Blank mm after update



  • 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 🙂



  • @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



  • @sdetweil said in Blank mm after update:

    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… 🤔

    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?!



  • 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…
