Tried direct python method, and docker method, just using roo code to do the setup, running on linux mint. Not sure what has gone wrong.
ERROR: Could not find a version that satisfies the requirement langgraph-api==0.0.22 (from versions: none)
ERROR: No matching distribution found for langgraph-api==0.0.22
Update: You can remove the langgraph-api from the requirements.txt file. Then it works. Just tested it. @ColeMedin will remove this in the repo as well then.
It´s most likely a problem with the python version. In my case 3.13. Think yours too @jez ?
