How to upgrade Langgraph cli

Product Help LangSmith

I run the cmd: ‘langgraph dev’, LangSmith notified me to upgrade the LangGraph CLI:

Current Server Version: 0.2.56

Latest Server Version: 0.2.100

Seeing issues? Try upgrading your server by upgrading the LangGraph CLI.

But my langgraph cli is the latest version:

(react-agent) ➜  langgraph-server git:(f_Lee_250722_new_pq) ✗ langgraph --version
LangGraph CLI, version 0.3.5

How can I upgrade the LangGraph CLI?

The CLI version (0.3.5) and server version (0.2.56) are different components. The warning is about the LangGraph server, not the CLI itself. To upgrade the server version, you need to update the LangGraph package in your project:

pip install --upgrade langgraph

Or if using a specific version:

pip install langgraph>=0.2.100

The CLI version 0.3.5 is likely current, but your project’s LangGraph dependency is still on 0.2.56. Check your requirements.txt or pyproject.toml for the LangGraph version pinning and update it accordingly.

it is about the langgraph server, which is the langgraph-api.

pip install -–upgrade langgraph-api
