      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'
      
      pi@raspberrypi:~/MagicMirror/modules/mmm-weatherchart $ ll /home/pi/MagicMirror/modules/mmm-weatherchart/cache

      4 drwxr-xr-x 2 pi pi 4096 Aug 29 18:49 .

      4 -rw-r--r-- 1 pi pi    6 Aug 29 18:44 .gitignore
      

      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 …

          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) ??

                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 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.
