@Vauxdvihl try keyboard on mirror, ctrl-shift-i to open dev window

[lavolp3]

@Vauxdvihl or, from your laptop or pc, you can ssh into the mirror, got to the MagicMirror directory and execute the following for dev mode:

pm2 stop all
npm start dev

See if there are errors coming up in the console.

Is there still no troubleshooting guide around to reference to?

[Vauxdvihl]

npm start dev

results in

pi@PiMirrorNeu:~ $ npm start dev
npm ERR! code ENOENT
npm ERR! syscall open

@Vauxdvihl from the magicmirror folder

all commands suggested are always from the magic mirror folder

[Vauxdvihl]

Ah ok
Sorry

DevTools was disconnected from the page.
Once the page is reloaded, DevTools will automatically reconnect.

@Vauxdvihl this is still MagicMirror version 2.9?

a guess

do

cd ~/MagicMirror
git checkout modules/node_modules/node_helper/index.js

[Vauxdvihl]

@sdetweil
Where do i see it?

Nothing happen:

pi@PiMirrorNeu:~/MagicMirror $ git checkout modules/node_modules/node_helper/index.js
pi@PiMirrorNeu:~/MagicMirror $ 

[sdetweil]

@Vauxdvihl
and then restart mirror

[Vauxdvihl]

@sdetweil
Mirror stays black :-(

[sdetweil]

@Vauxdvihl if you do

cd ~/MagicMirror
npm start

what do you see on the terminal window?
