I get this error message when I try to import bw2data in a fresh conda environment with python 3.9 The environment was created by: conda create -n my_new_bw_env -c conda-forge -c cmutel brightway25 python=3.9

The documentation says, python 3.9 is supported.

Hi @HaSchneider . This happens with the current version published on conda channels (cmutel) . The latest bw2data packages are not uploaded. The simple solution is to conda install fs

An alternative would be to install using pypi (because teh packages on pypi.org are more up to date), but I suggest to stick to one or the other, and not mix them [although recently this is not so much of a problem]

We shifted from pyfilesystem2 which is effectively abandonware to fsspec which has an active development community in June. Sorry if the dependencies weren't pushed to the conda recipes correctly, this should be fixed now.
