[英]WebDriverException: WebDriverException: Message: 'chromedriver' executable needs to be in PATH
[英]WebDriverException: Message: 'chromedriver' executable needs to be in PATH while setting UserAgent through Selenium Chromedriver python
我是 webscraping 的新手,我正在嘗試使用這些行修改我的用戶代理:
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)
環境變量中的路徑沒問題,但我一直收到此錯誤消息:
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)
File "C:\Users\safia\AppData\Local\Programs\Python\Python36-32\lib\site-packages\selenium\webdriver\chrome\webdriver.py", line 68, in __init__
self.service.start()
File "C:\Users\safia\AppData\Local\Programs\Python\Python36-32\lib\site-packages\selenium\webdriver\common\service.py", line 83, in 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
你能幫我解決這個問題嗎?
此錯誤消息...
selenium.common.exceptions.WebDriverException: Message: 'chromedriver' executable needs to be in PATH
...意味着ChromeDriver未在Environment Variables的PATH變量中指定的位置內找到。
在初始化WebDriver和WebBrowser時,您需要傳遞Key executable_path以及引用ChromeDriver的絕對路徑的Value以及ChromeOptions對象作為參數,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')
