      @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

        [email protected] 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
