運行量角器打字稿時npm測試時拋出錯誤

Question

在使用npm測試的Visual Studio代碼中運行量角器測試時，出現如下錯誤，好像是node_modules/@types/jasmine/index.d.ts問題，如何擺脫這個錯誤？

以下是我已經習慣了在Visual Studio代碼打字稿和茉莉框架運行量角器

的package.json

    } 
} 

spec.ts文件

import {browser, element, by, By, $, $$, ExpectedConditions} from 'protractor'; 

describe('protractor with typescript typings',() => { 
    beforeEach(() => { 
    browser.get('http://www.angularjs.org'); 
    }); 

    it('should greet the named user',() => { 
    element(by.model('yourName')).sendKeys('Julie'); 
    let greeting = element(by.binding('yourName')); 
    expect(greeting.getText()).toEqual('Hello Julie!'); 
    }); 

    it('should list todos', function() { 
    let todoList = element.all(by.repeater('todo in todoList.todos')); 
    expect(todoList.count()).toEqual(2); 
    expect(todoList.get(1).getText()).toEqual('build an angular app'); 
    }); 
}); 

tsconfig.json

}

我有同樣的問題，我固定它執行以下操作：

1）我換成"@types/jasmine": "2.5.41"爲"@types/jasmine": "^2.5.51"和 "typescript": "~2.0.0"爲"typescript": "2.1"

2）I執行npm install && npm test。我有一個新的錯誤，所以我接下來的兩個步驟。

3）I執行node_modules /的.bin/webdriver的管理器更新

4）在conf.ts註釋的線路輸出 seleniumAddress: 'http://localhost:4444/wd/hub',

5）本人執行npm test和它的工作。
