prebuilt has been separated into a standalone package after version 0.3.0, but the main package still has a default dependency on it.
If you are using a virtual environment, try removing the entire langgraph and then reinstall it.

langgraph already includes this prebuilt dependency, so usually, there's no need for additional installation.

If you encounter issues with importing, it's recommended to completely uninstall the package and then reinstall it, rather than simply updating it.

For example, first use pip uninstall langgraph and then pip install langgraph, instead of directly using pip install langgraph.

@francis-bm commented on GitHub (May 22, 2025):

I got it to work:

First:
pip uninstall langgraph
Second:
pip uninstall langgraph_prebuilt

Then:

pip install langgraph

It should work now. The problem was that when you uninstall langgraph, it does not uninstall langgraph_prebuilt, so you need to uninstall as well.
