[chimerax-users] Plugin development: how to install python packages

Hello,

I am developing a chimerax plugin. My code will have some interaction with mdtraj. I need mdtraj to be installed in the python that ships with chimerax. I tried "chimerax -m pip install mdtraj" but I get all kinds of error dialogs popping up in the chimerax instance that gets launched during the installation. I terminate all the error dialogs and then exit chimerax (as the python install seems frozen) and then it indeed says installation has failed and gives unusual error messages (like setuptools was less than version 48.0.0 while chimerax reports it to be 65.x.y and even 66.x.y after upgrading).

Can someone tell me the correct syntax to use to install mdtraj in chimerax's python? Thank you.
