ImportError: cannot import name 'RPCResponse' from 'solana.rpc.types'

[Broever101]

While running the example code:

from pyserum.connection import get_live_markets, get_token_mints
print("tokens: ")
print(get_token_mints())
print("markets: ")
print(get_live_markets())

The error:

Checking out the latest solana.rpc.types, there really is no RPCResponse.

Any pointers/fixes?

Seems to fix that error but this:

I have my own fork now, I plan to add support for other DEXes.
https://github.com/pbharrin/py_no_broker

There is example code here, showing the current orderbook for Openbook:
https://github.com/pbharrin/py_no_broker/blob/alpha/examples/show_orderbook.py

All you should need is to install solana and requests.
pip install solana
pip install requests

Great! I'll try it.

Btw, in the past hours I made some of the branches of this repo work (those failing because of missing RPCResponse) by hardcoding the solana version to this:

solana==0.20.0

maybe this may help someone.... and.. as because this is actually what this ticket was about...

@Broever101 yes, setup for example solana dependency to version 0.20.0 :

• One way: you can try, after installing dependencies to uninstall solana package (pip uninstall solana) and then install again but fixing the version to 0.20.0 (with: pip install solana==0.20.0 )
• Other way could be before installing everything setup requirements.txt to have solana using the mentioned version and proceed to install.

That worked for me.

Yes, actually I got it to work a long time ago by using the hardcoded version. Forgot to update here, but thanks for the update! It'll be helpful to anyone coming along later.
