Possible Python install error: 2025.2

[cjp767]

On startup after installing the new 2025.2, I had a problem with my MQTT Broker plugin. I initially thought there was a possibility that the plugin needed to be updated as was mentioned in the 2025.2 release notes. I checked with the plugin author (on the MQTT thread) and he said my log indicates something is broken in my Python install. pkg_resources is a standard Python library that should be installed by the Python installer. I went back to 2025.1 and everything is running smoothly. Thank you for any guidance.

Here's a copy of my log:

Sadly, it looks like pkg_resources was deprecated in Python 3.13, and at least in some cases (we have multiple installs, some have it others don't) it was actually removed.

So, not a corrupt install but rather a deprecated library in Python 3.13.

Thank you for that info. But what do I do with it? Is this then a plugin issue? Should the plugin be written not to use or access that deprecated file? or should I recreate that library (somehow) manually?

Yes, it's a plugin issue.

Plugin has been fixed.
