Why Does Selenium Throw a NoSuchDriverException and How Can I Fix It?

Resolving Webdriver Exceptions: Troubleshooting NoSuchDriverException

When attempting to create an object using Selenium Webdriver, you may encounter the following error:

selenium.common.exceptions.NoSuchDriverException: Message: Unable to obtain <path-to-chromedriver> using Selenium Manager; 'str' object has no attribute 'capabilities';

Error Analysis

This error message indicates that the Selenium Manager is unable to locate the correct path to the browser driver, in this case, the chromedriver. As a result, the Selenium operation fails to initialize the browser, raising the NoSuchDriverException.

Root Cause

The root cause of this error is often related to an incorrect Selenium version or an outdated Selenium Manager.

Solution

To resolve this issue, follow these steps:

1. Check Selenium Version

Ensure that you are using Selenium v4.6.0 or above. In v4.6.0, Selenium introduced the Selenium Manager, which automatically handles driver management instead of relying on traditional path configuration.

2. Update Selenium Manager

If you are using Selenium v4.6.0 or above, try updating the Selenium Manager to the latest version. This can be done using the following command:

pip install -U selenium-webdriver

3. Simplified Code

Once the Selenium Manager is updated, you can simplify your code as follows:

from selenium import webdriver

driver = webdriver.Chrome()
driver.get("https://www.google.com/")
driver.quit()
