        @sdetweil fiddled all day today and figured out
        it turned out I did not install or update the dependencies inside the module

        sorry, thanks

          @sdetweil Hello everyone, I haven’t been here for a while and my Magic Mirror was switched off…after I switched it on again I made updates to the modules via remote…but I still don’t have any display for some modules like Tankerkönig…when I start the Mirror it always says “Modules cannot be loaded”.

          Now, as described by sdetweil, there are commands that you have to execute in the modules in question…but unfortunately I haven’t quite understood how I have to do this in the right order?

          It would be really nice if you could explain to me how I have to proceed in order to display the modules again, such as Tankerkönig or mmm-fuel.

          Thank you very much in advance for your help.

          Greetings

          Kussel

          i don´t understand that here:

          npm install ???
          
          where ??? is the library noted in the message Cannot find module ‘???’
          
          | in the example message above, ??? is request
          
          to find this message, look in the output of npm start. or if you use pm2 to launch mm do
          pm2 logs --lines=50
          

          how do I proceed exactly?

            @kusselin find the messages output by mm

            search the messages for one like shown (without the ???)

            find the name of the library in quotes (now u have ???)

            issue a command using that info

                I ran the command as recommended (request was my error as well). I now have this error and MM will not load:

                  @lmac well you ran it in the wrong place… oops

                  do this

                  cd ~/MagicMirror
                  rm -rf node_modules
                  rm package-lock.json
                  npm install
                  

                  then for whatever module was causing problem

                  cd ~/MagicMirror/modules/modulename
                  

                  do the same last 3 steps as above
                  AND THEN

                  npm install request --save

                    Just wanted to say thanks for the fix here.

                    Did an update and hit exactly this with MMM-GmailFeed and the request module.

                    Installed it back (with an audit fix afterwards) and now all up and running again :)

                      @darrenhill said in fix for black screen in 2.16 and later:

                      with an audit fix afterwards

                      don’t do those… many times leave more trouble than they fix…
                      we can’t suppress the audit warning message

                        @sdetweil OK, thanks for the pointer.

                        Always kinda worried when that style of message pops up, for security and suchlike.

                        I see from the update that my node is very much out of date, so now just backing things up before setting the update script onto it to try and bring that up too.
