尝试所有元素属性后，使用 RubyMine 使用 Selenium 时出现 NoSuchElementError

Question

我想为这个网站编写一些测试：https://roomy-fire-houseboat.glitch.me/但无法找到任何元素。我可以启动网站，然后添加 5 秒的睡眠时间。

这是 RubyMine 中的错误：

Selenium::WebDriver::Error::NoSuchElementError: no such element: Unable to locate element: {"method":"css selector","selector":"#number"}
  (Session info: chrome=123.0.6312.59); For documentation on this error, please visit: https://www.selenium.dev/documentation/webdriver/troubleshooting/errors#no-such-element-exception

这是当前行，我用来在网站上查找文本框。

driver.find_element(:id, 'number')

我也尝试过：css和：xpath。

当我检查元素时，我得到以下信息：

id =“号码” 类型=“文本”

选择器=#number

xpath = //*[@id="number"]

不确定你的程序是什么，我编写了以下程序，它对我来说效果很好。

require 'selenium-webdriver'

driver = Selenium::WebDriver.for :chrome

driver.navigate.to 'https://roomy-fire-houseboat.glitch.me/'

driver.find_element(id: 'number').send_keys '2'

driver.find_element(id: 'start').click

sleep 10

您可以尝试一下吗，如果您遇到任何问题请告诉我。
