Because Python's entire ecosystem is such garbage, this can happen if you use another unrelated program somewhere else in your system that depends on ffmpeg.

You can fix this by uninstalling everything related and trying again.

pip uninstall ffmpeg
pip uninstall ffmpeg-python
pip uninstall python-ffmpeg

pip install ffmpeg-python
