Unable to install dependencies, NPM install not working

[cpramhofer]

Hi All,

after my holiday i gave the thing another chance with a fresh install:

Raspbian Jessie with Pixel
2016-09-23 (is this the problem???)

npm WARN grunt-yamllint@0.2.0 requires a peer of grunt@~0.4.0 but none was installed.

or is it the problem that the installer is still using eletron-prebuild instead of electron??

[tajno]

Did you tried the followed:

npm install npm@latest -g
npm install -g grunt
npm install -g electron

[cpramhofer]

IT WORKS!!

thanks @tajno for the hint!

My Steps to working MM:

• Fresh Card with latest Version of Raspian (PIXEL)
• [running the installer Script]
• MMM DID NOT WORK AT THIS STAGE
• running
  sudo npm install npm@latest -g
  sudo npm install -g grunt
  sudo npm install -g electron
• manual install of MMM (git clone / sudo npm install / npm start)

kind regards
Christoph

here is what worked for me
git reset --hard and then git pull && npm install

@sharkbyte yeh, if you use my upgrade script it handles all that. Reset hard is, in my opinion, a bad thing to do, unless you KNOW why you are doing it.
