Electron CPU usage

@loctruong96 said in Electron CPU usage:

sudo npm install electron@1.4.15 -g

WAIT PATIENTLY FOR ELECTRON TO LOAD IN THE BACKGROUND

a new line appear indicate electron has finished installing

Go to your download folder, exact Magic Mirror 2.1.0

Go to the newly exacted forlder, open another folder named config

Change the file name Config.js.example to Config.js inside the config folder

I keep getting the same issue as @EventHorizon but none of his fixes seem to work (sudo npm install -g electron --unsafe-perm=true) or (nom @latest -g).

I’m starting with a fresh STRETCH install, and get to step 9 (npm install && npm start) where I get the (types/node) fault.

Any ideas?

Thanks all.

@Reotch2 Hello I think this happened because electron was not successfully installed using npm as a global variable. It happened to me too and i had to reinstall electron as a global variable which is the -g at the end is for. Can you confirm that you have successfully install electron ?

@loctruong96 Still no luck. I ran (sudo npm install electron@1.4.15 -g) after the clean install, triple verifying that I had the (-g) on there, and no luck.

-Raspberry Pi 3
-Raspbian Stretch
-Definitely ran (sudo apt-get update)

@Reotch2 hmmm can you try this: npm install npm@latest -g

Reotch2

@loctruong96 Yup… that did the trick. odd… seems like I’ve done the same steps 10 times, but it worked on the 11th.

I can’t seem to find electron under MagicMirror/node_modules/ to verify the version. Where else can I look?

@Reotch2 wow… it seems different people have different version of npm installed and you need the latest one. I will add that into the steps. Thank you for verifying. Good luck on your project!
As for electron version you can confirm by trying “npm list -g” or “npm list” depend on global variable settings of your packages.

Personally, I had some troubles with Stretch, so I went back to Jessie, July release I believe. I’m guessing that most are using Jessie as well. Also, I think that with an installation of MM 2.1.0 you get Electron 1.4.15 by default. That combination is what we have found to work best regarding the CPU usage issue. sudo npm install electron@1.4.15 has worked for everyone. I don’t know why it wasn’t working for you. Perhaps there is something else going on there

With regards to this topic only, you do NOT need or want the latest version of npm.

You can also find the version of npm here MagicMirror/node_modules/electron/dist/version

@Mykle1 Agree, i was thinking the same thing. But some users are experiencing the problem where their npm failed to run install and start which i can only think of updating it which turned out to get it to work so far. I have also indicated a note in the install guide to have people aware of it.
