MagicMirror Failing on Raspberry Pi Zero W Rev 1.1

@sdetweil Here are the contents of the package.json and run-start.sh files. Note that I have not edited anything. This is exactly how they came from the installation process.

                          Runtime Edition

        PM2 is a Production Process Manager for Node.js applications
                     with a built-in Load Balancer.

                Start and Daemonize any application:
                $ pm2 start app.js

                Load Balance 4 instances of api.js:
                $ pm2 start api.js -i 4

                Monitor in production:
                $ pm2 monitor

                Make pm2 auto-boot at server restart:
                $ pm2 startup

                To go further checkout:

@sdetweil I scoured the forums and found someone else complaining about electron being missing.

I ran this sudo npm i -g npm@6 and now it seems to be working fine.

@davidgagne that makes no sense… the latest version of npm is 10.x
and you just installed v6… (maybe)

do

npm -v

@davidgagne said in MagicMirror Failing on Raspberry Pi Zero W Rev 1.1:

MaxListenersExceededWarning: Possible EventEmitter memory

that is an npm bug… nothing we can do anything about. no impact on install

unicode… those are shell escape codes for color (the colors don’t show in the file, only on the actual console)

@sdetweil npm -v returns 6.14.18 (and it takes a solid 45 seconds to do that, which seems like a very long time for such a simple command, even on a Zero).

@davidgagne do free -m

pi is small on memory, so running off sd card a lot…

davidgagne · Aug 1, 2024, 6:02 PM

@sdetweil I was wrong. It’s not working fine.

It was working fine. Then I rebooted to make sure everything was fine. Comes back up with no problem.

Then I ssh-ed to it, installed a module, ran npm install inside the new module’s directory, execute pm2 start MagicMirror, and now MM crashes again looking for electron.

So frustrating.

@sdetweil Can I run sudo npm i -g npm@10 to upgrade to v10?

Also: Can you help with getting my forum account upgraded so I don’t have all my posts queued for approval?

pm2 start MagicMirror, and now MM crashes again looking for electron.

if you do

cd ~/MagicMirror
npm start

what happens?
