minor compatibility issue

[taneugene]

In bw2io/importers/ecoinvent_lcia.py, lines 18-24.

class EcoinventLCIAImporter(LCIAImporter):
    def __init__(self, biosphere_database: str | None = None):

The | None = None format isn't compatible with Python versions <3.10, and brightway is supposed to be compatible with python versions >= 3.8.

Is there a way to fix this, perhaps just by taking it out?

Hi, I have the same problem. I tried with python 3.9.13 and with python 3.12.3. Any ideas for fixes, yet?

Are you using brightway2 or brightway25?

according to the changelog this is already solved in version 0.9.DEV29
