Cannot install v0.40 because of dependency solution failure #19

Closed hongquan closed 7 months ago

hongquan commented 7 months ago

The versions of moat-mqtt and anyio dependencies don't match.

lulingar commented 7 months ago

I also saw that. It looks to me like the issue is caused by moat-util:

$ pip install moat-mqtt==0.40.1
...
ERROR: Cannot install moat-mqtt and moat-mqtt==0.40.1 because these package versions have conflicting dependencies.

The conflict is caused by:
    moat-mqtt 0.40.1 depends on anyio~=4.0
    asyncscope 0.6.0 depends on anyio>=3
    asyncwebsockets 0.9.3 depends on anyio>=3.0
    moat-util 0.35.0 depends on anyio~=3.0

To fix this you could try to:
1. loosen the range of package versions you've specified
2. remove package versions to allow pip attempt to solve the dependency conflict

@lulingar These dependencies should not block updating anyio to 4.2 AFAICT.

moat-util isn't the culprit, it is at version 0.43.2 and requires anyio >= 4.2.

Please try updating anyio and moat-util manually, and file a bug to the package that prevents this.

I'm closing this issue because it's not a problem with moat-mqtt.

NB, I have updated asyncscope. It now also depends on anyio 4.

Surely this could be worked around by manually updating the dependencies to the more recent versions, however the issue is that it isn't working on a clean virtualenv, i.e. "out of the box", which is what the log excerpt I posted shows. As you can see, moat-util seems to be pinned at 0.35.0.

smurfix commented 7 months ago

The question is, where does the pin come from? I'm 99% sure that some interaction between dependencies does the pinning, which is why I asked for trying to manually upgrade these packages, which should result in a more descriptive error message.

Hi @smurfix, please forgive my forgetting to get back to you. I have attempted the upgrades as you suggested, but the result is the same. I'm attaching the terminal scrollback dump for you to see all of the details. attempt-with-upgrade.log

Thanks for the log. moat-mqtt 0.40.2 pushed.
