I can not install a forked version of Qcodes with test dependencies:

Hi @FredWolff I add your question here, since I suspect other people could have the same issue :

Problem, I can not install a forked version of Qcodes with test dependencies:

>pip install -e .[test] -c requirements.txt
ERROR: Cannot install qcodes, qcodes[test]==0.0 and zhinst-qcodes==0.5.2 because these package versions have conflicting dependencies.

root cause; the fork do not have any tags:

>git describe --tags
fatal: No names found, cannot describe anything.

solution fetch tags from upstream:

>git remote add upstream https://github.com/QCoDeS/Qcodes.git
>git fetch --tags upstream

confirm it works:

>git describe --tags
v0.39.0-166-g99d9b267b
>pip install -e .[test] -c requirements.txt
Successfully installed qcodes-0.40.0.dev166+master.g99d9b267b
