How to Uninstall Flask in Python

Flask is a popular Python web framework. Sometimes, you may need to uninstall it. This guide will help you remove Flask cleanly.

Why Uninstall Flask?

You might need to uninstall Flask for several reasons. Maybe you are switching to another framework like Django. Or you want a fresh install.

Uninstalling Flask ensures no conflicts with other packages. It also helps free up space.

Check Flask Installation

First, check if Flask is installed. Use the pip show command.

 
pip show flask

Name: Flask
Version: 2.0.1
Summary: A simple framework for building complex web applications.

If Flask is installed, you will see its details. If not, you will get a "not found" message.

Uninstall Flask Using Pip

The easiest way to uninstall Flask is using pip uninstall.

 
pip uninstall flask

This will remove Flask and its dependencies. Confirm the action when prompted.

Verify Uninstallation

After uninstalling, verify Flask is removed. Use the pip show command again.

 
pip show flask

Package 'flask' not found.

This confirms Flask is no longer installed.

Remove Residual Files

Sometimes, pip leaves residual files. Check your Python site-packages directory.

Navigate to the directory and delete any Flask-related folders.

 
ls /path/to/python/site-packages | grep flask

Delete any folders or files related to Flask.

Reinstall Flask (Optional)

If you need Flask again, reinstall it using pip.

 
pip install flask

This will install the latest version of Flask.
