Component error: pyscript - No module named 'packaging'

[dapuzz]

Hi
Can you help me fixind this issue?
I have upgraded via HACS from 0,xx to 1.0.0 but now I am stuck with this log.

Running HA in virtual env python_version 3.7.3

Thanks

I reverted back to 0,32 and everything is working fine.

@raman325 I believe this is related to your requirements PR.

The "packaging" module seems to be already installed for me, so I don't have this issue. I run the latest version of HA in docker. However, it's not specified in pyscript's manifest.json so it won't be installed if it isn't already. Should it be added there?

[raman325]

hmm @dapuzz what version of Home Assistant are you running? The latest version of Home Assistant requires Python 3.8 at a minimum. Home Assistant uses the packaging module internally but I can't find any references to installing it within the HA code so I assumed it was expected to always be there. I can build a fix for this, I just want to make sure that it is needed before getting too far into it.

I stand corrected, latest can work on Python 3.7

[raman325]

OK I stand corrected again, HA development uses packaging but the actual application does not. Will submit a fix soon.

I reported using 0.115 but now I am running ha 0.117.
The point is that “packaging” is a prerequisite when using pip, so I think pyscript is not using my venv for some reason, but some other python installation on my rpi

[raman325]

pyscript uses HA's installation function for installing packages, so it would be installing packages using the same pip that HA is. I don't think pip needs packaging because I just created a new virtual environment and it wasn't there. Regardless, can you try cloning the following repo and moving the custom_components/pyscript folder into your HA custom_components folder? I can't write a test for this so just want to see if it resolves your issue (it installs packaging on demand)

I confirm this solution works. I was able to grab the installation process and everything has gone ok.
/srv/homeassistant/bin/python3 -m pip install --quiet packaging --upgrade --constraint /srv/homeassistant/lib/python3.7/site-packages/homeassistant/package_constraints.txt

Thanks again, you can merge and close this issue
Bye

Thanks for confirming @dapuzz
