Fix PIL Imaging Backend Error | Generated by AI

Home 2025.08

This error means your PIL installation is either missing its binary backend (_imaging) or you’re accidentally using the old “PIL” package instead of the modern “Pillow.” Here’s how to fix it:

  1. Make sure you’re on Python 3 If python is pointing at Python 2, switch to Python 3:

    python3 --version
    python3 scripts/content/avatar.py
    
  2. Uninstall any stale PIL package

    # this removes the old PIL if it’s installed via pip
    python3 -m pip uninstall -y PIL
    
  3. (Re)install Pillow

    python3 -m pip install --upgrade --force-reinstall pillow
    
  4. Install required system libraries On Ubuntu you’ll need the imaging headers so Pillow can build its _imaging extension:

    sudo apt update
    sudo apt install -y libjpeg-dev zlib1g-dev
    # then reinstall Pillow so it recompiles against those libs
    python3 -m pip install --upgrade --force-reinstall pillow
    
  5. Use a virtual-environment (optional but recommended)

    python3 -m venv .venv
    source .venv/bin/activate
    pip install pillow
    python scripts/content/avatar.py
    

After that, from PIL import Image should work without the _imaging import error.
