i try to install the Plugin Printer Statistic but always get the error:
RuntimeError: Python version >= 3.5 required.
Command "python setup.py egg_info" failed with error code 1 in /tmp/pip-install-TQmvzp/pandas/
if i try to install pip3 i get the message the newest version is already installed.
in the Pluginmanager i see the following:
[Using pip of "/home/pi/oprint/bin/python2", Version 19.0.1](javascript:void(0))
The plugin itself doesn't require Python 3. It does require tinydb and pandas. I'm guessing that one of those dependencies now has moved beyond Python 2 and is complaining.
The good news is that foosel is working on a version of OctoPrint which supports Python 3. The bad news is that your other plugins would also need to be Python 3—compatible and tested with that. I would suggest ignoring the Statistics plugin for a bit.
