我的e2e文件夹已被删除，现在我正尝试从新项目中添加新文件夹，但是我遇到了一些问题：
ng e2e 有效并且出现导航，但是默认测试无效：
当我执行 ng e2e 时：
PS D:\Front> ng e2e

并且在我的 app.po.ts 中，他不知道量角器的导入方式：
import { browser, by, element } from 'protractor';
export class AppPage {
navigateTo() {
return browser.get('/');
}
getParagraphText() {
return element(by.css('app-root h1')).getText();
}
}
这是我的 app.e2e-spec.ts （他不知道描述，每个人，它，并且期望）：
import { AppPage } from './app.po';
describe('workspace-project App', () => {
let page: AppPage;
beforeEach(() => {
page = new AppPage();
});
it('should display welcome message', () => {
page.navigateTo();
expect(page.getParagraphText()).toEqual('Welcome to MyProject!');
});
});
之后，我在全局量角器中停滞，并执行了 webdriver-manager更新和 webdriver-manager start ，第一个告诉我：
