node serveronly works, but npm start doesn't

[nealterrell]

How can I go about diagnosing an issue where node serveronly works fine, but npm start (whether on a terminal or via pm2) fails silently? The only log information from npm is this:

> magicmirror@2.10.0 start /home/pi/MagicMirror
> ./run-start.sh
[15:42:38.586] [LOG]    Starting MagicMirror: v2.10.0
[15:42:38.595] [LOG]    Loading config ...
[15:42:38.600] [LOG]    Loading module helpers ...
[15:42:38.689] [LOG]    Initializing new module helper ...
[15:42:38.690] [LOG]    Module helper loaded: MMM-Remote-Control

(process terminates)

It’s something to do with the MMM-PIR-Sensor module – removing it from config fixes npm start – but the module works fine in node serveronly mode, so I am having trouble identifying the problem.

@nealterrell did u install 2.10 or upgrade? Did u use one of the scripts?

What pi is this

run-start.sh had been updated to auto detect serveronly in config.js, or on systems where electron doesn’t work.

Edit the run-start.sh and add a space and -x to the first line

And then do npm start

@sdetweil Thank you for your reply. Raspberry Pi 4. Initially I upgraded with git pull && npm install, but I found your upgrade script and ran that. Now I added -x to run-start, and this is the output:

> magicmirror@2.10.0 start /home/pi/MagicMirror
> ./run-start.sh

I added some logging to app.js where it loads modules, and the process terminates on the line Module = require(helperPath) when helperPath is the MMM-PIR-Sensor module.

I don’t expect you to diagnose every misbehaving module, so I’ll continue to dig and see what went wrong. Any advice would be appreciated; especially regarding why there’s no issue with node serveronly.

@sdetweil I found that MMM-PIR-Sensor was failing when requiring onoff, so I wiped its node_modules, npm install, and now everything is fine. Sorry for wasting your time!

@nealterrell but my script was supposed to run the npm install for you.

Can u send me the installers/upgrade.log

Same Id as here on Gmail. Thx
