Summary

Fresh ra-aid setup fails at startup with the following error

$ ra-aid
Traceback (most recent call last):
  File "/home/rojovel/redjar/i+d/RA.Aid/venv/bin/ra-aid", line 5, in <module>
    from ra_aid.__main__ import main

    from langgraph.graph.graph import CompiledGraph
ModuleNotFoundError: No module named 'langgraph.graph.graph'

I tried to force install the version of langgraph in the pyproject.toml file but then I get tho following error
"""
from google.longrunning import (
File "/home/rojovel/redjar/i+d/r4r/raaid/path/to/venv/lib/python3.12/site-packages/google/longrunning/operations_proto_pb2.py", line 40, in
DESCRIPTOR = _descriptor_pool.Default().AddSerializedFile(
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
TypeError: Couldn't build proto file into descriptor pool: duplicate file name google/longrunning/operations.proto

This makes me think that probably some update in the dependencies from google could create a dependency mismatch.

Environment

Component	Version
OS	Alpine 3.21 (Docker)
Python	3.12.3
ra-aid	0.30.2

Steps to Reproduce

1. Fresh virtual-env / container
2. pip install ra-aid

Same problem here when working in Arch, using both uv installation (in python 3.12), as well as standard virtual environments using python 3.13.

same error with ubuntu using pipx install ra-aid

Downgrading to langgraph==0.4.10 resolved the issue for me. This created a ReAct Agent error for a method call that was providing input_schema but the method did not have that defined. I simply removed passing that variable to the method and all is working.

Had the same issue on macOS when installing with

uv tool install ra-aid

As per previous comment tried downgrading using:

uv tool upgrade ra-aid --upgrade-package langgraph==0.4.10

Started getting the following error afterwards:

.../.local/share/uv/tools/ra-aid/lib/python3.12/site-packages/langgraph/prebuilt/chat_agent_executor.py", line 39, in
from langgraph._internal._runnable import RunnableCallable, RunnableLike
ModuleNotFoundError: No module named 'langgraph._internal'

happened to me too, but I was using pip. same langgraph internals error

[jovelromeo]

This error could probably show up because of langgraph and google dependencies changing their dependencies.
Using uv sync (wich uses uv.lock) fix this problem when building from source.

I have this running with the following initial setup:

git clone --branch v0.30.2 https://github.com/ai-christianson/RA.Aid
cd ./RA.Aid
uv venv -p 3.12.11 && uv sync && install .venv/bin/ra-aid /usr/bin

A dependency definition update is probably needed. Maybe it could be possible to make a dependency definition that sticks to the working uv.lock and then move forward with the dependencies update.

I have this running with the following initial setup:

git clone --branch v0.30.2 https://github.com/ai-christianson/RA.Aid
cd ./RA.Aid
uv venv -p 3.12.11 && uv sync && install .venv/bin/ra-aid /usr/bin

I confirm that it worked, but I have to manually install ripgrep because it complains about that missing dependency.

$ ra-aid

For me worked this:

pip install \
  langgraph==0.4.10 \
  langgraph-prebuilt==0.2.0 \
  langgraph-checkpoint==2.0.26 \
  langgraph-sdk==0.1.59 \

  langchain-ollama==0.3.0 \
  langchain-google-genai==2.1.1 \
  langchain-fireworks==0.2.8 \
  langchain-groq==0.3.1

Then install ra.aid from source.
