@RaphaelOtter install the bitvise or winscp clients on windows and enable ssh on the.pi.

then you can edit from your PC and copy files back and forth and execute commands in the ssh window.

I never edit on the pi anymore

@sdetweil I was in the MMM-LAMetro directory. I used the “node install” command from the readme. Forgot the correct command was “npm install”. No issues once I used that command.

@jonspraggins please use the upgrade script here

That worked, thanks!

Reason: Downloding electron takes for ages as the download was below 1kb/s.
Solution: Executing the following command using a faster chinese mirror:

ELECTRON_MIRROR=http://npm.taobao.org/mirrors/electron/ npm install --prefix ~/MagicMirror electron --save-dev

See them more like warnings to the developers. ;) As long as it starts and runs, it runs.

With the help of another User on Github we found out what was causing the error!
It was the sudo, that I mistakenly used to execute the script. Running the install as pi was the solution.

Hope this will help someone with the same problem. :)

You are welcome. I guess you will need to find out on your own if the laptop fullfills your requirements. Power consumption is one aspect, another is loudness and heat due to fans in your laptop.
