MagicMirror Failing on Raspberry Pi Zero W Rev 1.1

davidgagne

@sdetweil And just to be thorough, here is my install.log. I don’t know what’s going on with those weird unicode characters in the log. And there are lots of “memory leak detected” that I don’t recall seeing back in May.

                          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

@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.

sdetweil

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

do

npm -v

sdetweil

@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)

davidgagne

@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).

sdetweil

@davidgagne do free -m

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

davidgagne

@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.

davidgagne

@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?

sdetweil

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

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

if you do

cd ~/MagicMirror
npm start

what happens?

davidgagne

@sdetweil Here is the output from npm start called from within MM folder:

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

the config I requested for the forum a couple years ago is a reputation of 2, and then posts will not be moderated.
https://forum.magicmirror.builders/post/104688

this keeps out all the spam, and other nasty stuff…

I review every post that goes thru moderation queue. so I am the bottleneck…

to improve your rep, takes contributing something that other users like enough to vote up your post…

I cannot override that.

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

Starting chromium browser now, have patience, it takes a minute
Chromium_browser not installed

so you have to install, firefox, midiori, or surf
see my scripts doc

https://github.com/sdetweil/MagicMirror_scripts?tab=readme-ov-file#switch-to-the-midori-or-firefox-or-surf-browser

davidgagne

@sdetweil Right. I did all that – uninstalled chromium, installed Firefox, and edited installers/mm.sh – as part of my installation process. I’m not sure why it’s still looking for chromium; I assume it’s hard coded somewhere in the MM startup script.

sdetweil

@davidgagne not hard coded…

    # if not set
    if [ "$external_browser." == "." ]; then
        # start chromium
        echo "Starting chromium browser now, have patience, it takes a minute"

it IS case sensitive and ALSO needs the export
unlike Windows in linux environment variables are not inherited by default…

show me the mm.sh

davidgagne

@sdetweil Here’s the entire mm.sh file:

#!/bin/bash
# This file is still here to keep PM2 working on older installations.
cd ~/MagicMirror
export external_browser=firefox
DISPLAY=:0 npm start

sdetweil

@davidgagne hm… no idea really
you can test the script with

cd ~/MagicMirror
installers/mm.sh

and

cd ~/MagicMirror
export external_browser=firefox
npm start

never seen it fail tho.

davidgagne

@sdetweil If electron hasn’t been required for years, then why does a fresh install of everything generate tens of thousands of “can’t find electron” lines in MagicMirror-error.log?

sdetweil

@davidgagne the default install is to use electron.

We made it optional, so the install would not just fail.
and my script makes other browsers available as alternatives.

if you do the manual install, there is nothing to fix the package.json still trying to use electron. and it errors out.

now you can clear the pm2 logs

pm2 flush

and then see info from future runs

davidgagne

@sdetweil Okay. Next issue is that MagicMirror-out.log is always empty. I recall that I could find lots of information in there the last time I was setting up a MM, but this time it’s always just blank. (The MagicMirror-error.log file is, sadly, useless because it’s just filled with tens of thousands of lines of Error: Cannot find module 'electron'.)

Any idea why MagicMirror-out.log is always empty?

sdetweil

@davidgagne out is empty cause mm never started

Does
npm run server
Work
