Problem with instalation on raspbian

[Ety60]

Hello everyone,
I used the Magic Mirror website installation guide, but I got the error that my node.js version is not supported by Magic Mirror (it was the node.js version that was on the website: version 10. I don’t now). So I installed the latest version of node.js (version 12.18.2) with this command:

curl -sL https://deb.nodesource.com/setup_12.x | sudo -E bash -

But then I got this error:

> magicmirror@2.12.0 start /home/pi/MagicMirror
> DISPLAY="${DISPLAY:=:0}" ./node_modules/.bin/electron js/electron.js
sh: 1: ./node_modules/.bin/electron: not found
npm ERR! code ELIFECYCLE

npm ERR! spawn ENOENT
npm ERR! 
npm ERR! Failed at the magicmirror@2.12.0 start script.
npm ERR! This is probably not a problem with npm. There is likely additional logging output above.
npm ERR! A complete log of this run can be found in:

Can anyone help me?

@Ety60 use the install script command from here

https://github.com/sdetweil/MagicMirror_scripts

if this is a pi0, electron is no longer available, but I set the system up in split mode the run chromium instead

[Ety60]

I did it and it was successful. But what do I do now to restart the MagicMirror software? It still doesn’t work with this:

cd MagicMirror

npm run start

I’m using an rpi 4 for this project.

@Ety60 when u did the install, did u say yes to pm2?

if so, then pm2 start 0 should work, also npm start should work

if you did use pm2, then it will start at boot, so npm start would try to start a second copy.

pm2 status will show u what is running

[Ety60]

The program did not ask me to install pm2.

[sdetweil]

@Ety60 then u did not use my script.
does ~/install.log exist?

[Ety60]

yes ~·install.log exist. So I think I used your script.

[sdetweil]

@Ety60 and it should have prompted you, “Do you want to use pm2 to autostart your MagicMirror”

if u said n, and want to fix it, you can use the fixuppm2.sh script

[Ety60]

@sdetweil I tried to run the entire script again and this time asked me for pm2. It worked and MagicMirror now works. Thank you very much for your help!
