Sorry to hear that.

For me it worked with those dependencies fixed.

pi@raspberrypi:~$ npm -v ; node -v
4.1.2
v7.7.1
pi@raspberrypi:~$ cd MagicMirror/
pi@raspberrypi:~/MagicMirror$ cd node_modules/
pi@raspberrypi:~/MagicMirror/node_modules$ npm install electron

> electron@1.6.6 postinstall /home/pi/MagicMirror/node_modules/electron
> node install.js

magicmirror@2.1.1 /home/pi/MagicMirror
└── electron@1.6.6

pi@raspberrypi:~/MagicMirror/node_modules$

Here the thread I’ve been looking last night: https://github.com/electron/electron/issues/9324
User: johannesjo made a fork: https://github.com/johannesjo/electron-prebuilt

But what I did was to downgrade the extract-zip:

pi@raspberrypi:~$ cd MagicMirror/
pi@raspberrypi:~/MagicMirror$ cd node_modules/
pi@raspberrypi:~/MagicMirror/node_modules$ npm uninstall extract-zip
.
.
.
pi@raspberrypi:~/MagicMirror/node_modules$ npm install extract-zip@1.6.0
.
.
.
pi@raspberrypi:~/MagicMirror/node_modules$ npm install electron

As a result of all this:

pi@raspberrypi:~/MagicMirror$ npm install

> magicmirror@2.1.1 install /home/pi/MagicMirror
> cd vendor && npm install

magicmirror-vendors@ /home/pi/MagicMirror/vendor
├── font-awesome@4.7.0
├── moment@2.18.1
├── moment-timezone@0.5.13
└── weathericons@2.1.0


> magicmirror@2.1.1 postinstall /home/pi/MagicMirror
> sh installers/postinstall/postinstall.sh

MagicMirror installation successful!
pi@raspberrypi:~/MagicMirror$

Hope it helps

I’ve checked the thread where everyone reported the issue and right now they are on it.
Good news tho for those without patience. It seems that other module is causing all this trouble: xtract-zip@1.6.1 to 1.6.4 is interfering with post install.

To solve this:

npm uninstall extract-zip
npm install extract-zip@1.6.0
npm install electron

@mitchscobell

my bad, typo there, Corrected now.

I think we have discussed this in two different posts: https://forum.magicmirror.builders/topic/2457/electron-npm-error/22

I ran into some trouble myself after installing the MMM-PIR-Sensor (the whole MM is not starting :D )
Mental Note: Remember to BackUp stable builds!

I don’t see the need of using sudo for npm install.
I’ve tried to replicate your error(took a while to undo the fixes):

npm list

npm ERR! extraneous: gulp-stylelint@3.9.0 /home/pi/MagicMirror/node_modules/gulp-stylelint
npm ERR! extraneous: stylelint@7.8.0 /home/pi/MagicMirror/node_modules/stylelint

npm purge

npm WARN grunt-stylelint@0.8.0 requires a peer of stylelint@^7.8.0 but none was installed.
npm WARN stylelint-config-standard@16.0.0 requires a peer of stylelint@^7.8.0 but none was installed.

npm rebuild
got this: coffee-script@1.10.0 should be installed with -g // npm WARN prefer global jsonlint@1.6.2 should be installed with -g

cd /MagicMirror/node_modules/
npm install  coffee-script@1.10.0 -g
npm install jsonlint@1.6.2 -g
npm install stylelint
npm install colorguard@1.2.0 -g

npm list (again yes)

you will get an error: npm ERR! extraneous: stylelint@7.10.1 /home/pi/MagicMirror/node_modules/stylelint because we instaleld manually.

Give it a try and let us know.

@DeanoAus

You are welcome and glad it works!
