npm start error?

[longod]

Hi,
I’m using a RPi 0 wireless, I have followed this tutorial step by step: https://forum.magicmirror.builders/topic/2075/magicmirror-on-pi-zero-w/2. However, when I put in “npm start” I’m getting this message:

Any help on how to solve this issue would be greatly appreciated! Thanks in advanced!

@longod I don’t own a pi zero but I have few question.

1. Were you on the MagicMirror folder when you did the npm start ?
2. Were you directly on the pi using a usb keyboard (or equivalent) or were you on ssh ?

If you were on the MagicMirror folder and you were directly on the pi I don’t know what the issue could be.
If you wasn’t on the MagicMirror folder npm start won’t work.
If you accessed your pi by ssh you need to use DISPLAY=:0 npm start command instead of npm start because graphical application need to know where they should be open. DISPLAY:0 mean the host machine (your pi)

@longod

Try updating your versions of node and npm as well

@romain

1. Yea I was on the MagicMirror folder when I used npm start
2. I’ve tried npm start on the pi using a keyboard, and I’ve tried through SSH. Got the same error message

@Mykle1
Just tried npm install and it gave out:

npm WARN cannot run in wd @magicmirror2.1.1 cd vendor && npm install (wd=/home/pi/MagicMirror)
npm WARN cannot run in wd @magicmirror2.1.1 sh installers/postinstall/postinstall.sh (wd=/home/pi/MagicMirror)

I then did npm update and that gave out:

/
> electron@1.6.7 postinstall /home/pi/MagicMirror/node_modules/electron
> node install.js

electron@1.6.7 node _modules/electron
>extract-zip@1.6.0 (debug@0.7.4, yauz1@2.4.1, mkdirp@0.5.0, concat-stream@1.5.0)
>electron-download@3.3.0 (semver@5.3.0, home-path@1.0.5, minimist@1.2.0, rc@1.2.1, debug@2.6.4, path-exists@2.1.0, sumchecker@1.3.1, fs-extra@0.30.0, nugget@2.0.1)

afterwards I ran npm start on the pi, and DISPLAY=0: npm start on SHH, and got the same original error messages.

@longod what is your version of node ? node --version

[longod]

@romain v4.2.1

[romain]

@longod I’m using the v7.9.0 . try to install an higher version of node

[strawberry 3.141]

@longod try npm install --unsafe-perm

[longod]

@romain Okay I’ve updated to v7.7.1. I then tried DISPLAY=0: npm start and I got a similar message as before, however there is no longer a ERR! node v4.2.1 message, it skips over that part. Some progress!

[longod]

@strawberry-3.141 I gave that a go and checked npm -v, now its at 4.5.0 and is in the same boat as the node message that I was getting when I try to do DISPLAY=0: npm start. There still is the rest of the npm ERR! messages, just not the npm ERR! node v4.2.1 and npm ERR! npm v2.14.7
