[SOLVED] ModuleNotFoundError: No Module Named Selenium

The error message “ModuleNotFoundError: No module named ‘selenium'” indicates that the Selenium package is not installed in your Python environment. To resolve this issue, you can follow these steps:

  • Make sure you have Python installed on your system. You can check by running python –version in your terminal or command prompt.
python --version
  • Install Selenium using pip (or pip3), which is the package manager for Python. Open your terminal or command prompt and run the following command:
pip3 install selenium
  • This command will download and install the Selenium package along with its dependencies.
  • Once the installation is complete, you can import and use the Selenium module in your Python scripts without encountering the “ModuleNotFoundError” exception.

If you’re using a virtual environment, activate it before running the installation command to ensure that Selenium is installed within the correct environment.

If you already have Selenium installed but are still encountering the error, it’s possible that you have multiple Python installations or environments, and the module is installed in a different one. In that case, you may need to check your Python paths or ensure that you execute your script in the correct environment where Selenium is installed.

The Python Selenium Module

The Python Selenium module is a library that automates web browser interactions and testing. It provides bindings to the Selenium WebDriver API, allowing developers to programmatically control web browsers and simulate user actions such as clicking, filling out forms, and navigating. It’s commonly used for web testing, cross-browser testing, web scraping, and data extraction. Selenium’s integration with testing frameworks and support for headless browsing make it a versatile tool for automating web-related tasks and ensuring the functionality of web applications.

Here’s a simple example of using the Python Selenium module to open a webpage, input text into a search bar, and click the search button using the Chrome WebDriver:

from selenium import webdriver
from selenium.webdriver.common.keys import Keys

# Create a Chrome WebDriver instance
driver = webdriver.Chrome()

# Open a webpage

# Find the search bar element and input text
search_bar = driver.find_element_by_name("q")
search_bar.send_keys("Selenium automation")

# Simulate pressing Enter in the search bar

# Close the browser
