尝试使用打字稿运行量角器，但出现以下错误

我的设置就像

spec.ts

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

}

我在全球范围内安装了量角器，茉莉花，打字稿。仍然会出现上述错误，conf.ts也会在量角器文本上引发错误，如图所示请指导设置出错的地方。

Answer 1

由于您已在全局安装了上述模块，因此它们应该在没有npm安装的情况下工作。

尽管如此，您应该在package.json中将这些模块作为依赖项。这显然是一个路径问题，npm无法在npm install期间找到量角器模块。

您有2个选项 -

更正package.json中的本地量角器路径

"dependencies": {
"@types/jasmine": "2.5.41",
"@types/jasminewd2": "^2.0.0",
"jasmine": "^2.4.1",
"protractor": "C:/Users/skp/AppData/Roaming/npm/node_modules/protractor",
"typescript": "~2.0.0"
},

提及package.json中的量角器版本，就像你对其余模块所做的一样

"dependencies": {
"@types/jasmine": "2.5.41",
"@types/jasminewd2": "^2.0.0",
"jasmine": "^2.4.1",
"protractor": "^5.1.1",
"typescript": "~2.0.0"
},

现在如果你运行``npm install`，它应该成功安装依赖项。

Answer 2

提供依赖后，您必须运行npm install。

//conf.ts
// An example configuration file.
exports.config = {
  directConnect: true,

  // Capabilities to be passed to the webdriver instance.
  capabilities: {
    'browserName': 'chrome'
  },

  // Framework to use. Jasmine is recommended.
  framework: 'jasmine',

  // Spec patterns are relative to the current working directory when
  // protractor is called.
  //specs: ['../Tests/LoginTestCases.js'],



  // Options to be passed to Jasmine.
  jasmineNodeOpts: {
    defaultTimeoutInterval: 30000
  }
};


//Package.json
{
  "name": "newprotractor",
  "version": "1.0.0",
  "description": "",
  "main": "index.js",
  "scripts": {
    "test": "echo \"Error: no test specified\" && exit 1"
  },
  "author": "",
  "license": "ISC",
  "dependencies": {
    "@types/jasmine": "2.8.7",
    "@types/jasminewd2": "2.0.3",
       "@types/node": "12.12.2",
    "jasmine": "3.5.0",
       "protractor": "^5.4.2",
    "protractor-jasmine2-html-reporter": "^0.0.7",
    "ts-node": "8.5.4",
    "typescript": "3.4.3",
    }
}

使用命令npm install，量角器将为当前项目安装，然后错误将消失
