Error installing langgraph from requirements.txt: yanked version and problem with langgraph-sdk

[JeanVittory]

Hi,

I'm using python 3.8.10 with ubuntu 20.04.6 and following your online course about lang-graph.

When I ran:

pip install -r requirements.txt

I received this message:

I solved the problem by updating my Python version. Some dependencies such as lang graph do not work with versions prior to Python 3.9.0.

Maybe if we can get the versions in requirements.txt could be nice.
