Question

我在下面的代码中尝试启动chrome，访问网站并登录。这是基于我在以下回购中找到的代码的基础：

https://github.com/AlbanyCompSci/aeries-api 基本上是为了帮助我登录这个叫做aeries的年级门户网站，并使我的孩子们升入高中。我收到与“ phantomjs”有关的错误。同样，在抛出关于chrome的错误之前，它必须是无头的。我在较早的文章中获得了帮助： phantomjs issue on mac with jupyter notebook 建议使用chromedriver而不是phantomjs。现在，我不再像以前的文章中那样从仓库中加载模块，而是使用仓库中的代码片段，并尝试逐步了解它们的工作方式。我正在使用python 3.6在jupyter笔记本中的Mac上运行它。任何提示，不胜感激。当我运行下面的代码时，出现与代码的“ password_elem.send_keys（password）”部分相关的“ ElementNotVisibleException”错误。有谁知道可能导致该问题的原因，您能建议如何解决吗？我是硒的新手，因此非常感谢您提出任何建议。

键入电子邮件后，您缺少下一个按钮。

email_elem = driver.find_element_by_id(EMAIL_ID)
email_elem.send_keys(email)

driver.find_element_by_id('next').click() // you are missing this

password_elem = driver.find_element_by_id(PASSWORD_ID)
password_elem.send_keys(password)
login_elem = driver.find_element_by_id(LOGIN_ID)
login_elem.click()

password_elem中的硒ElementNotVisibleException
