import error

[BeatScherrer]

I'm trying to use your package instead of writing my own parser and got stuck on importing the package:
I installed the package in a virtualenv:
I'm running Python 3.9.1

when trying to import it according to your example:

#!/usr/bin/python

import os
import xrp


def main():
  print('test')


if __name__ == "__main__":
  main()

i get the following error:

Traceback (most recent call last):
  File "/home/beat/git/beat/gravel-pit/scripts/./test.py", line 4, in <module>
    import xrp
ModuleNotFoundError: No module named 'xrp'

the output of pip show xparser:
