Selenium - Python：'WebDriver‘对象没有属性'find_element_by_name’
Selenium - Python：'WebDriver‘对象没有属性'find_element_by_name’
提问于 2022-06-27 13:48:31
我正试图让Selenium使用Chrome，但我经常遇到这样的错误消息(以及其他类似的错误消息)：
AttributeError: WebDriver对象没有属性“find_element_by_name”
find_element_by_id()、find_element_by_class()等也会出现同样的问题。
我也不能给send_keys()打电话。
我只是在运行https://chromedriver.chromium.org/getting-started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GoogleChromeVersion103.0.5060.53，并从https://chromedriver.chromium.org/downloads下载了https://chromedriver.chromium.org/downloads 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.

我不认为DevTools监听部分与问题有关，但我想我会包括它，以防万一。

Selenium刚刚删除了4.3.0版本中的该方法。参见更改：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")在你的例子中，它将变成：
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。
