Question

除了this post之外，我遵循了步骤而不是

def start(self, scheduler, alias):
    """
    Called by the scheduler when the scheduler is being started or when the executor is being added to an already
    running scheduler.

    :param apscheduler.schedulers.base.BaseScheduler scheduler: the scheduler that is starting this executor
    :param str|unicode alias: alias of this executor as it was assigned to the scheduler
    """

    self._scheduler = scheduler
    self._lock = scheduler._create_lock()
    self._logger = logging.getLogger('apscheduler.executors.%s' % alias)

我申请了

npm install -g protractor

我成功完成了Step 0 - write a test

npm install -g protractor --no-optional

然而，当我尝试Step 1 - interacting with elements

时

expect(browser.getTitle()).toEqual('Super Calculator');

它给出错误：

element(by.model('first')).sendKeys(1);

我可以看到我可以通过测试来访问dom元素：

Using the selenium server at http://localhost:4444/wd/hub
[launcher] Running 1 instances of WebDriver
F

Failures:

  1) Protractor Demo App should add one and two
   Message:
     UnknownError: null
   Stacktrace:
     UnknownError: null
   //... continue stack trace

然后它说，

element(by.model('firstXXX')).sendKeys(1);

上面提到的错误消息可能是什么原因：

NoSuchElementError: No element found using locator: by.model("firstXXX")

也从Message: UnknownError: null控制台输出：

webdriver-manager start

您应该在使用seleniumAddress时解决问题，但也可以使用directConnect自动执行Chrome和Firefox，示例配置为here。
