selenium-webdriver selenium-chromedriver

Question

Soy un novato en webscraping, estoy tratando de modificar mi agente de usuario usando estas líneas:

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)

La ruta en la variable de entorno está bien, pero sigo teniendo este mensaje de error:

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:

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

¿Puedes ayudarme por favor a solucionar este problema?

Answer 1

Este mensaje de error ...

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

... implica que ChromeDriver no se encontró dentro de las ubicaciones especificadas dentro de la variable PATH dentro de las Variables de entorno .

Solución

Debe pasar la ruta ejecutable clave junto con el valor que se refiere a la ruta absoluta de ChromeDriver junto con el objeto ChromeOptions como argumento al inicializar WebDriver y WebBrowser de la siguiente manera:

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'')
