updating AB breaks AB

[marc-vdm]

Updating AB by conda update -n ab --channel conda-forge activity-browser (copy pasted from instructions) broke my (non-dev) AB environment. It could be an issue with BW?

Updating AB_dev by

conda activate ab_dev
conda update --channel conda-forge activity-browser-dev

(copy pasted from instructions) broke my dev AB environment. Same issue as original post?

This seems to be an issue regarding the upgrade to python 3.8. I've reverted the version updates back and will do more testing on the dev branch on Github. These changes will take about an hour to update on conda. So we'll test it soon

[StpdFox]

Have you tried installing the release version? instead of the dev? Did you get the same result?

Have you tried installing the release version? instead of the dev? Did you get the same result?

Yes. Same result when installing the release version in a new environment. Two minutes ago, the next command:

conda create -y -n ab -c conda-forge -c cmutel -c bsteubing -c haasad -c pascallesage "activity-browser>2.4"

installs activity-browser, version 2.6.3, build pypy_0, channel bsteubing.

When trying to launch the activity-browser, the same error message ending with

OSError: [WinError 126] The specified module could not be found

appears

[StpdFox]

The issue relates to a bug in brightway They are working on it, i'm trying to chip in but it did mess up conda.

[StpdFox]

There's a workaround. You have to create a new enviroment with this command : conda create -n <Your Environment Name> -c conda-forge -c cmutel -c bsteubing -c haasad -c pascallesage "activity-browser>2.4" mkl=2020.2 python=3.8

Then activate that environment by typing conda activate <Your Environment Name>

and run the AB by typing activity-browser

i hope this works for you.
