        @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…

                @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?!

                      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…

                        As long as the errors are no fatal errors that do not prevent the MagicMirror from starting or prevent a certain module from working right, you might chose to ignore them.
                        But the problem is, that when you add something new or update something existing, it becomes more and more difficult to debug and/or correct in case of problems.

                        When you do this:

                        $ pm2 flush
                        $ pm2 restart mm
                        $ pm2 logs --lines 100
                        

                        what is the first error you see ?
                        Perhaps you post the first 50 to 100 lines of the log.

                        But only if you want to spend some time on it, when not that’s fine too.
