMmbed/module-x.git#master"
  },
