Question

我是webscraping的新手，我正在尝试使用以下行修改我的用户代理：

from selenium import webdriver
chrome_path = r'C:\Users\Desktop\chromedriver_win32\chromedriver.exe'   
driver = webdriver.Chrome(chrome_path)
options = webdriver.ChromeOptions()
options.add_argument('user-agent = Mozilla/5.0 (Windows NT 6.1) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/41.0.2228.0 Safari/537.36')
driver = webdriver.Chrome(chrome_options=options)

环境变量中的路径没问题，但我一直有这样的错误消息：

File "C:\Users\AppData\Local\Programs\Python\Python36-32\lib\site-packages\selenium\webdriver\common\service.py", line 76, in startstdin=PIPE)
File "C:\Users\AppData\Local\Programs\Python\Python36-32\lib\subprocess.py",line 709, in __init__restore_signals, start_new_session)
File "C:\Users\AppData\Local\Programs\Python\Python36-32\lib\subprocess.py",line 997, in _execute_child startupinfo).
During handling of the above exception, another exception occurred:
Traceback (most recent call last):
File "C:\Users\safia\AppData\Local\Programs\Python\Python36-32\Test 3- User Agent.py", line 9, in <module>
driver = webdriver.Chrome(chrome_options=options)

self.service.start()

os.path.basename(self.path), self.start_error_message)
selenium.common.exceptions.WebDriverException: Message: 'chromedriver' executable needs to be in PATH. Please see https://sites.google.com/a/chromium.org/chromedriver/home

你能帮我解决这个问题吗？

Answer 1

此错误消息......

selenium.common.exceptions.WebDriverException: Message: 'chromedriver' executable needs to be in PATH

...表示在环境变量中的 PATH 变量中指定的位置内找不到 ChromeDriver 。

解决方案

您需要传递键 executable_path 以及值，并参考 ChromeDriver的绝对路径以及 ChromeOptions 对象作为参数，同时初始化 WebDriver 和 WebBrowser ，如下所示：

from selenium import webdriver

options = webdriver.ChromeOptions()
options.add_argument('user-agent = Mozilla/5.0 (Windows NT 6.1) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/41.0.2228.0 Safari/537.36')
driver = webdriver.Chrome(chrome_options=options, executable_path=r'C:\Users\Desktop\chromedriver_win32\chromedriver.exe')
driver.get('https://www.google.co.in')

WebDriverException：消息：'chromedriver'可执行文件需要在PATH中，同时通过Selenium Chromedriver Phyton设置UserAgent
