Problem with conda installation : failed with initial frozen solve

Hi, I have installed cadquery successfully with:

conda install -c conda-forge -c cadquery cadquery=2

I am trying now to install CQ-editor as explained here. It fails with this messages (extract, cuts = […], full here part 1, part 2):

(base) lalebarde@PC:/opt/openscad$ conda install -c cadquery -c conda-forge cq-editor

I have also tried the solution here, but without success:

(base) lalebarde@PC:/opt/openscad$ conda env create -f cqgui_env.yml -n cqgui
SpecNotFound: Invalid name, try the format: user/package

I am not a conda user, so I don’t know if the installation sequence for cadquery, then CQ-editor is correct ?

@lalebarde The conda line above assumes that you pulled the latest master.

@lalebarde I think it’s because I forgot to update the version number in CadQuery’s init.py and so CQ-editor thinks it’s not updated.

If you’re running Anaconda you should be able to do the following, but the update message will persist. You should have the latest version though.

conda env update -f cqgui_env.yml
