Why am I getting the 'No module named 'selenium'' error in Python?

"No module named 'selenium'" Issue in Python

Python users may encounter the error "No module named 'selenium'" when attempting to import the Selenium library. This error indicates that the library is not properly installed or configured within the Python environment.

To resolve this issue, follow these steps:

1. Verify Python Version

Confirm that you are using Python 3.6 or later, as Selenium is not compatible with earlier versions.

2. Install Selenium

Download Selenium for Python from PyPI: https://pypi.org/project/selenium/. Next, install it using pip:

python -m pip install -U selenium

3. Check Pip

Ensure Pip is properly installed and up-to-date:

pip --version

4. Install Other Dependencies

Selenium requires additional dependencies such as a browser driver, which may not be installed automatically. Consult Selenium's documentation for specific driver requirements.

5. Configure IDE

If using an IDE, configure it to include the Selenium libraries in its search path. This allows the IDE to recognize and import Selenium modules.

6. Webdriver Location

If you encounter this error when using a specific browser driver, ensure that the driver path is correctly configured. One common instance is with the GeckoDriver for Firefox:

from selenium.webdriver.firefox.options import Options
from selenium.webdriver.firefox.service import Service

options = Options()
service = Service("C:/path/to/geckodriver.exe") # Replace with actual path
driver = webdriver.Firefox(options=options, service=service)

These steps should resolve the "No module named 'selenium'" error and allow you to successfully import and use the Selenium library in your Python code.
