Running a very basic vapoursynth script (no external dependencies beyond basic Vapoursynth, just loads a file and directly outputs) with no other vapoursynth packages fails with "Failed to initialize VapourSynth environment". R46-1 works. (This also occurs with all my standard vapoursynth plugins I use installed, but I uninstalled all of them to make sure it wasn't related to them.)

Additional info:
* vapoursynth-R47-1

Script to produce error (save as test.vpy):
import vapoursynth as vs
core = vs.get_core()
filename = globals()["file"]

clip = core.ffms2.Source(filename)
Command (need input file, here using "test.mkv"): vspipe -p -y -a file=test.mkv test.vpy - | mpv -

This task depends upon
