🔧 How to Fix “ModuleNotFoundError” in Python on Kali Linux (2025 Easy Fix)

Encountering ModuleNotFoundError in your Python scripts on Kali Linux in 2025? It’s one of the most frustrating errors when your code can’t find required packages. This guide shows you how to identify, troubleshoot, and fix this issue quickly.

⚠️ What Causes ModuleNotFoundError?

• The Python module/package is not installed on your system.
• Installed module is for a different Python version (Python 2 vs 3).
• Virtual environment issues where the package isn’t installed inside the environment.
• Wrong Python interpreter is used to run the script.
• Misconfigured PYTHONPATH or environment variables.

✅ Step 1: Identify the Missing Module

Look at the error message carefully. It will say which module is missing, e.g.,

ModuleNotFoundError: No module named 'requests'

🔧 Step 2: Check Python Version

Confirm which Python version you are running:

python --version
python3 --version

Kali usually uses Python 3, so prefer python3 commands.

🔧 Step 3: Install the Module Using Pip

Install the missing package using pip for Python 3:

sudo apt update
sudo apt install python3-pip
pip3 install requests

Replace requests with your missing module.

⚡ Step 4: Use Virtual Environments to Avoid Conflicts

Create and activate a virtual environment to isolate dependencies:

python3 -m venv myenv
source myenv/bin/activate
pip install requests

Run your script inside this environment to avoid system-wide conflicts.

🔍 Step 5: Check Your Script’s Interpreter

Ensure your script uses the correct shebang:

#!/usr/bin/env python3

This forces the script to run with Python 3, which is often required for newer modules.

🧠 Pro Tips

• Use pip3 list to verify installed modules.
• Upgrade pip regularly with pip3 install --upgrade pip.
• For global installs, prefer sudo pip3 install, but virtual environments are safer.
• If you have multiple Python versions, specify the pip for your version explicitly.

💬 Troubleshooting

Error: “pip command not found”

Fix: Install pip using sudo apt install python3-pip.

Error: Still getting ModuleNotFoundError after install

Fix: Verify you’re running the script with the Python version where the module is installed.

📌 Final Thoughts

“ModuleNotFoundError” is a straightforward fix once you understand Python environment management on Kali Linux. Installing the correct packages and using virtual environments will save you hours of headaches.
