Answer 1

Selenium 刚刚在版本

4.3.0

中删除了该方法。查看更改：https://github.com/SeleniumHQ/selenium/blob/a4995e2c096239b42c373f26498a6c9bb4f2b3e7/py/CHANGES

Selenium 4.3.0
* Deprecated find_element_by_* and find_elements_by_* are now removed (#10712)
* Deprecated Opera support has been removed (#10630)
* Fully upgraded from python 2x to 3.7 syntax and features (#10647)
* Added a devtools version fallback mechanism to look for an older version when mismatch occurs (#10749)
* Better support for co-operative multi inheritance by utilising super() throughout
* Improved type hints throughout

您现在需要使用：

from selenium.webdriver.common.by import By

driver.find_element(By.CLASS_NAME, THE_CLASS_NAME)

或者没有额外的导入：

driver.find_element("class name", THE_CLASS_NAME)

为了提高可靠性，您应该考虑将

WebDriverWait

与

element_to_be_clickable

结合使用。
