Error when starting the mirror with MMM-Face-Reco-DNN installed

[NightFalcon650]

Goodevening,

I've installed the Face-Reco module but when i start with NPM start i'm getting this error: [21.01.2023 18:46.41.362] [LOG] [MMM-Face-Reco-DNN] loading encodings + face detector... [21.01.2023 18:46.41.450] [LOG] [MMM-Face-Reco-DNN] starting video stream... [21.01.2023 18:46.41.792] [ERROR] Whoops! There was an uncaught exception...

What's going wrong and how can i get it to work?

hi @NightFalcon650 It look like you did not installed the dependencies of my module. Did you run npm ci or npm install for my module?

Thanks for the quick reaction.

yes i tried this a couple of times but that produces errors: ` magicmirror@raspberrypi:~/MagicMirror/modules/MMM-Face-Reco-DNN $ npm install npm ERR! code ERESOLVE npm ERR!

I tried it with the --force but still no luck I'm a little bit stuck and don't know what to do now??

[nischi]

hmm this is a little strange. did you tried npm ci instead of install?

[nischi]

can you give me the version of node and npm do you have?

npm --version
node --version

[NightFalcon650]

The versions are: magicmirror@raspberrypi:~/MagicMirror/modules/MMM-Face-Reco-DNN $ npm --version && node --version 9.2.0 v16.19.0

[nischi]

Maybe this is the problem, can you update to the latest node lts version. this should be 18.13. Not sure if this solve the problem, but could be.

i've updated to 18 and tried it - no luck After this i tried 19 and also - no luck Uninstalled NodeJS and reinstalled version 18 again - no luck

Very strange :-S

This is very strange. i tried it, works fine without any issues.

Can you try to avoid the dev dependencies, because you do not really ned them. npm install --omit=dev

Or can you try to manualy update the dev dependencies in package.json to the most actual ones?

  "devDependencies": {
    "eslint": "^8.32.0",
    "eslint-plugin-import": "^2.27.5",
    "eslint-plugin-node": "^11.1.0",
    "eslint-plugin-promise": "^6.1.1",
    "eslint-plugin-standard": "^5.0.0"
  }

you can remove the eslint-config-standard

Took me a couple of days of spare time while working and searching the internet but i tried both but without luck. Still giving errors.

After this i removed MM completly, did a reinstall - no luck

At the end i've done a complete new install on a other SD-card and have the same issues. Searching further on the internet revealed that the MMAL libaries aren't supported on the newest PI4 OS. https://askubuntu.com/questions/1434193/install-rpi-userland-on-arm64-pi-4-running-ubuntu-pi-22-04-server My cam works but not with the MMM-module. Still looking to get it working but don't know how. I'd like to help you in making, and testing it to get this great module to work.

[nischi]

but for my point of view this has nothing to do with the os. but we never know.

so you removed the eslint dependencies completly from the package json and did a npm install and got the same error?
