Py pip

py-pip lets you install Python packages from inside a Python environment. e.g. in Blender, Maya, Max, …

The difference with existing solutions, py-pip solves an issue with the environment:

• Blender ships with various python packages pre-installed in it’s python\lib folder.
  But pip is not aware of these, e.g. the venv package ships with Blender, but when running pip show venv it doesn’t detect it.
• Also, any python paths added after Blender startup won’t be detected by pip. e.g. various modules in the user site packages are added on startup.
  If pip can’t detect installed packages, it can result in packages being installed twice.

• plugget - create a self-installing plugin
  • replaced plugget vendor with Unreal dependencies installer, which uses py-pip, a simpler solution for Unreal. Less good for plugget.
    But plugget has more dependencies, and the extra 3 Mb vendor size seems too bloated.
• Unreal dependencies installer
  • Auto install Python module dependencies in Unreal, using py-pip.
  • The dependencies installer tries to install dependencies every time on startup. It would be nicer to only try once.
    AFAIK plugget already did both, installing dependencies only once, and skipping install if already installed. But it’s less drag and drop, requiring the user to first setup plugget.
• expose a python tool in plugget without wrapping it
  • still getting problems installing the dependencies. PySide6_examples tries to install PySide6 which is already in use by the plugget qt tool. py-pip doesn’t install already installed tools, however it doesn’t handle dependencies of dependencies atm.
• plugget - create a self-installing plugin brainstorm
  • plugget’s _requirements.py action already vendors py-pip, see code
    This approach doesn’t handle any module reload.
• unreal-pip
  • [!warning]
  • unreal-pip is a single file, so easy to vendor. (just like py-pip atm)
    py-pip is generic, and its settings aren’t configured for Unreal. Plugget contains those settings in its unreal install action.
