Error :

==========================================================================
When I check the venv, I don't see langgraph_prebuilt module in the venv dir - this is also mentioned in pypy.

Description

I am trying to import langgraph.prebuilt to use create_react_agent

I am able to do in langgraph 0.2.76 but not with anything in 0.3.* onwards

I see in pypy for https://pypi.org/project/langgraph/0.3.0/

Reason this release was yanked:

Missing dependency on langgraph-prebuilt

I think this is still not fixed - please look at it.

I have the same problem which langgraph 0.3.11. (python version 3.13 and 3.12 both)

Please reinstall langgraph in a fresh virtualenv. langgraph-prebuilt is now a separate library (bundled w/ langgraph by default). See more here https://github.com/langchain-ai/langgraph/releases/0.3.1
