setup.py doesn't accept the --root=/stage/dir argument

[yurivict]

Most python projects specify the stage directory through --root=/stage/dir argument. But setup.py from pyne fails:

  import imp
usage: setup.py [-h] [--clean [CLEAN]] [--user [USER]] [--egg-base EGG_BASE] [-D VAR] [--build-type BT] [--deps-root DEPS_ROOT] [--fast] [--slow] [-j J] [--hdf5 HDF5] [--moab [MOAB]]
                [--dagmc [DAGMC]] [--prefix PREFIX] [--build-dir BUILD_DIR] [--bootstrap] [--spatial_solvers] [--no_spatial_solvers]
                cmd
setup.py: error: unrecognized arguments: --root=/usr/ports/science/py-PyNE/work-py38/stage

How to install pyne into a stage directory then?

Version: 0.7.5
Python: 3.8

I'm not sure what you mean by a 'stage directory'. Do you want to install and use this from some custom location? Or do you want to temporarily install in a custom location and then move from that location to a final location?

[yurivict]

Stage directory is where it is installed temporarily and then it is moved to ${PREFIX}.

So every package should be able to install itself into ${STAGEDIR}${PREFIX} as if it is installed into ${PREFIX}.

For this the install target has to accept 2 separate arguments: STAGEDIR and PREFIX. In Python projects this is usually achieved by supplying --root=${STAGEDIR}.

The current setup.py does not include the --root argument. I believe you should opt for the --build-dir instead. Our setup.py has been custom developed.
