使用 angular-cli 运行 Protractor 时 SpecReporter 不是构造函数错误

当我尝试跑步时ng e2e或直接protractor命令我收到此错误：

[14:39:00] I/update - chromedriver: chromedriver_2.28 up to date

这是因为 Jasmine 发生了重大变化。将量角器配置文件更改为：

var SpecReporter = require('jasmine-spec-reporter').SpecReporter;

代替：

var SpecReporter = require('jasmine-spec-reporter');
