      Yes I do! But unfortunately I’m not very familiar with linux. I’ll give it a try. Thank you
      EDIT: npm install del doesn’t work for both modules.

      EDIT2: after the installation of “del”, the MM² come up again. But there is still no weatherchart.

      EDIT3: cd ~/MagicMIrror && npm start dev
      console issued the following text --> { [Error: EACCES: permission denied, open ‘/home/pi/MagicMirror/modules/mmm-weatherchart/cache/map-1581788960498.png’]
      errno: -13,
      code: ‘EACCES’,
      syscall: ‘open’,
      path: ‘/home/pi/MagicMirror/modules/mmm-weatherchart/cache/map-1581788960498.png’ }

      I tried ‘sudo chmod -R 777 .’ inside the mmm-weatherchart module directory. But this also dosn’t help.

        generaly caused by

        maybe:

        1. you have installed this module with root account (by using sudo ?)
        2. git clone with sudo
        3. npm install with sudo

        notes: ALL modules and MagicMirror program sould be installed with user account (pi with raspberry)
        and NOT with root account (sudo command)

        If you install with sudo command is equal to modify or rewrite a file in windows system -> you can’t access or modify it with simple windows user account

          I installed this module yesterday and did a little debugging. The request for the graphic works ok (code=200), but the saving to disk doesn’t work for some reason.

          The web URL error also means not found. I am away from my system til late today before I can look at it again

            ok, we have a timing problem… the file is written, but erased

            workaround

            change these lines in node_helper.js

            			http.get(options, function (response) {
            				var pngFiles = payload.mmDir + 'modules/mmm-weatherchart/cache/*.png';
            				del([pngFiles]);
            

            to

            			var pngFiles = payload.mmDir + 'modules/mmm-weatherchart/cache/*.png';
            			del.sync([pngFiles]);
            			http.get(options, function (response) {

              @Bugsounet ok thank you for the explanation. I tried it with and without sudo, but it doesn’t matter. I have left the last clone of the module without the sudo command.

                Today it was very weird, I started my MM² to reinstall the module as @Bugsounet said, and the weatherchart was visible (the first time on my MM²)! After that I decided to change the region of the weatherchart, unfortunately the weatherchart is now gone again. No region is working reliable.

                      @prototype0815 better solution, download my fork of the module with both fixes

                      stop your magicmirror

                      cd ~/MagicMirror/modules
                      mv mmm-weatherchart mmm-weatherchart.original
                      git clone https://github.com/sdetweil/mmm-weatherchart.git
                      cd mmm-weatherchart
                      npm install
                      cd ~/MagicMirror
                      npm start

                        Hey guys thank you all for your help! The sdetweil fork is working very well if “del” is installed too.
                        :handshake: :thumbs_up: great community
