title: running webpack upgrade to babel7 webpack3
body: <p>please help me understand why bable/runtime/helpers cannot resolve interopRequireDefault. I have just upgraded babel, tried to explicitly move my dependencies to babel 7.0.0. As far as I understand if the browser is not detected as supporting latest babel uses from the supplied "plugins" in my babelrc file.</p>
  
  <p>err is: Module build failed: TypeError: Cannot read property 'bindings' of null</p>
  
  <p>my babel-loader is definitely calling on files and initiating a compilation. Do I need to specify some other config or traverse process?</p>
