[Selur]

I'm trying to install vs-denoise in a portable Vapoursynth R65 version using: python -m pip install git+https://github.com/Jaded-Encoding-Thaumaturgy/vs-denoise.git and get:

      [end of output]

  note: This error originates from a subprocess, and is likely not a problem with pip.
error: metadata-generation-failed

× Encountered error while generating package metadata.
╰─> See above for output.

note: This is an issue with the package mentioned above, not pip.
hint: See above for details.

Site note: It works fine with R66, but there the portable package was reworked and a VapoursynthR66 wheel file was installed. (So it's a problem with portable Vapoursynth before R66.

=> Is there some environment variable I can set so that this does not happen with R65?

Has nothing to do with the package, open a relevant issue in the vapoursynth repo.
