Blank mm after update

evroom

well with the config:check he would not have found the error, would he?

In this case perhaps not, but it cannot hurt to run it in order to exclude error(s) before and after this part of the config.
Normally a 'true' versus true would not cause a black screen, but I might be wrong.
And a trouble shooting guide would have to start with the config:checkIMHO.

u don’t know how the module code might fail…
which is what causes the blackscreen to begin with

Tried the module myself.

seems odd that there would be two invocations of these modules…

but as a test, in MagicMirror/config/config.js add

    disabled: true,

to both those modules, and restart mm and see what happens

sdetweil

missing a required node package ‘del’

no package.json to inform the user

sdetweil

warning, warning… copy and save

MagicMirror/modules/node_modules/node_helper (folder, which contains index.js)

then

cd ~/MagicMirror/modules/mmm-weatherchart
npm install del

check for a missing
MagicMirror/modules/node_modules/node_helper folder
and if so, copy it back

i opened an issue with mmm-weatherchart

I have only one mmm-weatherchart module present.
When disabled everything is fine.
However, I forgot to remove the single quotes, as I just copy/pasted the config from the thread.
Corrected it, but now I get even stronger things.

0|mm  | WARNING! Could not load config file. Starting with default configuration. Error found: Error: Cannot find module 'del'

I do not have any string with ‘del’ in my config :worried_face:

@evroom see my prior most about the missing module

I was typing while you answered.
Will have a look at it and try it out.

The module is running now, but I get this error:

0|mm  | Downloading weather map with signal: FETCH_MAP From URL: www.yr.no/place/Germany/Bavaria/Nuremberg/meteogram.png
0|mm  | Error: ENOENT: no such file or directory, open '/home/pi/MagicMirror/modules/mmm-weatherchart/cache/map-1567097174409.png'

Then I read somewhere there is a clone of this module that is more recent, so I tried that:

https://github.com/szech/mmm-weatherchart

Same result: module runs but no file in the cache dir.
When opening the URL in the browser, it does show the picture that I do not see on my screen.

Oh boy/girl, thought it was a simple syntax thingy in config.js …
