Octoprint server won't start after upgrade to 1.3.10

It would be interesting to see what was in there from earlier when it was producing a zero-byte octoprint file.

It may be too late, it seems like this folder/file no longer exists:

pi@octopi:~ $ sudo ls -la /tmp/pip-ephem-wheel-cache-6GIZcP/wheels/2e/0d/09/39f09d58d37b3c4977631d1a6c08c6c66c893b6c7eac42e3dc

yeah, I suspect 'ephem' is "ephemeral". And reinstalling without force doesn't look for file diffs or anything.

I installed the octprint files for 15.1 cleanly, I then got a pop up for the update, clicked to install and ran into this issue. I tried to run "pip install --force-reinstall https://get.octoprint.org/latest" and could not.

sudo apt-get update
sudo apt-get install python-pip
it appears pip is not installed ? installed pip and testing if the force reinstall fixes it.

installed a nightly 16 version and same thing, pip is not installed ?

On OctoPi:

~/oprint/bin/pip install --force-reinstall https://get.octoprint.org/latest

I tripped over this issue as well. Same symptoms as noted here. Finally fixed by

$ pip install --force-reinstall https://get.octoprint.org/latest

Another point of reference; I have three printers all with Raspberry Pi 3's running Octoprint. Two upgraded without issue (a Prusa MK3 and Printrbot Play with Rambo Mini board). The third manifested the problem described in this thread (a second Printrbot Play with Rambo Mini board, identical to first).

I don't think it will show anything more than previously provided output, but just in case:
