Errors trying to run MM on Pi3

bhepler

@Esinem It seems that you do not have Electron installed on your Pi. If you install electron, it should overcome that error.

First, go to your home directory: cd ~
Then install electron: npm install electron@1.4.15
Once that is complete, try starting the mirror again.

Good luck!

NOTE: This won’t work (see below). Instead cd ~/MagicMirror.

Thanks but it didn’t seem to work :-( I tried what you said and then continued with the steps in the tutorial but as you can see it failed. I tried running it again but more errors.

I’m off to bang my head on a wall! :-) I’m quite prepared to believe I’m doing something idiotic as I’m a total Pi/Raspbrian/Python virgin.

@Esinem you installed it in /home/pi instead of /home/pi/MagicMirror

Esinem

@strawberry-3.141 Thanks. Isn’t that what I was told to do or am I completely misunderstanding things?

First, go to your home directory: cd ~
Then install electron: npm install electron@1.4.15

I think I need to study some very basic tutorials before I even try to install stuff!

@Esinem its a dependency of magicmirror so it should be installed in the magicmirror directory or globally. Try cd ~/MagicMirror and then the install command again

Esinem

Aha! Many thanks. We seem to be getting somewhere now but not out of the woods yet. MM loads, which is a result, and I get a black screen with a little drop-down with options like full screen, properties, session info but no data displayed. Something flashed up fast as it loaded which I think indicated it couldn’t find something. Helper module? I’m not sure it’s relevant as I see some modules don’t have helper files

I had errors relating to electron@1.17.10 so tried installing that but no change.

Here’s my screen: https://photos.app.goo.gl/4Qbew2OasrjvqhWH2 Doh! Just figured out the drop down is to do with VNC not MM.

I ran dev and I can see the line with config.js is highlighted. It tested without syntax errors. I appreciate sample stuff needs localising but should the clone of the sample show something or do I need to make any changes to display anything?

Esinem

Hurrah!! I found a post dated 3 days ago by Lange which solved it:

npm install --unsafe-perm

Thanks for your input.
