python setup.py egg_info did not run successfully.

I'm a complete beginner in coding, so I'm lost in what to do.
I've been following the readme and during setup, when I write in anaconda prompt, pip install -r requirements.txt,
I get the error:

Collecting sentencepiece==0.1.83
  Using cached sentencepiece-0.1.83.tar.gz (497 kB)
  Preparing metadata (setup.py) ... error
  error: subprocess-exited-with-error

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

Any ideas on what the problem might be, and what to do about it?
Thank you so much!
