The 'pip' command could not be found or does not correctly work for this installation of OctoPrint

The pip command could not be found or does not work correctly for this installation of OctoPrint - please consult the log file for details and if necessary configure it manually. No installation and uninstallation of plugin packages is possible while pip is unavailable.

i have tried running pip install --upgrade within the venv and it does seem to say that pip is updated and installed, i suspect it's a user permission issue though I'm not 100% familar with linux environments.

running on Debian 9, standard octoprint installation following the raspbian instructions.

I have attached the log below

this seems to be the issue however i don't know how to resolve it.

Have you installed OctoPrint via OctoPi or onto an existing https://discourse.octoprint.org/t/setting-up-octoprint-on-a-raspberry-pi-running-raspbian/2337 installation?

this isn't running on a rpi, it's running on an standard PC, thus running normal debian 9.
followed the standard raspbian installation procedure as raspian is based on debian.

i suspect it's a user permission issue.
though i don't unfortunately know enough to diagnose.

fixed the problem doing a

chown -R on the octoprint folder.

for future reference the python folder was owned by root, thus the normal user couldn't access pip.

...noting of course that Raspbian out-of-the-box has the pi user setup already and Debian does not.

even i was facing the same issue.
open plugin manager
there is a wrench icon on the top right hand side.
click on it
there is a option for pip configuratation
slection forece the use and save

Sorry to resurect an old thread like this, but I had some trouble with my Octoprint and did a clean install. I got the 1,3,12 version and I have the pip error. Problem is, I know very little about coding and don't know hot to do a chown -R as it says. Please help me!
