webpack.optimize.OccurenceOrderPlugin is not a constructor Error

[outsideris]

When I run npm test, I encountered following error.

webpack-validator/test/passing-configs/angular2-webpack-starter.development.js:73
  plugins: [new webpack.optimize.OccurenceOrderPlugin(true), new webpack.optimize.CommonsChunkPlugin({ name: 'polyfills', filename: 'polyfills.bundle.js', minChunks: Infinity }),
            ^

npm ERR! Test failed.  See above for more details.

As I dig the reason, I guess it caused because OccurenceOrderPlugin has been renamed to OccurrenceOrderPlugin. See webpack/webpack#1964 .
All tests are passed when I change OccurenceOrderPlugin to OccurrenceOrderPlugin in the test.

However, I'm not sure it is a common problem or just for me.

In my pull request, the same error is occurred. If you confirmed, I could fix it.

If you're using Webpack 2, then please uninstall webpack-validator and close this issue. See the note in the README about webpack 2 not being supported (it has its own validation built-in 🎉)

As said above OccurenceOrderPlugin is renamed to OccurrenceOrderPlugin (spelling mistake)

However it was not mentioned that it is now enabled by default - so you can just remove the line

    new webpack.optimize.OccurenceOrderPlugin(),

@simeyla It does not work. Then output:
WebpackOptionsValidationError: Invalid configuration object. Webpack has been initialised using a configuration object that does not match the API schema.
