      @nowayto yes, but its two steps

      one time without any parameters (test mode)
      and one time with apply

      all you have to do is click/copy the first time and run it
      then do the same on the second if the first ends successfully

        @sdetweil MM doesn’t work.

        I tried a config check but I have this error now.
        I tried to “npm install eslint -g” but the error persist

        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 ‘eslint’

              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

                                      @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

                                          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

                                            @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
