Where's the repo for langgraph-cli?

[igormp]

I noticed that langgraph-cli is a package that's used in some of the examples in the project, and had some errors related to some package versions inside of it (seems like it tries to build/spin up some containers), however I could not find any repo that seems to have its source code, not the most appropriate place to report such errors.

The package at pypi doesn't point to any upstream project.

Any ideas where I can find the repo for this specific component?

@igormp the CLI will be added to this repo soon, in the meantime I can confirm the errors related to versions are something you need to fix in your code. The errors are there to alert you your project requires versions of dependencies that would conflict with ours. I'd recommend you read through the error and update your dependencies accordingly. If you need help post here the error output and we can help you figure out which ones to update

[nfcampos]

Your project is called chat langchain, or has a dependency called chat langchain?

[nfcampos]

From the logs looks like chat langchain is a dependency, so the version mismatch would have to be fixed there

[nfcampos]

Not sure exactly how you installed chat-langchain in your project but the latest version in the repo seems to have a version range that would work

[igormp]

It's a project that I was building off based on the actual chat-langchain, so yeah, the project itself is chat-langchain haha

Seems like the version in my pyproject.toml conflict with the versions defined in said constraints.txt file. Here's my full file:

And the current error after trying to satisfy most of those constraints:

sse-starlette wasn't even an actual first party dependency I had, I tried to add it to adjust the version but it still errors our nevertheless.

CLI should all be in this monorepo now!
