(cv) pi@opencv:~ $

Any ideia ?

[digas]

But version : (cv) pi@opencv:~ $ pip install -Iv "picamera[array]"==1.12

Just installed perfectly ...

Facing the same issue installing The Spaghetti Detective plugin in Octoprint on Pi 4 with HQ camera (fresh install).

https://github.com/TheSpaghettiDetective/OctoPrint-TheSpaghettiDetective/issues/66

I managed to solve it by first forcing install of the picamera library before installing the plugin.

sudo -s export READTHEDOCS=True /home/pi/oprint/bin/python2 -m pip install picamera

As this was suggested here : https://github.com/waveform80/picamera/issues/578#issuecomment-523997913

Still there seems to be an issue with the picamera library with HQ camera on Pi 4 as my install is fresh out of the box Octoprint.

Hi,

I've the same issue, so I'm using the version 1.12 but I didn't have this issue before... A mate did an upgrade of my RPI and then... broke.

export READTHEDOCS=True also does the trick.
