我正在关注一个angular-webpack教程，当学习使用karma进行测试时，webpack被用作karma配置文件中的预处理器，并且其条目被设置为karma的监视文件：所以这就是整个{{ 1}}：
karma.config.js这是前一个文件中所需的var path = require('path');
var webpackConfig = require('./webpack.config');
var entry = path.resolve(webpackConfig.context, webpackConfig.entry);
var preprocessors = {};
preprocessors[entry] = ['webpack'];
// Karma configuration
// Generated on Wed Sep 14 2016 08:47:45 GMT+0100 (Afr. centrale Ouest)
module.exports = function(config) {
config.set({
// base path that will be used to resolve all patterns (eg. files, exclude)
basePath: '',
// frameworks to use
// available frameworks: https://npmjs.org/browse/keyword/karma-adapter

webpack.config.js当我试图开始业力测试时，我得到以下错误：
