我通过修改vue-hackernews-2.0启动了一个 webapp 。我也开始为它编写单元测试。
webpack为我的 Vue Web 应用程序设置单元测试时出现以下错误：
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`).
