“WebDriver”对象没有属性“find_element_by_link_text” - Selenium 脚本突然停止工作

Question

这是我遇到的一个奇怪的问题，我在互联网上找不到任何解决方案。我在 google colab 中使用 selenium 来抓取网站，我的代码运行得很好。第二天我醒来，再次运行代码，没有更改任何一行，并且不知道我的代码如何/为什么开始给出此错误，AttributeError：“WebDriver”对象没有属性“find_element_by_link_text”。find_element_by_class_name 和 id 等也是如此。然后我重新检查了以前的工作脚本只是为了确认，这也给了我同样的错误。我对突然发生的事情感到困惑，脚本开始给我这些错误。

我该如何解决这个问题？我在这里做错了什么？

!pip install selenium
!apt-get update 
!apt install chromium-chromedriver

from selenium import webdriver
chrome_options = webdriver.ChromeOptions()
chrome_options.add_argument('--headless')
chrome_options.add_argument('--no-sandbox')
chrome_options.add_argument('--disable-dev-shm-usage')
driver = webdriver.Chrome('chromedriver',options=chrome_options)

driver.get("https://petrowiki.spe.org/PetroWiki")
driver.title #this line is returning the correct title value, code is able to access the url

peh = driver.find_element_by_link_text('Pet. Eng. Handbook')
peh.click()

为了提高可靠性，您应该考虑WebDriverWait与 结合使用element_to_be_clickable。
