      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

                      @nowayto wild, lets do this… intall MM again, but save the current…

                      #backup MM config and modules list
                      bash -c  "$(curl -sL https://raw.githubusercontent.com/sdetweil/MagicMirror-backup-restore/main/mm_backup.sh)"
                      #rename the MagicMirror folder out of the way
                      cd ~
                      mv MagicMirror MagicMirror.save
                      #and install MM again
                      bash -c  "$(curl -sL https://raw.githubusercontent.com/sdetweil/MagicMirror_scripts/master/raspberry.sh)"
                      #restore the  MM config and modules
                      bash -c  "$(curl -sL https://raw.githubusercontent.com/sdetweil/MagicMirror-backup-restore/main/mm_restore.sh)" 
                      

                      then

                      cd ~/MagicMirror
                      npm start

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

                        Now I’ll try
