selenium.common.exceptions.WebDriverException: Message: unknown error: cannot find Chrome binary
(Driver info: chromedriver=2.43.600210 (68dcf5eebde37173d4027fa8635e332711d2874a),platform=Windows NT 10.0.19042 x86_64)    

Answer 1

you need to install a chrome driver and tell selenium where to find it. by either:

• updating your PATH
• using executable_path when instantiating a new driver

then install chrome and tell chrome driver where to find it.

Answer 2

The message indicate that the chrome driver was either not installed or not found by Python code.

Check the following link to setup chrome drivers:

https://github.com/SeleniumHQ/selenium/wiki/ChromeDriver

The best way is to download the binary from following link:

https://sites.google.com/a/chromium.org/chromedriver/

Once done, you can identify the path to the driver present in the local directory like following:

from selenium import webdriver from selenium.webdriver.chrome.options import Options

options = Options()
options.binary_location = "C:\\Program Files\\Chrome\\chrome64_55.0.2883.75\\chrome.exe"
driver = webdriver.Chrome(chrome_options = options, executable_path=r'C:\path\to\chromedriver.exe')
driver.get('http://google.com/')
print("Chrome Browser Invoked")
driver.quit()

Answer 3

You do not have the driver installed for your browser, or the python code cannot find it. On the official Selenium website you can find detailed instructions for installing the appropriate driver: https://www.selenium.dev/documentation/webdriver/getting_started/install_drivers/ .
