pip cannot install requirements_all.txt

[janiversen]

The problem

On current dev, pip fails:

ERROR: Cannot install -r requirements_all.txt (line 1003), -r requirements_all.txt (line 1054), -r requirements_all.txt (line 1165), -r requirements_all.txt (line 592), -r requirements_all.txt (line 919) and -r requirements_all.txt (line 949) because these package versions have conflicting dependencies.

The conflict is caused by:
    devolo-home-control-api 0.18.2 depends on websocket-client>=0.58.0
    homematicip 1.0.13 depends on websocket-client>=1.0.0
    ibm-watson 5.2.2 depends on websocket-client==1.1.0
    jellyfin-apiclient-python 1.9.2 depends on websocket-client
    libsoundtouch 0.8.0 depends on websocket-client>=0.40.0
    mycroftapi 2.0 depends on websocket-client==0.44.0

We should really do something to not allow such conflicts. I presume some of this happened as part of a bump library PR.

Would it be possible to have a special CI action for "bump library PR" that tries to do

pip install -r requirements_all.txt
pip install -r requirements_test_all.txt

This is potentially a runtime problem as well.

Home Assistant relies on the legacy resolver, please add the --use-deprecated legacy-resolver flag to your pip commands.

For example:

pip install -r requirements_all.txt -c homeassistant/package_constraints.txt --use-deprecated legacy-resolver --upgrade
