尝试使用量角器在Angular2应用上运行集成测试：
protractor.conf.js
exports.config = {
baseUrl: 'http://localhost:3000',
seleniumAddress: 'http://localhost:4444/wd/hub',
specs: [
'src/app/e2e/contact.e2e.js'
],
framework: 'jasmine',
useAllAngular2AppRoots: true
};
我的测试文件： contact.e2e.js
describe('App', function(){
it('should render the contact section', function() {
browser.get('/');
expect(true).toBe(true);
});
});
我得到的错误：
Message:

奇怪的是，它只发生在我的Mac上，当我通过我的jenkins服务器上的docker运行测试时，它运行正常。 将非常感谢帮助。 提前谢谢。
更新
我的量角器不是全局的，我运行的量角器版本是：版本4.0.14
答案 0 :(得分：1)
有几个要解决的问题：
devDependencies ：Protractor 4.0.11使用selenium-webdriver 2.53.1。你也有不同的selenium-webdriver 2.47.0作为项目中的devDependency。
堆栈跟踪：错误selenium-webdriver/lib/goog/../webdriver/promise.js是可疑的，因为Protractor在^ 4.0.11中使用的selenium-webdriver节点模块中不存在/lib/goog/。我怀疑你使用的是旧版本的Protractor。
lib/goog/ lib/goog/ lib/goog/ 我会检查你是如何运行量角器的。我认为您是从全局环境运行它，应该尝试protractor --version进行验证。
也很有帮助的是将脚本添加到package.json
"scripts": {
"e2e": "protractor some/path/to/conf.js"
}
然后使用npm run e2e执行此操作。这将确保您使用项目中项目node_modules的量角器。
<强>更新
上面的答案，我改变了2.47.0确实有路径/lib/goog/。我真的很晚才回答，可能写错了。这可能是因为我做了npm i -S selenium-webdriver@^2.47.0。不知怎的，你已经声明你想要^ 2.47.0但是如果你收缩包装2.47.0则会阻止胡萝卜下载最后一个次要版本。
对答案的改进。下面的堆栈跟踪引用了两个不同版本的selenium-webdriver。 selenium-webdriver是Protractor的一部分，是另一个版本。不在量角器中的selenium-webdriver指的是路径lib/goog/。

at promise.Promise.then (/Users/yarivkatz/Development/workspace/bugeez/bugeez-lp-final/node_modules/selenium-webdriver/lib/goog/../webdriver/promise.js:592:15)

如上所述，在更新中，我相信你的selenium-webdriver版本中有一些东西被锁定了。另外，因为你有两个版本的selenium-webdriver，你正在调用node_modules/protractor/node_modules/selenium-webdriver并以某种方式调用node_modules/selenium-webdriver/lib/goog/。
请删除devDependency，将其从shrinkwrap中删除，然后重新安装依赖项。
