MMM-Hotword causing Mirror to blackout

budddesilva · Dec 23, 2018, 3:04 AM

Hi there, I’ve looked all over the forum for an answer to my problem. The MagicMirror works fine with the MMM-AssisstantMk2, I then added the Hotword module into the config file and the program starts… but just a black screen. This is what’s displayed on the terminal. Does anyone see what I’m doing wrong?

MagicMirror will not quit, but it might be a good idea to check why this happened. Maybe no internet connection?

Hold on, I’m wrong here. I don’t think it’s the Hotword module causing the blackout. I just removed that part from the main config file and still get the same issue. I will try and look back in the forum related to MMM-AssistantMk2.

@budddesilva
It seems not installed properly. Some dependencies(like lpcm) are missed. Complete installation as documented carefully again.

budddesilva · Dec 23, 2018, 7:40 PM

@sean
Thank you for your reply. I did a fresh install of Raspbian Stretch, did all the updates and installed all the dependencies one by one. However, every time I add the default configuration for MMM-Hotword into the main config.js file… I get the black screen. I can safely say MMM-Hotword is the culprit because the mirror works fine without it in the config.js file. Do you have an idea of what’s causing this?

This is what I have in my config.js file

The error I get when running the mirror with the Hotword module says it cannot find the snowboy module… I didn’t have any problems when I installed snowboy. I rebuilt this without any problems using the code below.

cd ~/MagicMirror/modules/MMM-Hotword/node_modules/snowboy
npm install --save-dev electron-rebuild
npm install nan
./node_modules/.bin/electron-rebuild

You should be doing npm install in the MMM-AssistantMk2 folder

budddesilva · Dec 23, 2018, 7:48 PM

Thanks for the reply @sdetweil . So, do you mean like… ?

cd ~/MagicMirror/modules/MMM-AssistantMk2
npm install --save-dev electron-rebuild
npm install nan
./node_modules/.bin/electron-rebuild

sdetweil · Dec 23, 2018, 7:52 PM

Yes, but I don’t think u need that last command. The package.json in the module folder is used for installing the dependencies at the right level. U might have to delete the MMM-AssistantMk2/node_modules folder to get it done cleanly

@budddesilva said in MMM-Hotword causing Mirror to blackout:

Error: Cannot find module ‘snowboy’

This says you didn’t (or failed) npm install of modules. snowboy is included in MMM-Hotword and you havn’t installed it completely. Was there any suspicious error when you install MMM-Hotword?

budddesilva · Dec 23, 2018, 8:07 PM

Ok. These are the steps I took.

Removed the MMM-AssistantMk2/node_modules folder.
npm install in the MMM-AssistantMk2 folder
cd ~/MagicMirror/modules/MMM-AssistantMk2
npm install --save-dev electron-rebuild
npm install nan
Received the following error

Ran the npm rebuild command in the MMM-AssistantMk2 folder
Still the same error as before.

What do you think @sdetweil ?

A Former User · Dec 23, 2018, 8:32 PM

@budddesilva

sudo apt-get update
sudo apt-get upgrade
sudo apt-get install build-essentials
sudo apt-get install gcc-5

do this first.

Then,

sudo apt-get install libasound2-dev sox libsox-fmt-all

Then,

cd ~/MagicMirror/modules/MMM-AssistantMk2
npm install --save-dev electron-rebuild
./node_modules/.bin/electron-rebuild

I wish you have a luck. Happy holidays.
