bw2io.bw2setup() error on osx-arm64

[Phurga]

Hello,

I am trying to run the ecoinvent import example from brightway documentation on my m2 mac (https://docs.brightway.dev/en/latest/content/examples/brightway-examples/data_import/ecoinvent_import.html)

I am using this library: brightway25_nosolver version 1.0.6 build py_4 (following the installation instructions)

Calling bw2io.bw2setup() raises the following error:

_"AttributeError: 'Config' object has no attribute 'istest'" (full error code is attached below)

It looks like the Config class indeed does not have

I have tested with previous builds and still have errors, I have done a clean reinstall of my environments (including conda resinstalls through mambaforge since anaconda did not work out)

Many thanks in advance! Adrien

Below the full error code:

Sorry about this, I prematurely merged code incorporating https://github.com/brightway-lca/bw_projects, but this was premature. Please install bw2data 4.0.dev29 from the conda channel cmutel or from pypi, this should fix things.

Excellent, I now have a working environment!! Many thanks @cmutel :)
