Difficulty getting MMM-Transitfeed working
-
There is no joy in mudville.
Here’s what I did with a fresh install of PiOS (Raspberry Pi 4 2gb):
pi@MagicMirrorDev:~/MagicMirror $ history 1 { sudo apt update; sudo apt full-upgrade; } 2 bash -c "$(curl -sL https://raw.githubusercontent.com/sdetweil/MagicMirror_scripts/master/raspberry.sh)" 3 sudo nmtui 4 sudo shutdown -r now 5 sudo nmtui 6 sudu shutdown -r now 7 sudo shutdown -r now 8 { cd ~/MagicMirror/modules; git clone https://github.com/bnitkin/MMM-transitfeed.git; } 9 cd .. 10 { 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 } 11 { 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 } 12 { sudo npm install -g n; sudo n lts; sudo n latest; sudo n prune; } 13 { 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 } 14 cd $HOME/MagicMirror; 15 DISPLAY=:0 npm start 16 npm run config:check 17 DISPLAY=:0 npm start 18 npm run config:check 19 DISPLAY=:0 npm start 20 npm run config:check 21 DISPLAY=:0 npm start 22 { 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; } 23 { cd ~/MagicMirror; npm install @electron/rebuild; } 24 { cd ~/MagicMirror/modules/MMM-transitfeed; ../../node_modules/.bin/electron-rebuild; cd ~/MagicMirror; } 25 DISPLAY=:0 npm start 26 history pi@MagicMirrorDev:~/MagicMirror $The nmtui stuff is to set the IP address (which I did wrong a couple of times) and then I mucked up the config.js putting in the transitfeed module stuff.
Here’s the log from trying to run it at the end (it’s basically the same):

(rejection id: 8)I’m thinking I might give it another go from scratch without worrying about the IP address and catching all the output from each command.

Could you check that I’m doing things correctly? These are the commands I’m using to get from a fresh OS to MM with transitfeed:
# 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)" # NOTICE ON INSTALL: npm install -g npm@10.8.1 # 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 } # Rebuild Electron? { cd ~/MagicMirror npm install @electron/rebuild cd ~/MagicMirror/modules/MMM-transitfeed ../../node_modules/.bin/electron-rebuild cd ~/MagicMirror }Thanks so much for your help!

@UncleRoger ok, simpler
flash sd card with
use my script to install MM (do nothing before, it does the update and adds whats needed for MM)
npm start to prove MagicMirror is working
clone the modulecd to the module folder and do the npm install and npm install gtfs (in module folder NOT MM folder!!)
npm install gtfs --save-devnow, need electron rebuild
cd …/… # magicmirror folder
npm install @electron/rebuild
cd - # go back to module folder
…/…/node_modules/.bin/electron-rebuild
wait, should show sqlite
rebuild complete
cd - # back to MM folderadd the config entry for the module
npm startshould work
-
When you say “module folder”, you mean (in this case) ~/MagicMirror/modules/MMM-transitfeed not ~/MagicMirror/modules/ right? I’m pretty sure, but better safe than sorry.
Thanks!

@UncleRoger correct the module’s folder

Still no luck. 8^(
I was getting a bunch of errors during the MM install which some googling suggested might be due to insufficient power (which is odd because I was using a big power supply) so I switched to an RPi power supply and still got the same errors. So maybe they’re somehow related? The errors are:
During MM Install:
(node:27144) MaxListenersExceededWarning: Possible EventEmitter memory leak detected. 11 close listeners added to [TLSSocket]. Use emitter.setMaxListeners() to increase limitDuring the Electron stuff:
(node:42678) MaxListenersExceededWarning: Possible EventEmitter memory leak detected. 11 close listeners added to [TLSSocket]. Use emitter.setMaxListeners() to increase limit -
@UncleRoger it’s an npm bug, nothing fatal
did you see the rebuild messages?
-
@sdetweil
It said “Rebuild Complete” but nothing about sqlite3. -
@UncleRoger ok, let see if we can clean up and try again
so we are going to reset the MM loaded libs and the module loaded libs
cd ~/MagicMirror rm -rf node_modules git checkout package.json git checkout package-lock.json npm run install-mmwhen finished
npm install @electron/rebuildnow the module
cd modules/MMM-Transitfeed rm -rf node_modules git checkout package.json git checkout package-lock.json npm installwhen finished
npm install btfswhen finished
../../node_modules/.bin/electron-rebuild -

That worked! Yay!
Thank you so very much! I really appreciate all your help. You are truly amazing.
My next step is to figure out how to get to the same point with my actual dev system before making the same changes to the production system. That and how to get it to work with my local transit system’s feeds.
