Flask is a micro web framework written in Python. It’s designed to make getting started quick and easy, with the ability to scale up to complex applications. However, there might be instances where you need to uninstall Flask from your Ubuntu system, perhaps to reinstall it, free up space, or switch to another framework.
This guide will walk you through the steps to uninstall Flask from your Ubuntu host.
Let’s get started.
Step 1: Determine Flask Installation Method
Before you can uninstall Flask, you need to determine how it was installed. Flask can be installed using pip, pip3, or as part of a virtual environment.
Step 2: Deactivate Virtual Environment (If Applicable)
If Flask was installed within a virtual environment, deactivate it first:
deactivate
Step 3: Uninstall Flask Using pip or pip3
If Flask was installed using pip or pip3, you can uninstall it using the following command:
pip uninstall Flask
Or, if you used pip3:
pip3 uninstall Flask
Step 4: Confirm Uninstallation
To ensure Flask has been uninstalled, you can try importing it in a Python shell:
python >>> import Flask
If you receive an error stating that Flask is not found, it confirms the uninstallation.
Step 5: Remove Associated Directories (Optional)
If you want to remove all traces of Flask, you can delete its associated directories. However, be cautious as this might remove other packages or configurations:
rm -rf ~/.local/lib/pythonX.X/site-packages/Flask*
Replace X.X with your Python version, e.g., 3.8.
Commands Mentioned
- deactivate – Deactivates the virtual environment.
- pip uninstall Flask – Uninstalls Flask using pip.
- pip3 uninstall Flask – Uninstalls Flask using pip3.
- rm -rf ~/.local/lib/pythonX.X/site-packages/Flask* – Removes Flask associated directories.

What’s the difference between pip and pip3?
pip is for Python 2, while pip3 is for Python 3. It’s essential to use the correct version to manage packages for the respective Python version.
-
Can I uninstall Flask from a specific virtual environment only?
Yes, if Flask is installed in a virtual environment, activating that environment and running the uninstall command will remove it only from that specific environment.

Will uninstalling Flask affect other Python packages?
Uninstalling Flask using pip or pip3 will not affect other Python packages. However, manually deleting directories might, so always proceed with caution.
Conclusion
Uninstalling Flask from your Ubuntu system is a straightforward process, but it’s essential to follow the steps carefully to ensure you don’t inadvertently remove other necessary packages or configurations. Whether you’re looking to free up space, resolve conflicts, or transition to another framework, this guide provides a step-by-step approach to help you achieve your goal.
