Ubuntu下Manim运行报错：无法从PIL导入_imaging的解决咨询

Hey there, let's work through this PIL/Pillow issue you're facing with Manim. I've run into similar dependency quirks before, so here's a step-by-step breakdown to get you back up and running:

First, correct the import mistake in camera.py #

You mentioned changing the import to from pillow import Image—that's the wrong module name! Pillow is a drop-in replacement for PIL, but you still import it using PIL as the module name. Revert that line in camera.py back to:

from PIL import Image

Step 1: Ensure Pillow is installed for your specific Python 3.7 environment #

It's common to have multiple Python versions on Ubuntu, so even if pip says Pillow is installed, it might be linked to a different Python version. Let's explicitly target Python 3.7:

1. Uninstall any existing Pillow installations tied to Python 3.7:

   python3.7 -m pip uninstall -y Pillow
   

2. Install a Pillow version that's fully compatible with Python 3.7 (v8.4.0 is a reliable choice):

   python3.7 -m pip install Pillow==8.4.0
   

Step 2: Fix missing system dependencies (if installation was incomplete) #

Sometimes Pillow fails to compile its native extensions (like _imaging) on Ubuntu because of missing system libraries. Install the required dev packages first:

sudo apt-get update && sudo apt-get install python3.7-dev libjpeg-dev zlib1g-dev

Then reinstall Pillow with no cache to ensure a fresh build:

python3.7 -m pip install Pillow==8.4.0 --no-cache-dir

Step 3: Verify the fix works #

Test if PIL imports correctly in your Python 3.7 environment:

python3.7 -c "from PIL import Image; print(f'Pillow version: {Image.__version__}')"

If this prints the version number without errors, you're good to go. Now try running your Manim command again:

python3.7 -m manim example_scenes.py SquareToCircle -pl

Bonus check: Virtual environment sanity #

If you're using a virtual environment for Manim, make sure you activate it before running any pip or python3.7 commands. A common mistake is installing packages in the global environment while using a virtual one.
