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`npm WARN deprecated hoek@2.16.3: This version is no longer maintained.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`npm WARN deprecated boom@2.10.1: This version is no longer maintained.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`npm WARN deprecated cryptiles@2.0.5: This version is no longer maintained.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](https://www.pyimagesearch.com/2018/09/26/install-opencv-4-on-your-raspberry-pi/), 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](https://revolution.kunbus.de/forum/viewtopic.php?t=865)) 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.

If you are installing a node-red node using the command line you need to be in you .node-red directory to do it.

\> opencv@6.0.0 install /home/pi/node\_modules/opencv

suggests you weren’t

thanks will test
