TypeError on import

[didimelli]

I am on WSL2, with python 3.8. I installed tractor via poetry, with the command poetry add git+https://github.com/goodboy/[email protected].

If i try to import the module, i get a ValueError.

❯ poetry run python                           Python 3.8.8 (default, Apr  1 2021, 11:08:44)

TypeError: 'type' object is not subscriptable

Looking at the exception, it seems that my import is failing due to the use of dict as a type (I believe it is sintax of python 3.9).

Looking at the setup.py of Tractor, it seems that python3.8 should be supported https://github.com/goodboy/tractor/blob/master/setup.py#L68.

Is python3.8 being actually unsupported, or is the dict an error?
Unluckily, I am not sure i can use python 3.9 on this project.

@didimelli sorry, i missed this post!

We actually aren't supporting 3.8 any more iirc since #248.

If the setup.py doesn't reflect this (which it seems you are correct it still is showing 3.8 support) it's a bug and please feel free to PR in the change.

Fwiw alpha 2 should support 3.8 if you really are stuck on that version.
I believe we've agreed while still in pre-first major relase we're just sticking with the latest 2 minor Python versions.
