Node.js Compile Version Mis-Matches?

[pillbug22]

I’m trying to MMM-MP3Player up and running to play music locally.

Following the install instructions on GitHub, I added the 3 dependencies listed, then cloned the MMM-MP3Player project down as instructed.

Now when starting up the MagicMirror, I’m getting the following:

[2020-06-03 09:44:27.792] [LOG]    Whoops! There was an uncaught exception...
[2020-06-03 09:44:27.793] [ERROR]  Error: The module '/home/pi/MagicMirror/modules/MMM-MP3Player/node_modules/usb/build/Release/usb_bindings.node'
was compiled against a different Node.js version using
NODE_MODULE_VERSION 64. This version of Node.js requires
NODE_MODULE_VERSION 73. Please try re-compiling or re-installing
the module (for instance, using `npm rebuild` or `npm install`).

Based on a similar issue/troubleshooting I found, I have done:

cd /MagicMirror/modules/MMM-MP3Player
rm -rf node_modules/usb
npm cache clear
rm package-lock.json
npm i

It does some work to rebuild/install the MMM-MP3Player module again, but I still receive the same error when starting up the MagicMirror next time.

I then tried the 2nd and 3rd highest proposed solutions on there (electron-rebuild and –update-binary, but wind up with same error each time when trying to launch the MagicMirror.

I’m guessing there is a different file that needs to be rebuilt, or a way to force using a specific version of Node.js?

@pillbug22 do

cd ~/MagicMirror
npm install electron-rebuild
node_modules/.bin/electron-rebuild

@sdetweil : are you sure of this ?
install and execute electron rebuild inside main MM core !?

[sdetweil]

@Bugsounet sure, it will find what it needs to rebuild

[A Former User]

and scan … ALL modules …

[sdetweil]

@Bugsounet so, it will do it quickly… go get some coffee… everything not done in 2 seconds! lol

[A Former User]

lol

so the better thing is that :
install electron rebuild inside the module desired (there MMM-MP3Player)

cd ~/MagicMirror/modules/MMM-MP3Player
npm install electron-rebuild

and execute it

./node_modules/.bin/electron-rebuild

[sdetweil]

@Bugsounet better not to install it 12 times , just one in MM, then maybe use in module folder…

too many modules need rebuild

I have already tried it but sometimes … it remakes the queue with the other modules and crashes … that’s why I abandoned this method. otherwise on principle i agree with you :)

after … like i say : “If it want to works like this … let’s go on !”

I think MM needs to escape from the dependency of Electron. (Frankly, it is needed only for fullscreen kiosk front, not using any advanced benefits of Electron itself)
or at least modules need to use worker-threading or spawning child process which would be independent from Electron process environment to work with node’s native-modules.
