Found following 2 similar issues with other projects: https://github.com/isaacs/node-semver/issues/67 https://github.com/sindresorhus/load-grunt-tasks/issues/24

It was not clear to me how to "upgrade" npm in TravisCI. Finally figure this out by doing following in .travis.yml:

before_script:
  - npm update -g npm
