@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.

[sdetweil]

@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?

(alt-spacebar, n to minimize MM screen)

pi@PiMirrorNeu:~/MagicMirror $ npm start

MagicMirror will not quit, but it might be a good idea to check why this happened. Maybe no internet connection?
If you think this really is an issue, please open an issue on GitHub: https://github.com/MichMich/MagicMirror/issues
Launching application.

@Vauxdvihl Error: Cannot find module ‘del’

that will do it

do

cd ~/MagicMirror
npm install del 

[Vauxdvihl]

What is “del”
And why is needed now?
Strange

[sdetweil]

@Vauxdvihl it was needed by MMM-Weatherchart module, but got deleted on the base update.

the automated script cycle was skipped due to the error
(this is the WHOLE reason I created the automated script, to cover this very problem)

what is it? its some npm library the module uses

[Vauxdvihl]

Ok
Thanks
Everythings works fine now
