我试图让Selenium与Chrome一起工作,但我一直遇到这个错误消息(以及其他类似的消息):
属性错误:“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。
我也不能调用send_keys()
我只是在运行 ChromeDriver - WebDriver for Chrome - 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.

我不认为DevTools监听部分与这个问题有关,但我想我会包括它,以防万一。

Selenium在4.3.0版本中删除了这个方法。看看变化: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

您现在需要用途:

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WebDriverWaitelement_to_be_clickable结合使用。

您需要使用以下代码导入Selenium WebDriver:

from selenium.webdriver.common.by import By

接下来使用这个API:
| 旧API|新API|
| --|--|
| find_element_by_id('id ')|find_element(By.ID,'id')|
| find_element_by_name('name ')|find_element(By.NAME,'name')|
| find_element_by_xpath('xpath ')|find_element(By.XPATH,'xpath')|

find_element_by_* 和find_elements_by_* 已弃用。可以使用 find_element() 代替。
首先,你需要导入:

from selenium.webdriver.common.by import By

然后你可以使用它与:

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

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

等等。查看find_element()API了解所有用法

感谢michael-mintz和federikowsky给出了根本原因的线索。
在我的例子中,我无法编辑代码以与最新的Selenium版本兼容。因此,作为一种变通方法,我将Selenium降级到4.2.0。
对于Python 3:
1.请确保您的Selenium是4.3.0或更高版本。启动Python交互式会话并运行:

>>> import selenium
>>> selenium.__version__

1.降级您的Selenium

  • 编辑依赖项文件(requirements.txt)并提及特定版本:
selenium==4.2.0
  • 或者,如果您无法更改依赖项文件(requirements.txt),请运行以下命令:
pip3 install -r requirements.txt
pip3 uninstall selenium
pip3 install selenium==4.2.0
