javascript - 从 WebStorm 运行 Protractor 测试时，在导入语句中获取意外的标记 {

Question

我使用的是 Node 6.4.1 和 esversion 6。

我正在尝试从 WebStorm 运行 Protractor 测试，但在运行时出现以下错误。浏览器已成功调用，但随后停止。

Error:

});

});

it('should add one and two', function() {

  goButton.click();

  expect(latestResult.getText()).toEqual('3');
 });

 it('should add four and six', function() {
  firstNumber.sendKeys(4);
  secondNumber.sendKeys(6);

  goButton.click();
  expect(latestResult.getText()).toEqual('10');
  });

 it('should read the value from an input', function() {
   firstNumber.sendKeys(1);
   expect(firstNumber.getAttribute('value')).toEqual('1');
  });
});

我承认我不熟悉 webstorm，但我认为没有理由需要在规范文件中导入这些内容。 Protractor 应在自动启动时设置这些变量。我可能错过了一些东西，但是您可以尝试删除它们并查看您的项目是否可以运行。

import {WebDriver as browser}  from "selenium-webdriver";
import {By as by} from "selenium-webdriver";
import {beforeEach, describe, it} from "selenium-webdriver/testing";
import {element} from "protractor";
