Package is missing library stubs or py.typed marker

[amotl]

Problem

When deriving a CrateDB adapter for LangChain from langchain-postgres, we are observing this error when invoking make lint.

langchain_cratedb/cratedb/model.py:16: error: Skipping analyzing "sqlalchemy_cratedb": module is installed, but missing library stubs or py.typed marker  [import-untyped]

Workaround

For your pyproject.toml.

[tool.mypy]
ignore_missing_imports = "True"
