javascript - Karma - 找不到模块 : Error: Cannot resolve module 'scss'

Question

我有一个模块，我想为其编写测试。我使用 webpack 来转译它，因为我是用 ES6 编写的。

文件(app.js)如下所示:

import template from './app.html'; // pulls in the template for this component
import './app.scss'; // pulls in the styles for this component

但是当我运行测试时，我收到一个错误，找不到 app.scss

ERROR in ./src/app.js
Module not found: Error: Cannot resolve module 'scss' in /Users/.../src
 @ ./src/app.js 11:0-21

(browser) ERROR
  Uncaught Error: Cannot find module "./app.scss"
  at /Users/.../spec.bundle.js:34081 <- webpack:///src/app.js:4:0

Finished in 0.241 secs / 0 s

测试是这样开始的:

import angular from 'angular';
import header from './app.js'; // error occurs here cause .scss file is not recognized

describe('my module', () => {
  let $rootScope, makeController;
  // testing stuff
});

我的 karma.conf.js 文件包含以下内容:

webpack: {
  devtool: 'inline-source-map',
  module: {
    loaders: [
      { test: /\.js/, exclude: [/app\/lib/, /node_modules/], loader: 'babel' },
      { test: /\.html/, loader: 'raw' },
      { test: /\.scss/, loader: 'style!css!scss' },
      { test: /\.css$/, loader: 'style!css' }
    ]
  }
}

如何让 karma/webpack 正确读取 scss 文件并运行我的测试？

问题是一个拼写错误:

scss 应该是 sass

webpack: {
  module: {
    loaders: [
      ...,
      { test: /\.scss/, loader: 'style!css!sass' },
      ...
    ]
  }
}
