MagicMirror Failing on Raspberry Pi Zero W Rev 1.1

[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.

@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

[davidgagne]

@sdetweil I’m sorry, but I don’t understand. What exactly is mm? (MagicMirror is running.)

What does npm run server do? (I can visit the IP address of the Pi on my phone or laptop on my home network.)

[davidgagne]

@sdetweil Calling npm run server immediately after connecting via ssh yields:

npm error code ENOENT
npm error syscall open
npm error path /home/dvg/package.json
npm error errno -2
npm error enoent Could not read package.json: Error: ENOENT: no such file or directory, open '/home/dvg/package.json'
npm error enoent This is related to npm not being able to find a file.
npm error enoent
npm error A complete log of this run can be found in: /home/dvg/.npm/_logs/2024-08-05T16_42_00_562Z-debug-0.log

If I switch to the MagicMirror directory and call it, I get this:

> magicmirror@2.28.0 server
> node ./serveronly
