Blank mm after update

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

@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.

this is all volunteer… you could post an issue to the module owners github repo… maybe he or someone else will respond… I am like you, just another user…

@sdetweil Thanks! This worked for me

I should type faster :-)

sdetweil

@evroom think u have good instructions…

ps, 2 of my three systems do not have pi as the user, so the path is wrong, and in the module defaults too

Yes, I assumed user pi and the install under the user pi home directory.
Will try to remember that in the future.
Tilde for the home directory should work on all platforms, is my understanding.

~/MagicMirror

My keyboard is lacking a tilde and I always forget the right keystrokes.
So /home/pi is faster. :-)

@evroom I sat right now and installed a new calendar module and suddenly the mmm-weatherchart started working… :thinking_face:

Did the $ pm2 logs --lines 100 and got a lot of errors, but I guess because everything’s working fine so don’t have to bother right now?!

kvicksson

And of course it didn’t work now when I tried to switch back to default calendar module and then back to the other calendar module…
