How to Resolve Common Selenium Errors in Python Web Crawlers

1. Introduction

Hello everyone, I am Pipi. A few days ago a member of the Python Starry Chat group asked about a Python web‑crawling problem. Below is the screenshot of the error.

2. Implementation Process

One contributor, dcpeng, suggested a solution. The first method is shown in the following image.

The second method is to roll back the Selenium version.

Note that the Selenium version must match the driver version.

Rolling back is straightforward: uninstall the current version and reinstall the compatible one.

Another contributor, error, provided a code snippet that satisfies the requirement:

from selenium.webdriver.common.by import By
print(browser.find_element(By.XPATH, '//*[@id="userName"]'))

The above code works as expected.

3. Summary

This article identified a Python web‑crawling issue, explained the root cause related to Selenium and driver version mismatches, and offered concrete solutions including version rollback and a functional code example to help readers resolve the problem.
