“没有名为 'selenium.webdriver.common.by' 的模块”Selenium Python 中的错误

Question

我在尝试运行此代码时在 Sublime Text 中得到此输出：

from selenium import webdriver
from selenium.webdriver.common.keys import Keys
import time
PATH = "C:/Users/josh.bailey/Documents/chromedriver.exe"
driver = webdriver.Chrome(PATH)
driver.get ("https://vehicleenquiry.service.gov.uk/")
time.sleep(5)
search = driver.find_element_by_id("wizard_vehicle_enquiry_capture_vrn_vrn")
search.send_keys("*REDACTED*")
search.send_keys(Keys.RETURN)
time.sleep(5)
main = driver.find_element_by_class("reg-mark-sm")
print(main.text)
driver.quit()

这是非常基本的代码，我只是想尝试一些方法，以便在将车辆详细信息输入到我们的数据库时简化业务流程。代码还没有完成，但我只是因为这个错误打印输出而卡住了：

回溯（最近调用最后）：

  File "C:\Users\josh.bailey\Documents\Test3.py", line 2, in <module>
    from selenium import webdriver

  File "C:\Users\josh.bailey\AppData\Roaming\Python\Python38\site- 
    packages\selenium\webdriver\__init__.py", line 18, in <module>
    from .firefox.webdriver import WebDriver as Firefox  # noqa

  File "C:\Users\josh.bailey\AppData\Roaming\Python\Python38\site- 
    packages\selenium\webdriver\firefox\webdriver.py", line 27, in 
    <module>
    from selenium.webdriver.remote.webdriver import WebDriver as 
    RemoteWebDriver
  
  File "C:\Users\josh.bailey\AppData\Roaming\Python\Python38\site- 
    packages\selenium\webdriver\remote\webdriver.py", line 41, in 
    <module>
    from .shadowroot import ShadowRoot

  File "C:\Users\josh.bailey\AppData\Roaming\Python\Python38\site- 
    packages\selenium\webdriver\remote\shadowroot.py", line 21, in 
    <module>
    from ..common.by import By

ModuleNotFoundError: No module named 'selenium.webdriver.common.by'
[Finished in 195ms]

在selenium\webdriver\common目录下肯定有一个by.py文件，就像有一个keys.py文件一样。我打开了 by.py 文件，它似乎包含了它应该包含的所有内容。我做错了什么吗？任何帮助，将不胜感激。谢谢！

您好，请更正该行 "find_element_by_class_name"

main = driver.find_element_by_class("reg-mark-sm")

to 

main = driver.find_element_by_class_name("reg-mark-sm")

这里是完整的代码

from selenium import webdriver
from selenium.webdriver.common.keys import Keys
import time

PATH = "C:/Users/josh.bailey/Documents/chromedriver.exe"
driver = webdriver.Chrome(PATH)
driver.get ("https://vehicleenquiry.service.gov.uk/")
time.sleep(5)
search = driver.find_element_by_id("wizard_vehicle_enquiry_capture_vrn_vrn")
search.send_keys("*REDACTED*")
search.send_keys(Keys.RETURN)
time.sleep(5)
main = driver.find_element_by_class_name("reg-mark-sm")
print(main.text)
driver.quit()
