Renaming components in the `packages/` directory breaks component imports about langserve HOT 2 OPEN

Hey @Cutwell ! This isn't currently-supported behavior. If you want to switch out the path, there are a few more things to note!

All packages are installed as editable "path" dependencies, so you'll have to re-install the new package (you may want to remove the old one before renaming too).

The from x import chain x is going to be the inner folder within the package (same as all python packages), so you'll need to make sure your x is equal the python path within the inner folder.

app/
packages/
  rag/
    pyproject.toml
    **x/**
      __init__.py
      chain.py

The other option you have is to langchain app add rag-conversation --api-path=rag to "add" the package at a custom path.

Let me know how else I can help!

Hi @efriis , thanks for your response.

I think we can achieve the desired result with existing functionality and some manual steps..

1. Copy the package component to elsewhere in my repository
2. Remove the langserve component with langchain app remove my-app
3. Rename the copied component appropriately
4. Re-add the component from a local sourcepath (langchain app add ...?)
5. Tidy up the copied component and resume development with the newly created / renamed package component

This works up until step 4 - I can create a new LangServe app using a local component as a package using langchain app new my-langserve --package $PWD/my-app, but it's unclear how to do this with an existing langserve project.
