Blender is bundled with a version of BAM.
To update this version, first build a new wheel <http://pythonwheels.com/>
_ file in
BAM itself:
python3 setup.py bdist_wheel
Then copy this wheel to Blender:
cp dist/blender_bam-xxx.whl /path/to/blender/release/scripts/addons/io_blend_utils/
Remove old wheels that are still in /path/to/blender/release/scripts/addons/io_blend_utils/
before committing.
This is the way that Blender runs bam-pack:
PYTHONPATH=./path/to/blender_bam-xxx.whl python3 -m bam.pack
