npm start error?

  • Hi,
    I’m using a RPi 0 wireless, I have followed this tutorial step by step: However, when I put in “npm start” I’m getting this message:

    npm ERR! Linux 4.4.50+
    npm ERR! argv "/usr/local/bin/node" "/usr/local/bin/npm" "start"

    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)

    Try updating your versions of node and npm as well

    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 😕

    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/ (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

  • @romain v4.2.1

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

  • Project Sponsor Module Developer

    @longod try npm install --unsafe-perm

  • @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!

  • @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
