MM Ver.2.21 Electron failed to install error

[Rags]

I just updated to ver 2.21. MM crashed and no longer working. npm start shows error

magicmirror@2.21.0 start
DISPLAY=“${DISPLAY:=:0}” ./node_modules/.bin/electron js/electron.js

/home/pi/MagicMirror/node_modules/electron/index.js:17
throw new Error(‘Electron failed to install correctly, please delete node_modules/electron and try installing again’);
^

Please help in resolving issue. A step by step instructions would help. I dont want to reinstall MM all over again. Adding all modules and reconfiguring the config.js file is not an option.
Thanks.

@Rags how did u update? manual git pull/npm install or my upgrade script?

can you show output of

uname -a
lsb_release -a
node -v
npm -v

u ‘might’ have luck with

cd ~/MagicMirror
npm install electron@19.1.0

report the results.

@Rags also if you use something like my backup/restore it could save you literally DAYS of work

see
https://github.com/sdetweil/MagicMirror-backup-restore

and my script repo, install/upgrade

I did a git pull in MM directory.
However before that i had tried to install MMM-json-feed which failed during installation. I guess it must have messed up the electron somhow.
uname -a
Linux raspberrypi 5.10.103-v7+ #1529 SMP Tue Mar 8 12:21:37 GMT 2022 armv7l GNU/Linux
npm -v 9.1.2
node -v 16.8.1
when i do a npm install electron@19.1.0 i get
pi@raspberrypi:~/MagicMirror $ npm install electron@19.1.0

@Rags ok best to clean

do

cd ~/MagicMirror
rm -rf node_modules
rm package-lock.json
npm install --omit=dev  --no-audit --no-fund

@sdetweil
Bingo. All systems go…
Thanks once again.
I am doing the backup restore thing now.
