Why Am I Getting a WebDriverException: \'chromedriver\' Executable Not Found in Selenium?

WebDriverException: 'chromedriver' Executable Not Found

Selenium's WebDriverException is a common error when working with Chromedriver. This error occurs when the 'chromedriver' executable is not present in the system's PATH environment variable.

Analyzing the Error

The error is thrown in this specific case because an attempt is being made to modify the user agent using Selenium Chromedriver in Python. The following lines of code are used:

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)

However, the error persists despite setting the correct path for the chromedriver executable.

Solution

The solution to this issue is to pass the 'executable_path' along with the absolute path of the chromedriver executable while initializing the WebDriver. This is done as follows:

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')

By providing the 'executable_path' parameter, the WebDriver is directed to the specific location of the chromedriver executable, resolving the error.
