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!
