In this article, we will discuss the solutions to the error Modulenotfounderror: no module named webdriver_manager.
The error no module named webdriver_manager occurs if the system cannot find the installation of webdriver_manager
Otherwise, it is not compatible the python version.
How to solve the no module named webdriver_manager?
To install webdriver-manager package, type the following command below:
pip install webdriver-manager
If the error will continue, type the following command below:
pip install webdriver_manager
The ModuleNotFoundError: No module named “webdriver-manager” error will be resolved after installing the webdriver-manager Python library.
Common Error Occurs:
- There is no webdriver_manager module installed in your system.
- Installing the module in a various Python version than the one you’re currently using.
- Installing the module globally and it is not installed in your virtual environment.
- Executing the IDE which is not the correct version of Python.
Check your Python version to make sure you are installing the package using the correct version of Python if the error will continue.
To find out that you already install the webdriver-manager you are running, type this command:
pip show webdriver_manager
The command’s output will look like this after you type it:
Diagnostic checklist for “No module named ‘webdriver_manager'”
- Verify pip install target. Run
pip show webdriver_manager— if not installed, runpip install webdriver_manager. - Check the active Python interpreter.
which python(mac/Linux) orwhere python(Windows). Both pip and python must point to the same environment. - Check virtual environment activation. If you use venv/conda, activate before installing:
source .venv/bin/activate. - Rule out uppercase/lowercase. Python imports are case-sensitive:
import PyPDF2notimport pypdf2. - Rule out the pip-vs-package-name mismatch. Some packages install under a different name than you import (e.g.
pip install beautifulsoup4→import bs4).
Installing webdriver_manager
# Standard pip install pip install webdriver_manager # In a virtual environment (recommended) python -m venv .venv source .venv/bin/activate # or .venv\Scripts\activate on Windows pip install webdriver_manager # With uv (faster alternative) uv pip install webdriver_manager
Common causes for “No module named ‘webdriver_manager'”
- Python interpreter mismatch. Multiple Python installations can confuse pip. Verify with
which pythonandwhich pip. - Virtual environment not activated. If the venv isn’t activated, pip installs to your system Python instead.
- Notebook kernel mismatch. Jupyter uses a kernel that may differ from your terminal Python. Use
%pip install webdriver_managerinside the notebook. - Import name differs from install name. pip install beautifulsoup4 → import bs4. Check the package’s PyPI page.
- Windows PATH issues. Ensure Python is on PATH; use
python -m pip installto invoke pip via the correct Python.
Working code example
# Verify install worked import webdriver_manager print(getattr(webdriver_manager, '__version__', 'no version attribute'))
Best practices
- Always use a virtual environment. Avoids most module-not-found errors.
- Use pip freeze to lock versions.
pip freeze > requirements.txtmakes your setup reproducible. - Consider uv or Poetry. Modern package managers with better dep resolution and reproducibility.

Frequently Asked Questions
What is Python ModuleNotFoundError and what causes it?
ModuleNotFoundError (a subclass of ImportError) is raised when Python cannot find the module you tried to import. Common causes: the package isn’t installed (pip install missing), wrong virtual environment activated, typo in module name, or Python can’t find your local module on the import path. The error message names exactly which module is missing.
How do I fix ‘ModuleNotFoundError: No module named X’?
Run pip install X first. If that succeeds but you still get the error, check which Python you’re using (which python OR python –version) vs which pip (which pip OR pip –version), they must match. Common gotcha: pip points to system Python 3.9 but you’re running python3.11 in a venv. Inside the venv, use python -m pip install X to be sure pip matches the active Python.
Why does my code work in one environment but not another?
Different Python versions or different installed packages. To diagnose: pip freeze > requirements.txt on the working environment, then pip install -r requirements.txt on the broken one. Use virtualenv (python -m venv venv) or conda for every project to avoid system-wide package collisions.
Is ModuleNotFoundError the same as ImportError?
ModuleNotFoundError is a subclass of ImportError added in Python 3.6. It specifically means ‘no such module exists.’ Plain ImportError covers a wider set: module exists but a name inside it can’t be imported (e.g. ‘cannot import name X from Y’). except ImportError catches both; except ModuleNotFoundError catches only the missing-module case.
Where can I find more ModuleNotFoundError fixes?
Browse the ModuleNotFoundError reference hub for 198+ specific module fixes (TensorFlow, Flask, Django, pandas, numpy, etc.). For related issues see ImportError. For broader Python setup see Python Tutorial hub.
