PhantomJS/Chrome 在 Angular 6 项目中使用 "Zone\nat"/"Script error" 在 Karma 测试中失败

Question

大家好 Whosebug，

我卡住了！我的 ng test 失败了，尽管 ng serve 可以毫无问题地构建和编译这个 Angular 6 项目。我收到的错误如下：

此外，紧接着 Chrome 失败，就像这样：

我几乎不了解发生了什么，但是这个问题阻止了成功部署，因为 build-street 失败了。

作为一个菜鸟，我正在疯狂地尝试应用与我的问题非常相似的解决方案，但无济于事。这就是为什么我向你们寻求帮助的原因！我试过 ;将 polyfills.ts 中的 import 'zone.js/dist/zone' 放在文件的顶部；更新 PhantomJS 等等。

我的karma.conf.js如下：

module.exports = function (config) {
  config.set({
    basePath: '',
    frameworks: ['jasmine', '@angular-devkit/build-angular'],
    plugins: [
      require('karma-jasmine'),
      require('karma-chrome-launcher'),
      require('karma-phantomjs-launcher'),
      require('karma-jasmine-html-reporter'),
      require('karma-coverage-istanbul-reporter'),
      require('@angular-devkit/build-angular/plugins/karma')
    ],
    /*...*/
    browsers: ['Chrome', 'PhantomJS'],
    singleRun: true
  });
};

不知道是否有帮助，但我的 package.json 看起来像这样：

在经历了所有的痛苦之后，我发现我所要做的就是将参数传递给 ng test，就像我的 ng test isms-frontend 一样。从 jorgjanke 找到答案，最后从 https://github.com/angular/angular-cli/issues/12581
