Rpi 3B+, can't install

[epi]

Still doesn’t work for me.
What I did is

1. Install fresh RASPBIAN STRETCH WITH DESKTOP
2. After install, configure wifi credentials and enable SSH access
3. Connect via SSH and proceed with

curl -sL https://deb.nodesource.com/setup_10.x | sudo -E bash -

sudo apt install -y nodejs

node -v

(got answer “v10.10.0”)

git clone https://github.com/MichMich/MagicMirror

cd MagicMirror/

npm install && npm start

[epi]

any clue what to do next?

Not sure this will help but you could try npm install -g electron within your MagicMirror directory.

If that doesn’t work, try npm install electron@2.0.0 inside your MM directory.

Issue found, everything works now.
Problem was my SD card, it, is (becomes) corrupt at some point.

That’s why I run mine from a cheap SSD (Kingston A400, 120GB iirc). Much faster and no risk of corrupting it. I paid 27€ for my SSD. At this price I think it is worth considering buying one.

Please try the following

sudo apt-get remove nodejs nodejs-legacy nodered

after that

curl -sL https://deb.nodesource.com/setup_8.x | sudo -E bash -
sudo apt-get install -y nodejs
sudo npm install -g npm@latest

after that enter in the repository with

cd MagicMirror

If have not install MM, use this from github

 bash -c "$(curl -sL https://raw.githubusercontent.com/MichMich/MagicMirror/master/installers/raspberry.sh)"

then install and run the app with

npm install && npm start

This method worked for me.
