There are conflicts when execute npm install

I'm following the quickstart in https://frint.js.org/docs. I installed frint, I initialized an example app, but, when I execute npm install, throw those errors:

npm ERR! While resolving: frint-kitchensink@0.0.1
npm ERR! Found: webpack@3.12.0
npm ERR! node_modules/webpack
npm ERR!   dev webpack@"^3.0.0" from the root project
