    `@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] Flushing /home/dvg/.pm2/pm2.log
    [PM2] Logs flushed
    

    Then pm2 status gave me:

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

    At this point I’m going to give up and go back to square one and flash the drive again and start over. Ugh.

      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.

              @davidgagne thanks.

              5 and 6 are optional
              as 7 can be done with nano over ssh

                 scroll down with keyboard arrow keys
                 hit enter to add a line
                 type the export line
                 ctrl-x to exit nano, yes to save contents
              

              8 and 9 over ssh
              9 pm2 can be run from any folder location

                @sdetweil Is there any reason why this same procedure would not work on a 3B+? I’ve tried with multiple different versions of the OS but it always seems to get stuck on “Updating packages …” and – as far as I can tell – there’s nothing meaningful in install.log. Is this install script unique to the Zero W?

                  @davidgagne no. the script works of any Debian based os. pi0 is SLOOOOOW…
                  but pi 3b+ should be ok. there should be a moving <-> while it’s updating… (haven’t figured out how to make that stand out more)

                  the script is doing apt get update, apt upgrade . this could take a while based on how much change since distro was released. over wifi, nothing I can do to speed it up.

                  I’ve tested on all the pi models. except the pi 1.
                  on odroid, Jetson nano, a chrome box and book running linux and a bunch of x86 distros., and macos Intel and arm.
                  I also tested on my arm chromebook, with the extra Ubuntu installed. install worked and server mode worked. no ui

                  if there is a problem, I’ll fix it. I’ll setup my 3b later.

                    @sdetweil Right. That’s my confusion. I have been able to run the script a dozen (or more) times on the Zero W, but it always fails on the 3B+, which I had assumed would be faster / better than the Zero W.

                      @davidgagne always fails?

                      what os? I’d pick the 32 it due to memory size

                      send me the install.log.
