Magic Mirror won't load.

[aunrea]

I can’t get the Magic Mirror to load. I went to the .pm2/logs/mm-error.log and this is what I got:

/home/pi/MagicMirror/node_modules/electron/dist/electron js/electron.js: symbol lookup error: /home/pi/MagicMirror/modules/MMM-PIR/node_modules/epoll/build/Release/epoll.node: undefined symbol: _ZN2v816FunctionTemplate3NewEPNS_7IsolateEPFvRKNS_20FunctionCallbackInfoINS_5ValueEEEENS_5LocalIS4_EENSA_INS_9SignatureEEEiNS_19ConstructorBehaviorENS_14SideEffectTypeE

The code above is repeated many more times but I only listed the one time for brevity.

I then went to the .npm/_logs/2009-09-04T00_50_58_410Z-debug.log and this is what was there:

I don’t really understand what anyof that means. What is causing the problem?

@aunrea looks like you might have done an update, but not completely.
modules/MMM-PIR/

in each module folder that has a package.json file, do

npm install

[aunrea]

@sdetweil I had done it before, I believed. I did it again and I still get the same error and the same message.

[sdetweil]

@aunrea mmm-pir is missing completion

[aunrea]

@sdetweil I uninstalled MMM-PIR and reinstall. I have updated npm. I still get that same error message when I have MMM-PIR in my config.js file.

[sdetweil]

@aunrea when u do

cd ~/MagicMirror/modules/MMM-PIR
npm install

What happens?

[aunrea]

@sdetweil I get the message:

[sdetweil]

@aunrea I think u need to do an electron-rebuild in that folder.

I am not near my machine, but electron-rebuild was installed as part of MagicMirror.

See https://forum.magicmirror.builders/topic/10206/mmm-pir-sensor-not-working-with-latest-release-display-does-not-turn-off/7

@sdetweil I got the following error when I followed those instructions:

@aunrea see the instructions w MMM-AssistantMk2.

Great step by step
