ModuleNotFoundError upon installation

[lennijusten]

When installing pylabrobot==0.1.6 and running

from pylabrobot.liquid_handling import LiquidHandler

I get an error:

[rickwierenga]

is this installing from PyPI? The PyPI version is (very) outdated, please install from source instead

[rickwierenga]

actually, also an error on plr:main. will fix now

[rickwierenga]

https://github.com/PyLabRobot/pylabrobot/commit/08a36664fdbac871336d5b2ada2952678af0ce2b should fix it

[lennijusten]

Yup, thanks. I'm using a version cloned from source.

[rickwierenga]
