我已经对此问题进行了广泛的研究（我知道这是一个普遍的问题），但是找不到解决我特定问题的方法。
我有一个Angular 5项目，运行ng test或npm test会产生以下错误：
06 09 2018 10:19:32.062:INFO [PhantomJS 2.1.1 (Mac OS X 0.0.0)]: Connected on socket bASgocks3foEAV_OAAAA with id 63164390
PhantomJS 2.1.1 (Mac OS X 0.0.0) ERROR
ReferenceError: Can't find variable: require

这是我的karma.conf.js文件：
module.exports = function (config) {
config.set({

'src/testing/**/*.js'
],

这是我的gulpfile.js：

我知道可能有上百万个原因导致此错误，但是有关我的配置的任何事情都会发出警报吗？
