Difficulty getting MMM-Transitfeed working

sdetweil

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 module

cd to the module folder and do the npm install and npm install gtfs (in module folder NOT MM folder!!)
npm install gtfs --save-dev

now, 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 folder

add the config entry for the module
npm start

should 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 limit

During 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?

UncleRoger

@sdetweil
It said “Rebuild Complete” but nothing about sqlite3.

sdetweil

@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-mm

when finished

npm install @electron/rebuild

now the module

cd modules/MMM-Transitfeed
rm -rf node_modules
git checkout package.json
git checkout package-lock.json
npm install

when finished

npm install btfs

when 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.

well, you can follow the steps from

npm install @electron/rebuild
onward

or you can follow all those steps… won’t hurt anything

that I have no clue on…

is this closeable?

Definitely. Thanks again!

@UncleRoger ok, another learning thing…

find the message that best articulates the solution, click the 3 dots to the lower right and select “Mark this post as the correct answer”

you open it, you close it…

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.
