3 years ago Thanks for reporting the issue @hustlmh . After a quick search, I found that adding from __future__ import annotations might help as a workaround. I didn't test it yet. A dirtier but 100% working fix is to just remove type annotations from line 32:
@contextmanager
def session(self) -> Callable[..., AbstractContextManager[Session]]:I'll also try to see how to make it work on all supported Python versions. Thanks again.

hi, I cloned the git-master code and try to run the example without any modification in my miniconda environment where python version is 3.8.11, but the example “fastapi-sqlalchemy” cannot be executed. The error message is "TypeError: 'ABCMeta' object is not subscriptable". related environment is uvicorn 0.15.0 fastapi 0.68.1 dependency-injector 4.36.0
how to fix it ? Thanks !
fastapi-sqlalchemy % python -m webapp.application
