      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

                  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

                          @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!!!

                                  @nowayto ok, I’ve found the error producer
                                  and I’ll propose a fix…

                                  I think this might have been more useful lol

                                    @sdetweil Ok but I wanna just offer a coffe for your kind and your time spent with that.

                                    Do you suggest me to fix the old magic mirror folder or just rm it?

                                      @nowayto if you have everything working, you can rm it

                                      i was just saying you could prove this change would fix the prior install

                                      i do this for fun, really! pay it forward, help someone else on whatever when you can.

                                            @rkorell Again, thank you Sam.
                                            I know what you mean, I usually act as you said.
                                            I like to help other, in the subject where I have knowledge.
                                            So, thank you again
