Получение ошибки, связанной с Webpack при выполнении модульного теста для Vue

Я запустил веб-приложение, изменив https://github.com/vuejs/vue-hackernews-2.0. Я начал писать модульные тесты также для этого.

Я получаю следующие webpack ошибка при настройке модульного теста для моего веб-приложения Vue:

23 11 2016 17:13:18.968:ERROR [preprocess]: Can not load "webpack"!
  WebpackOptionsValidationError: Invalid configuration object. Webpack has been initialised using a configuration object that does not match the API schema.
 - configuration has an unknown property 'vue'. These properties are valid:
   object { amd?, bail?, cache?, context?, dependencies?, devServer?, devtool?, entry, externals?, loader?, module?, name?, node?, output?, plugins?, profile?, recordsInputPath?, recordsOutputPath?, recordsPath?, resolve?, resolveLoader?, stats?, target?, watch?, watchOptions? }
   For typos: please correct them.
   For loader options: webpack 2 no longer allows custom properties in configuration.
     Loaders should be updated to allow passing options via loader options in module.rules.
     Until loaders are updated one can use the LoaderOptionsPlugin to pass these options to the loader:
     plugins: {
       new webpack.LoaderOptionsPlugin({
         // test: /\.xxx$/, // may apply this only for some modules
         options: {
           vue: ...
         }
       })
     }
 - configuration.module has an unknown property 'preLoaders'. These properties are valid:
   object { exprContextCritical?, exprContextRecursive?, exprContextRegExp?, exprContextRequest?, loaders?, noParse?, rules?, unknownContextCritical?, unknownContextRecursive?, unknownContextRegExp?, unknownContextRequest?, wrappedContextCritical?, wrappedContextRecursive?, wrappedContextRegExp? }
   Options affecting the normal modules (`NormalModuleFactory`).

Вы используете конфигурацию для webpack 1.x, но ваша версия webpack - 2.x.

В веб-пакете 1.x вы можете иметь пользовательские параметры в конфигурации. Vue использовал это, используя свойство vue в конфигурации. Теперь в webpack 2.x вы не можете этого сделать.

Hackernews теперь поддерживает webpack 2.x, поэтому, если вы загрузите свежую версию, она будет правильно скомпилирована.
