When working with keyboard and mouse automation in Python, you might encounter the error "No module named pynput". This error occurs when the pynput module isn't properly installed in your Python environment.

Understanding the Error

The error typically appears when you try to import the pynput module in your Python script without having it installed. Here's an example of code that would trigger this error:

from pynput import keyboard
from pynput import mouse

# This will raise ImportError: No module named pynput

ImportError: No module named pynput

How to Fix the Error

The most common solution is to install pynput using pip. You can learn more about the installation process in our detailed Python Pynput Installation Guide.

Common Installation Issues and Solutions

Sometimes, the basic installation might not work due to various reasons. Here are some alternative approaches:

1. Using Python Version-Specific pip

python -m pip install pynput
# OR
python3 -m pip install pynput

2. Installing in Virtual Environment

python -m venv myenv
source myenv/bin/activate  # On Windows: myenv\Scripts\activate
pip install pynput

Verifying the Installation

After installation, you can verify if pynput is properly installed by running this simple test code:

from pynput import keyboard

def on_press(key):
    print(f'Key {key} pressed')
    if key == keyboard.Key.esc:
        return False

# Create a keyboard listener
with keyboard.Listener(on_press=on_press) as listener:
    listener.join()

# Press ESC to exit

Troubleshooting Tips

If you're still experiencing issues, try these troubleshooting steps:

1. Check your Python environment path using sys.executable

2. Verify pip installation with pip --version
