Selenium - Python - AttributeError：“WebDriver”对象没有属性“find_element_by_name”

Question

我试图让 Selenium 与 Chrome 一起工作，但我一直遇到此错误消息（以及其他类似消息）：

AttributeError: ‘WebDriver’ 对象没有属性 ‘find_element_by_name’

同样的问题发生在 find_element_by_id() , find_element_by_class() 等。

我也无法调用 send_keys() 。

我只是在运行 ChromeDriver - WebDriver for Chrome - Getting started 中提供的测试代码。

 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 Downloads 下载了 ChromeDriver 103.0.5060.53。

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

 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。

我不认为 DevTools 监听部分与该问题相关，但我想我会包括它，以防万一。

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：

 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，您应该考虑结合使用 WebDriverWait 和 element_to_be_clickable 。

Answer 2

find_elementby* 和 find_elementsby* 已弃用。您可以改用 _find_element()_ 。

首先你必须导入：

 from selenium.webdriver.common.by import By

然后你可以使用它：

 driver.find_element(By.XPATH, " ")
driver.find_elements(By.XPATH, " ")

driver.find_element(By.CLASS_NAME, " ")
driver.find_elements(By.CLASS_NAME, " ")

等.. 查看所有用法的 find_element() API
