      @sdetweil I didn’t update MM since I’ve installed it months ago, so I suppose it wasn’t that. Might be it updated automatically?

      I remember you told me to use a “temp fix” to solve a problem.
      Now I’ll follow your guide in the post to update it.
      Thanks

            @sdetweil I’m sorry for the question: that script?

            bash -c “$(curl -sL https://raw.githubusercontent.com/sdetweil/MagicMirror_scripts/master/upgrade-script.sh)”

            Thanks

              @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

                      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’

                              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

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

                                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)

                                  @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
