Hi Node-red Forums.
I'm working on a RevPI (which is basicalli a Pi, since it's based on its Compute Module) and wanted to use Open-CV-
This is a post on the steps I did, jump to the end for the possible main reason for the fail.
If you have any clues please answer.
If I try to install open-cv from terminal
npm install node-red-contrib-opencv
I have a very huge error that looks like this
npm WARN deprecated hoek@2.16.3: This version is no longer maintained. Please upgrade to the latest version.
npm WARN deprecated boom@2.10.1: This version is no longer maintained. Please upgrade to the latest version.
npm WARN deprecated cryptiles@2.0.5: This version is no longer maintained. Please upgrade to the latest version.

I followed then this tutorial, and followed step 2 (Install OpenCV 4 dependencies on your Raspberry Pi) and 3(Download OpenCV 4 for your Raspberry Pi), while jumped to step 5 (CMake and compile OpenCV 4 for your Raspberry Pi).

Possible reasons for this not to be working: the SD of the revpi (not even an SD) is just 4 Gb.
If I run
pi@RevPi8252:~/opencv-4.0.0/build $ df -h Filesystem Size Used Avail Use% Mounted on /dev/root 3.5G 3.2G 99M 98% / devtmpfs 459M 0 459M 0% /dev tmpfs 464M 0 464M 0% /dev/shm tmpfs 464M 47M 417M 11% /run tmpfs 5.0M 4.0K 5.0M 1% /run/lock tmpfs 464M 0 464M 0% /sys/fs/cgroup /dev/mmcblk0p1 42M 22M 20M 53% /boot tmpfs 93M 0 93M 0% /run/user/1000
While I'll try to replicate the whole experiment on a standard 16Gb Pi3, do you have any suggestions for this to be working with an external memory? any guides or workarounds?
Keep you posted.
