【问题描述】：

我正在尝试让 Selenium 与 Chrome 一起使用，但我一直遇到此错误消息（以及其他类似的错误消息）：

AttributeError: 'WebDriver' object has no attribute 'find_element_by_name'

find_element_by_id()、find_element_by_class() 等也会出现同样的问题。

我也打不通send_keys()。

我只是运行这里提供的测试代码：https://chromedriver.chromium.org/getting-started

import time

from selenium import webdriver



driver = webdriver.Chrome("C:/Program Files/Chrome Driver/chromedriver.exe")  # Path to where I installed the web driver

driver.get('http://www.google.com/');

time.sleep(5) # Let the user actually see something!

search_box = driver.find_element_by_name('q')

search_box.send_keys('ChromeDriver')

search_box.submit()

time.sleep(5) # Let the user actually see something!

driver.quit()

我使用的是 Google Chrome 版本 103.0.5060.53，并从这里下载了 ChromeDriver 103.0.5060.53：https://chromedriver.chromium.org/downloads

运行代码时，Chrome 会打开并导航到 google.com，但会收到以下输出：

C:\Users\Admin\Programming Projects\Python Projects\Clock In\clock_in.py:21: DeprecationWarning: executable_path has been deprecated, please pass in a Service object
  driver = webdriver.Chrome("C:/Program Files/Chrome Driver/chromedriver.exe")  # Optional argument, if not specified will search path.

注意：我替换了这篇文章的文件路径。

我认为 DevTools 监听部分与该问题无关，但我想我会包括它，以防万一。

【解决方案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

你现在需要使用：

driver.find_element("name", "q")

在您的示例中，它将变为：

search_box = driver.find_element("name", "q")

search_box.send_keys('ChromeDriver')

search_box.submit()

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