      @sdetweil Ah. I see that. But … I don’t think the Jeopardy module is the main problem here. I’d prefer to simply remove that and try to get back to where I can even get MM to run in the first place; then I’ll screw around with adding modules. As it is I still can’t get MM to even run at all (plus all the restarts).

        @sdetweil Am I wrong about this? It actually appears that ‘electron’ is the missing module. But that’s not in /modules it’s in /js … Do I follow the same npm init steps to get it?

          @davidgagne no the electron missing is a problem in MagicMirror code…

            @davidgagne ok, lets clean up and restart

            all command line commands

            pm2 flush (to get clear out the old logs) 
            
            pm2 status
            
            cd ~/MagicMirror
            npm start 
            

            all show work… and if you loaded the missing library in the MMM-Jeopardy module then all should be ok.

            then ctrl-q on the MM screen should stop it

            then

            pm2 restart 0
            

            and MM should come back up

                `@sdetweil Sadly that didn’t seem to work at all.

                pm2 flush gave me:

                [PM2] Spawning PM2 daemon with pm2_home=/home/dvg/.pm2
                [PM2] PM2 Successfully daemonized

                [PM2] Logs flushed
                

                Then pm2 status gave me:

                Then I did cd ~/MagicMirror/ and ran npm start which spit out this:

                  no… just fix the MMM-Jeopardy module as I suggested yesterday

                  two steps
                  you only did 1

                  … the more concerning part is that pm2 didn’t get setup as a service and start on boot… i haven’t looked at the log yet

                      @sdetweil I understand what you’re saying about fixing the Jeopardy module, but I really think that’s secondary to not getting MM to run in the first place (and it not starting as a service on boot). Once I get MM running reliably in the first place I will play around with modules. :-)

                        How to Get MagicMirror to Run on a Raspberry Pi Zero W Rev 1.1

                        Late-May 2024

                        Huge thanks to @sdetweil for all his help!


                        1. Flash card with Legacy 32-bit.
                        2. Connect via ssh to run script:
                          bash -c  "$(curl -sL https://raw.githubusercontent.com/sdetweil/MagicMirror_scripts/master/raspberry.sh)"
                          

                          Answer yes to disable screen saver and use pm2 questions.

                        3. Remove chromium with:
                          sudo apt-get remove chromium-browser
                          sudo apt autoremove
                          
                        4. Add Firefox with:
                          sudo apt-get update
                          sudo apt-get install firefox-esr
                          
                        5. Enable VNC using GUI (Interface Options):

                          sudo raspi-config

                        6. Connect via TigerVNC (Apple app)
                        7. Edit installers/mm.sh via VNC using Pi's baked-in text editor by adding:
                          cd ~/MagicMirror
                          export external_browser=firefox
                          DISPLAY=:0 npm start
                          
                        8. Execute fix'em-up script:
                          bash -c "$(curl -sL https://raw.githubusercontent.com/sdetweil/MagicMirror_scripts/master/fixuppm2.sh)"
                          
                        9. cd ~/MagicMirror/
                          pm2 start MagicMirror
                          
                        10. sudo reboot

                        Note: On my Pi Zero W it takes a solid ten minutes from reboot to actually seeing MM output via HDMI.
