      @nowayto >Node.js v20.18.1

      2.31.0 requires node 22.14 or above

      how did you get here?

      also you are on 2.31.0-develop

        @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

                    @nowayto show me the ~/MagicMirror/installers/upgrade.log

                    note: I had a typo in log filename

                    and then do

                    cd ~/MagicMirror

                        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
                                  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
