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 …

the module doesn’t work, but doesn’t kill MagicMirror anymore…

Correct.

I have a few questions.

In the original module there is no package.json file, where in the cloned one there is.
So, when using the original module, you should NOT use npm install, right ?
First of all it will no do anything useful, but it WILL delete your /home/pi/MagicMirror/modules/node_modules/node_helperdirectory and its index.js file.
When using the cloned module, you should run npm installin order to install the dependencies mentioned in it, right ?
No harm is done to the node_helper dir.

Or is it all BS I am telling here (and made the wrong observations) ??

sdetweil

@evroom i cloned and got no package.json
i cloned this
https://github.com/paphko/mmm-weatherchart

sdetweil

@evroom yes, to all your observations…

evroom

When I use
$ git clone https://github.com/szech/mmm-weatherchart.git
then it works.
The README.md from szech point to papkto.
When corrected and doing npm install in the mmm-weatherchart directory, it works

sdetweil

@evroom yes, that module has it…

@sdetweil Thanks! This worked for me as it doesn’t kill it anymore. Hope for a quick fix. Can I follow the process somewhere?

Hi @kvicksson ,

To me it seems there are 3 problems here.
You could have a look what the pm2 log says:

$ pm2 logs --lines 100

You will either have:

Error: Cannot find module 'del'

or:

Error: ENOENT: no such file or directory, open '/home/pi/MagicMirror/modules/mmm-weatherchart/cache/map-1567097174409.

or something completely different.

The 3 problems and potential solutions:

You’re config.js entries:

updateInterval: '3600000',
hideBorder: 'true'

should be:

updateInterval: 3600000,
hideBorder: true

even if the module could potentially handle it.

If your mmm-weatherchart instal has this file present:

/home/pi/MagicMirror/modules/mmm-weatherchart/package.json

then you should run:

$ cd /home/pi/MagicMirror/modules/mmm-weatherchart/
$ npm install

If your mmm-weatherchart instal has this file NOT present:

/home/pi/MagicMirror/modules/mmm-weatherchart/package.json

then you should NOT run npm instal, has it will cause havoc to you MagicMirror install.
I would do this in this situation:

$ cd /home/pi/MagicMirror/modules/
$ mv mmm-weatherchart mmm-weatherchart.saved
$ git clone https://github.com/szech/mmm-weatherchart.git
$ cd /home/pi/MagicMirror/modules/mmm-weatherchart
$ npm install

$ pm2 restart pm2
$ pm2 logs --lines 100

When it works:

$ cd /home/pi/MagicMirror/modules/
$ rm -rf mmm-weatherchart.saved

Good luck !!

PS @sdetweil : please comment if I am wrong or made mistakes somewhere & thanks for your input.
