I've been using octoprint for quite a while now, but I have a problem after updating to 1.3.11. My server is not starting anymore. Manual starting the server returns this error:
pkg_resources.DistributionNotFound: The 'psutil<5.5,>=5.4.6' distribution was not found and is required by OctoPrint
But when updating Octoprint by hand I get no error regarding psutils:
Requirement already satisfied: psutil<5.7,>=5.6.1 in /usr/local/lib/python2.7/dist-packages
Do you have any ideas why it is not working? I love this piece of software and do not want to print without it!
