        Tried with sudo

        npm seems to see an old version of nodejs but:

        ~/MagicMirror $ node -v
        v22.15.0

        I don’t know what happened.
        If it can help I had first problem after the MMM-SolarPicture
        but I’ve just installed it and configured it through config.js… nothing more than usual…

        but the actual behaviour is that pm2 status says it’s running, but on the monitor I see just the raspbian desktop

          @nowayto two things

          doing test run = true, NO updates will be applied!
          upgrading from version 2.31.0 to 2.31.0

          doing test run changes nothing, its a safety check

          and i wont let you upgrade over the same release accidentally

          so you need to rerun the command and add

          force
          

          to the end

            @nowayto NEVER use sudo with any npm command

            the number in the pm2 status 4311 is the number of restarts

            youve got a mess

            now we HAVE to use sudo to undo it

            cd ~/MagicMirror 
            sudo rm -rf node_modules
            cd fonts
            sudo rm -rf node_modules
            cd ..\vendor
            sudo rm-rf node_modules
            cd ..
            

            lets see about node

            which node
            n 
            q to quit
            nvm 
            

            dont do anything else til we figure out the nodejs problem

              @sdetweil I’m sorry :(

              I did it what you suggest and config:check gave me a module error again. Different than one before

              npm run config:check

              magicmirror@2.31.0 config:check
              node js/check_config.js

              node:internal/modules/cjs/loader:1404
              throw err;
              ^

              Error: Cannot find module ‘ajv’
              Require stack:

              After “require stack” there are other lines, if you need it, tell me.
              Thanks

                i said stop

                we need to fix nodejs so npm install will work

                node -v

                says something
                and npm install says node is different

                i am trying to figure out where node is installed and by who
                system, nvm or n

                you didn’t give me answers to the commands i provided

                  which node gave me
                  /home/MYMIRR/.nvm/versions/node/v22.15.0/bin/node

                  n gave me
                  node/20.18.1

                  Use up/down arrow keys to select a version, return key to install, d to delete, q to quit

                  nvm gave me

                  Node Version Manager (v0.39.5)

                  Note: refers to any version-like string nvm understands. This includes :

                  • full or partial version numbers, starting with an optional “v” (0.10, v0.1.2 , v1)
                  • default (built-in) aliases: node, stable, unstable, iojs, system
                  • custom aliases you define with nvm alias foo

                  followed by a lot of options

                    @nowayto ok nvm and n do the same function but differently

                    i use n in my scripts because it runs everywhere

                    so lets turn off nvm

                    nvm deactivate
                    nvm unload
                    cd ~
                    rm -rf  .nvm
                    

                    now which node
                    should find /usr/local/bin/node

                    now we need n to get to node 22.14.0

                    sudo n 22.14.0
                    

                    now node -v

                    should return 22.14.0

                    if so, do

                    cd  ~/MagicMirror 
                    npm install
                    

                    now MagicMirror should run

                        @nowayto so that sounds like the npm install failed again

                        do it again and show the output

                              I’m sure.I don’t think SolarPicture could be the problem.

                              Yes, the error keep showing

                                #backup MM config and modules list
                                bash -c  "$(curl -sL https://raw.githubusercontent.com/sdetweil/MagicMirror-backup-restore/main/mm_backup.sh)"

                                mv MagicMirror MagicMirror.save
                                #and install MM again

                                  Before writing here I made backups, locally and on github, like you taught me in the past :)

                                  Now I’ll try

                                    That’s incredible… I did it, everything goes good… no issues but when I start it

                                    npm start

                                    magicmirror@2.31.0 start
                                    npm run start:x11

                                    magicmirror@2.31.0 start:x11
                                    DISPLAY=“${DISPLAY:=:0}” ./node_modules/.bin/electron js/electron.js

                                      @nowayto wow!!! NOW i am really confused.

                                      have you rebooted?

                                      if you try the sample config.js

                                      cd ~/MagicMirror/config
                                      mv config.js config.js.save
                                      cp config.js.sample config.js
                                      

                                      and then
                                      npm start

                                      does it run or fail

                                        Sam… I don’t know how to saying it.
                                        I figure out the issue.

                                        After your last message I tried what you suggest.
                                        With the default cfg I had no errors, with mine I had errors.

                                        So I checked again and again the config…
                                        and I find an underscore _ right at the start of the config

                                        npm config:check told me “no syntax errors” and that confusing me.

                                        When I edit it I use nano editor
                                        I do “sudo nano config.js” and I press CTRL + _ to jump at the 250 line.
                                        Might be one of the latest time I opened it and press _ a bit faster than CTRL and I add it for error.

                                        In addition I notice that when I open config.js with nano editor the green cursor is, clearly, at the start of the first line… EXACTLY on the undescore _ and it hides it.

                                        I’m really sorry for bothering you with that.
                                        How can I buy you a coffee ?
                                        Thanks

                                          @nowayto no coffee needed, we found it!!!

                                          please NEVER use sudo inside MagicMirror folder
                                          no reason to use super user , just makes trouble later

                                          so if you fix the config.js in the saved MagicMirror folder then it should run ok too!!!"

                                          ill see what we can do about the misleading message… thanks for your energy here!!!
