I think the issue is from that first unable to install dependencies issue. Maybe the electron-v1.3.8-linux-arm.zip is in /.electron folder was in the dependencies that were not installed causing npm install to have issues

Im on a pi 2 B

Could that be related to the npm install issue?

I re-installed magic mirror and got this above the unable to install dependencies error

Unable to install dependencies!

Weird, I cannot find a solution to this, I have updated NPM and NodeJS, but not of any use

When I installed MM2 it gave me an error saying “unable to install dependencies!” Then when I ran NPM install it gave me a list of errors.
