Has anyone had experience getting

mypy

working in

pants check ::

with

SQLAlchemy

? I have the following in my

mypy.ini

[mypy]
plugins = sqlalchemy.ext.mypy.plugin

I’ve added the following to my

pants.toml

(I’ve tried with/without the stubs package)

[mypy]
extra_requirements.add = ['SQLAlchemy<2.0.0,>=1.4.27', 'sqlalchemy-stubs']
lockfile = "3rdparty/mypy_lockfile.txt"

(this seems to be required because without which I get an error

error: Error importing plugin "sqlalchemy.ext.mypy.plugin": No module named 'sqlalchemy'

) I’ve also tried:

extra_type_stubs = ['SQLAlchemy<2.0.0,>=1.4.27', 'sqlalchemy-stubs']
extra_type_stubs_lockfile = "3rdparty/extra_type_stubs.txt"

But running this still gives me the following error

➜  example git:(pants-migration) ✗ ./pants check services/.../authorise.py
services/.../authorise.py: error: Skipping analyzing "sqlalchemy.orm.attributes": module is installed, but missing library stubs or py.typed marker

EDIT: okay so I’ve fixed it, it looks like the combination of settings I needed appear to be both

extra_requirements

and

extra_type_stubs

[mypy]
extra_requirements.add = ['SQLAlchemy<2.0.0,>=1.4.27']
lockfile = "3rdparty/mypy_lockfile.txt"
extra_type_stubs = ['sqlalchemy2-stubs']
extra_type_stubs_lockfile = "3rdparty/extra_type_stubs.txt"
