I am working through Master Bitcoin. I got the bitcoin client up and running. I am now trying to access the client from python. In the example, there is a line that says from bitcoin.rpc import Rawproxy.
I get the error message no module named rpc. When I run pip freeze, I have python-bitcoinrpc==1.0 listed. Why can't this module be found?
in debian =)
sudo apt-get install libssl-dev
pip install python-bitcoinlib or pip3 install python-bitcoinlib
import and what you install. I looked everywhere online trying to figure out the library.

bicoinlib is the module you try to use to handle bitcoind, bitcoin-cli in python, rpc module is part of bitcoinlib.
libssl-dev is needed to handle SSL and TLS cryptographic protocols .
if bitcoinlib not work in newer bitcoin core versions 0.15 or newer just use raw bitcoinrpc.authProxy module.
First, install libssl-dev:
sudo apt-get install libssl-dev
Install python3-pip if not yet:
sudo apt install python3-pip
Lastly, install python-bitcoinlib:
pip3 install python-bitcoinlib
In the example code, it is
info = p.getinfo()
Ran the example, I got "bitcoin.rpc.JSONRPCError: {'code': -32601, 'message': 'Method not found'}"
Change it to:
info = p.getblockchaininfo()
(see https://bitcoincore.org/en/doc/0.21.0/rpc/blockchain/getblockchaininfo/)
It works fine. I got the total number of blocks. In my case, it is 682903.
