Difficulty getting MMM-Transitfeed working

[UncleRoger]

Re: MMM-transitfeed - upcoming departure board for most transit agencies

I tried to install this a while back but ran into problems. I had difficulty initially because when I tried to install it, I got a message back saying the gtfs stuff needed a newer node.js. I tried updating it and that went… badly. I managed to get things back the way they were and gave up for a bit. (Had a lot going on in my life at the time.)

I’ve decided to try again (I want to get it working for my son who goes to school/work on public transit) and this time I set up a fresh install. New Raspberry PiOS, new MM install, nothing else done. Here’s what I’ve done so far:

# Update system

sudo apt update
sudo apt full-upgrade

# Install MagicMirror

bash -c  "$(curl -sL https://raw.githubusercontent.com/sdetweil/MagicMirror_scripts/master/raspberry.sh)"

# update Node/NPM

sudo npm install -g n
sudo n lts
sudo n latest
sudo n prune

# Install transitfeed

cd ~/MagicMirror/modules
git clone https://github.com/bnitkin/MMM-transitfeed.git

# Install gtfs

cd ~/MagicMirror                     # Enter magicmirror project directory
npm uninstall gtfs-realtime-bindings # Now part of gtfs
npm install gtfs --save-dev          # Force update to latest version

# Update better-sqlite3

cd ~/MagicMirror
rm -r node_modules/better-sqlite3/
npm install better-sqlite3 --build-from-source --runtime=electron --target=26.4.3 --dist-url=https://electronjs.org/headers --force

And here’s the error I’m getting:

[2024-06-21 11:14:44.933] [ERROR] (node:53839) UnhandledPromiseRejectionWarning: Error: The module '/home/pi/MagicMirror/node_modules/better-sqlite3/build/Release/better_sqlite3.node'

It seems like I need an even newer version of better_sqlite3? Or maybe an older version of node.js?

How to get MMM-transitfeed working on a new installation of MagicMirror (based on @sdetweil’s assistance)

These are the steps I went through to get the module working after encountering version mismatch errors:

Note that I was starting with a clean install of Raspberry PiOS. I made no changes prior to the steps outlined below:

First, I installed MagicMirror using Sam Detweil’s script:

bash -c  "$(curl -sL https://raw.githubusercontent.com/sdetweil/MagicMirror_scripts/master/raspberry.sh)"

Next, I installed the transitfeed module:

{
  cd ~/MagicMirror/modules
  git clone https://github.com/bnitkin/MMM-transitfeed.git
}

Then this reset the libraries:

{
  cd ~/MagicMirror
  rm -rf node_modules
  git checkout package.json
  git checkout package-lock.json
  npm run install-mm
}

I installed the electron rebuild package:

npm install @electron/rebuild

Next, I reset the module info:

{
  cd ~/MagicMirror/modules/MMM-transitfeed
  rm -rf node_modules
  git checkout package.json
  git checkout package-lock.json
  npm install
}

At this point, I installed gtfs:

{
  cd ~/MagicMirror/modules/MMM-transitfeed
  npm install gtfs
}

And lastly, I rebuilt sqlite3:

{
  cd ~/MagicMirror/modules/MMM-transitfeed
  ../../node_modules/.bin/electron-rebuild
}

Here I added the default config from the module’s github page to my config.js and started the mirror. It worked!

Many thanks to Sam for his patience, knowledge, and caring assistance.

@UncleRoger run npm rebuild in the module folder

this module has a binary that has to match the electron version.
the distributed version does not.

[sdetweil]

@UncleRoger or

better

cd ~/MagicMirror
npm install @electron/rebuild
cd modules/MMM-Transitfeed
…/…/node_modules/.bin/electron-rebuild
cd ~/MagicMirror

and restart MagicMirror however  you do that

[UncleRoger]

@sdetweil

I gave that a bash and am still getting the same error. I even wiped the system and started from scratch just in case I’d done something to make things worse.

[sdetweil]

@UncleRoger hm… I installed, did the npm install gtfs

ran, failed as version mismatch
I then did the

../../node_modules/.bin/electron-rebuild 
✔ Rebuild Complete

restart mm and no problems, using the default config

[UncleRoger]

@sdetweil

I appreciate the help, as always… I wiped the system again, reinstalled the OS and MM, did the rebuild. Still the same error except the version numbers are different:

[2024-06-21 15:30:32.001] [ERROR] (node:53456) UnhandledPromiseRejectionWarning: Error: The module '/home/pi/MagicMirror/node_modules/better-sqlite3/build/Release/better_sqlite3.node'
was compiled against a different Node.js version using
NODE_MODULE_VERSION 127. This version of Node.js requires
NODE_MODULE_VERSION 121. Please try re-compiling or re-installing
the module (for instance, using `npm rebuild` or `npm install`).

I should mention that this is on a Pi4 (probably 2gb) with no other modules installed.

Maybe it’s just not meant to be.

[sdetweil]

@UncleRoger what folder are you in when you do the electron-rebuild?

[UncleRoger]

@sdetweil

The MMM-transitfeed module directory:

{
  cd ~/MagicMirror
  npm install @electron/rebuild
  cd ~/MagicMirror/modules/MMM-transitfeed
  ../../node_modules/.bin/electron-rebuild
  cd ~/MagicMirror
}

I basically copy-and-pasted that.

[sdetweil]

@UncleRoger and when the electron-rebuild ran it should have said
something about sqllite
and rebuild complete, like mine above

[UncleRoger]

@sdetweil

Nothing about sqlite but it did say “Rebuild Complete”:

pi@MagicMirrorDev:~/MagicMirror $ {
  cd ~/MagicMirror
  npm install @electron/rebuild
  cd ~/MagicMirror/modules/MMM-transitfeed
  ../../node_modules/.bin/electron-rebuild
  cd ~/MagicMirror
}

added 81 packages in 11s

253 packages are looking for funding
  run `npm fund` for details
✔ Rebuild Complete
pi@MagicMirrorDev:~/MagicMirror $ 

This time around, I didn’t do the sqlite update:

{
  cd ~/MagicMirror
  rm -r node_modules/better-sqlite3/
  npm install better-sqlite3 --build-from-source --runtime=electron --target=26.4.3 --dist-url=https://electronjs.org/headers --force
}

But I don’t think it worked any better when I did. I’ll try that and then do the rebuild.
