单元测试在Chrome中通过，在PhantomJS中失败。我正在使用以下库
karma-jasmine
karma-chrome-launcher
karma-jasmine-html-reporter
karma-spec-reporter
karma-phantomjs-launcher
karma-coverage-istanbul-reporter
@angular-devkit/build-angular/plugins/karma
当我运行单元测试并将浏览器用作Chrome时，所有单元测试都将通过。当我将其用作PhantomJS时，会出现错误。
错误：
PhantomJS 2.1.1 (Windows 7.0.0) ERROR

我尝试安装新版本的zoneJS并进行了检查，但无法正常工作。我修改了某些版本的插件，但没有运气。

请帮助我了解这是库问题还是测试用例问题
