How can I troubleshoot and resolve the issue of “cannot find chrome binary”?

229    Asked by Deepabhawana in QA Testing , Asked on May 23, 2024

I am currently engaged in a particular task related to developing a web scraping script using the selenium in Python programming language on my local machine. While running my script, I encountered the error message “cannot find chrome binary”. Describe the steps for me of how can I troubleshoot and resolve this particular issue.

In the context of selenium, here are the steps given:-

Verify the Chrome installation

You should try to ensure that the google chrome should be installed on your system. You can check this by opening Chrome manually or just you can search for it in your system application.

Locate the Chrome binary path

You can find the path to the Chrome binary. For example in Windows “C:Program FilesGoogleChromeApplicationChrome.exe”.

Setting the Chrome binary path in your script

You should Configure your Selenium web driver to use the correct path to the Chrome library. This can be done by using the technique of setting the “binary_location” in the “ChromeOptions”.

Coding implementation

Here is a Python example given below of how you can set the binary path in your particular Selenium script:-

From selenium import webdriver
From selenium.webdriver.chrome.service import Service
From selenium.webdriver.chrome.options import Options
# Path to ChromeDriver executable
Chromedriver_path = ‘/path/to/chromedriver’
# Path to Chrome binary
Chrome_binary_path = ‘/path/to/chrome’
# Set up Chrome options
Chrome_options = Options()
Chrome_options.binary_location = chrome_binary_path
# Create a new Chrome service
Chrome_service = Service(chromedriver_path)
# Initialize the WebDriver with the service and options
Driver = webdriver.Chrome(service=chrome_service, options=chrome_options)
# Your web scraping logic here
Driver.get(‘http://example.com’)
# Don’t forget to close the driver after your operations
Driver.quit()

Checking environment variables

You should make sure that the chrome binary path should be included in your system’s PATH environment variable. This would allow the system to locate the Chrome executable globally.

Reinstall or update Chrome and Chromedriver

You should ensure that both the Google Chrome and Chrome drivers are up to date. It is very important because the compatibility issues can sometimes cause such errors. Reinstalling them would also help if there are any corruptions.

Therefore, by following these steps you can resolve the “cannot find chrome binary” error and successfully run your selenium’s script.

Import os

  • From selenium import webdriver
  • From selenium.webdriver.chrome.service import Service
  • From selenium.webdriver.chrome.options import Options
  • From selenium.common.exceptions import WebDriverException

Def main():
    # Path to ChromeDriver executable
    Chromedriver_path = ‘/path/to/chromedriver’ # Update this with your actual ChromeDriver path
    # Path to Chrome binary
    Chrome_binary_path = ‘/path/to/chrome’ # Update this with your actual Chrome binary path
    # Verify that the ChromeDriver exists at the specified path
    If not os.path.exists(chromedriver_path):
        Print(f”Error: ChromeDriver not found at {chromedriver_path}”)
        Return
    # Verify that the Chrome binary exists at the specified path
    If not os.path.exists(chrome_binary_path):
        Print(f”Error: Chrome binary not found at {chrome_binary_path}”)
        Return
    Try:
        # Set up Chrome options
        Chrome_options = Options()
        Chrome_options.binary_location = chrome_binary_path
        # Create a new Chrome service
        Chrome_service = Service(chromedriver_path)
        # Initialize the WebDriver with the service and options
        Driver = webdriver.Chrome(service=chrome_service, options=chrome_options)
        # Navigate to a web page
        Driver.get(‘http://example.com’)
        Print(“Page title is:”, driver.title)
        # Additional web scraping or automation logic can be added here
        # …
    Except WebDriverException as e:
        Print(f”WebDriverException occurred: {e}”)
    Finally:
        # Ensure the driver quits regardless of success or failure

        Try:

            Driver.quit()
        Except UnboundLocalError:
            # Handle the case where ‘driver’ was never initialized
            Print(“Driver was not initialized, nothing to quit.”)
If __name__ == “__main__”:
    Main()
