blockchain – bitcoin-etl: issues with putting in

I’m making an attempt to put in bitcoin-etl: https://github.com/blockchain-etl/bitcoin-etl to investigate bitcoin blockchain.
I’ve Mac OS and python3, I run this in terminal:
pip set up bitcoin-etl
Additionally tried this:
python3 -m pip set up bitcoin-etl
The output is:ERROR: Couldn't discover a model that satisfies the requirement bitcoin-etl
ERROR: No matching distribution discovered for bitcoin-etl
I’ve python3 and pip put in:python3 -m pip --version
pip 21.0.1 from /Library/Frameworks/Python.framework/Variations/3.8/lib/python3.8/site-packages/pip (python 3.8)
Any strategies?
Thanks!!!
P.S. BTW, if another methods to investigate bitcoin blockchain (I want csv for block counts vs time) your recommendation would even be very considerable!
