Issues

"ModuleNotFoundError" when running the script in Blender:

Blender does not use the same Python environment as your system. You need to install the required packages in Blender's Python environment.

1. First, find your Blender's Python executable. You can find this in the Blender console when you open Blender. It should be something like /Applications/Blender.app/Contents/Resources/2.93/python/bin/python3.9. Mine was /Applications/Blender/Contents/Resources/4.2/python/bin/python3.11

2. Create a temporary directory anywhere mkdir tmp and go into it cd tmp. This is where you will install the required packages.

3. Create a virtual environment python -m venv myenv

4. Activate the virtual environment source myenv/bin/activate

5. Install the required packages (websockets and qrcode) in our temporary directory: Applications/Blender/Contents/Resources/4.2/python/bin/python3.11 -m pip install websockets qrcode"[pil]" -t . IMPORTANT: Make sure you are using blender's python executable as some packages have binaries tied to the python version.

6. Copy the installed packages to Blender's Python environment. Here's what I did:

   • In the tmp directory, I ran open . to open the directory in Finder.
   • I went to /Applications/Bl/Contents/Resources/4.2/python/lib/python3.11 and ran open . to open the directory in Finder.
   • I dragged websockets, qrcode, and PIL from the tmp directory to the other

7. Cleanup the temporary directory cd .. and rm -rf tmp

8. Quit and reopen Blender. Paste and run the script again.
