Electron CPU usage

MichMich · Dec 5, 2017, 7:39 AM

For anyone running into this issue, run the following command from your MagicMirror folder:

 npm install electron@1.4.15

One more data point: The Pi behind my office mirror was doing okay, until I enabled the MMM-Snow module. Short version is that I had to downgrade Electron to 1.4.15 but now it’s running pretty well with 50 snowflakes.

@schlachtkreuzer6 I had the same error when I downgraded. However, it did install and I am able to run the Magic Mirror process. I am getting a temperature warning. I’ll experiment a bit to see if I can narrow that down.

@bhepler Yeah funny!
But you´re right. It install electron and the temperature sinks from 82-85°C to 52-55°C and the animations are smooth. Only the error massage is strange!

@schlachtkreuzer6 Technically, they’re not error messages. They’re warnings. If they become serious, then they will be promoted to errors.

@MichMich Got a similar issue as reported by @schlachtkreuzer6, unfortunately I now have a black screen when starting. Logs show “WARNING! Could not load config file. Starting with default configuration. Error found: Error: Module version mismatch. Expected 50, got 54”. Any suggest on how to revert?

Update: Managed to successfully revert back but doing a " npm install electron".

i have a problem at downgrading:

pi@magicmirror:~ $ cd ~/MagicMirror
pi@magicmirror:~/MagicMirror $  npm install electron@1.4.15

> electron@1.4.15 postinstall /home/pi/MagicMirror/node_modules/electron
> node install.js

- @types/node@7.0.43 node_modules/@types/node
magicmirror@2.1.3 /home/pi/MagicMirror
└── electron@1.4.15  invalid

How can i fix that ?

Hey guys,

(first, sorry for my english. i hope you understand what i am trying to tell^^)

i have got the same problem as u all.

So i tried to fix it with using MagicMirror 2.1.0 and electron 1.4.15

Unfortunately i am not the best programer, so sometimes i don’t know if i’m doing anything right.

Well, i tried the option as shown in this thread on page 18 (https://forum.magicmirror.builders/post/28875)

That gave me some npm errors when i type “npm start”.
So i tried to use this guide: https://forum.magicmirror.builders/topic/5274/how-to-manually-install-mm-on-your-pi-for-absolute-beginners

But it gave me the same errors.

Step by step i did:

rename the original MM-Folder to “MagicMirror_OLD”
Downloaded this https://github.com/MichMich/MagicMirror/archive/v2.1.0.zip
extract it and rename it to “MagicMirror”
cd in this folder and type “npm install”
after installing was done i typed “npm start” and got this:

pi@MagicMirror:~ $ cd ~/MagicMirror/
pi@MagicMirror:~/MagicMirror $ npm start

> magicmirror@2.1.0 start /home/pi/MagicMirror
> electron js/electron.js

Another time i tried as shown on page 18. it was showing me, that i was using electron 1.4.15, but when i typed the “npm start” it shows me the same message as above.

i don’t know what to do :( would be quite nice, if u guys could invest some time to solve my problem together. thank you very much :)

edit:

the “npm-debug.log” is here:
