Why Does My Python Selenium Script Fail with 'chromedriver' executable needs to be in PATH'?

Resolving 'chromedriver' Executable Not Found in PATH Error with Headless Chrome

Python scripts often encounter an error when executing headless Chrome using Selenium due to the 'chromedriver' executable not being recognized in the PATH.

To analyze the issue, we examine the error log:

selenium.common.exceptions.WebDriverException: Message: 'chromedriver' executable needs to be in PATH. Please see https://sites.google.com/a/chromium.org/chromedriver/home

The error suggests that the Python client cannot locate the chromedriver binary. To resolve this, we need to address the following points:

• chrome_options.binary_location: This parameter points to the chrome.exe, not chromedriver.exe.
• os.path.abspath("chromedriver"): This picks up the path to chromedriver, but does not append chromedriver.exe.

Here's a revised code sample to effectively launch Google Chrome in headless mode:

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

chrome_options = Options()  
chrome_options.add_argument("--headless")  
driver = webdriver.Chrome(chrome_options=chrome_options, executable_path=r'C:\Utility\BrowserDrivers\chromedriver.exe')  
driver.get("http://www.duo.com") 
print("Chrome Browser Initialized in Headless Mode")
driver.quit()
print("Driver Exited")
