Another possibility, is that if you create the wheel first with "setup.py bdist_wheel", then "chimerax -m pip install --user NAME.whl" will install it in your personal extensions to ChimeraX.     -- Greg On 8/17/2023 4:27 PM, Eric Pettersen via ChimeraX-users wrote:

Hi Barry, The problem is that ChimeraX is installed as root on Linux and that a simple “setup.py install” tries to install into the app, which it does not have permission for.  You need to get it to install into a user-owned area that ChimeraX looks at for modules.  That directory is contained in chimerax.app_dirs.user_data_dir.  You get setup.py to install there with “setup.py install —home=/value-from-app_dirs/”.

Thanks for the help Eric.

I am pretty close to everything working but I think this traj2nmr install approach might be a dead end.

In my chimerax tool I have this at the beginning:

if importlib.util.find_spec('traj2nmr') is None:     app_dir = pathlib.Path(__file__).parent.resolve()

subprocess.run(["python3", app_dir / 'Installable' / 'install_traj2nmr.py', sys.executable])

Then in my install_traj2nmr.py file that gets called by the above code I have this:

this_files_dir = pathlib.Path(__file__).parent.resolve()

chimerax = sys.argv[1]

os.system(f"cd {this_files_dir}/traj2nmr; {chimerax} --nogui --script 'setup.py install' --exit")

And it ALMOST works. Unfortunately it seems that I might need sudo access to run that command. This is the info Chimera gives back when it tries to run my code:

/usr/lib/ucsf-chimerax-daily/lib/python3.9/site-packages/setuptools/__init__.py:85: _DeprecatedInstaller: setuptools.installer and fetch_build_eggs are deprecated. Requirements should be satisfied by a PEP 517 installer. If you are using pip, you can try `pip install --use-pep517`. dist.fetch_build_eggs(dist.setup_requires) running install /usr/lib/ucsf-chimerax-daily/lib/python3.9/site-packages/setuptools/command/install.py:34: SetuptoolsDeprecationWarning: setup.py install is deprecated.

The following error occurred while trying to add or remove files in the installation directory:

    [Errno 13] Permission denied: '/usr/lib/ucsf-chimerax-daily/lib/python3.9/site-packages/test-easy-install-134656.write-test'

There is a paragraph of explanation saying maybe I need root access. So, am I at a dead end? Or can you think of a workaround? Thanks for any insight.
