DEPRECATION: An addon is trying to access project.nodeModulesPath. This is not a reliable way to discover npm modules. Instead, consider doing: require("resolve").sync(something, { basedir: project.root }). Accessed from:   new NPMDependencyVersionChecker (/Users/julien/Projects/ember-addons/ember-leaflet/node_modules/ember-cli-version-checker/src/npm-dependency-version-checker.js:11:33)

Expected result

No deprecation message
