MagicMirror on Pi Zero W

[Iseknutz]

@Hawking @Mitchfarino
I have the same problem too. I have set up the MM2 on Pi Zero W, everything looks good, but only the modules “helloworld” and “alert” are working. If I try to use the clock module I got a blank, black screen.
Did you solve the problem? Maybe the other modules use any functions that the Pi Zero don’t understand…?

Wish I found this earlier! Spent a few days trying to get it running myself using docker but failed at every turn.

I will give this a run through later today and report back my findings.

I have same problem, too. Any idea of solution?

No, I didn’t solve the problem yet.
I found out that the working modules (helloworld and alert) don’t use the “moment” js library but the modules that result in a blank screen (calendar, clock, compliments, newsfeed and weatherforcast) do. As the error in my /var/log/daemon also contains “ReferenceError: Can’t find variable: moment” I think it is likely that something went wrong in installation of (the moment.js library of) node. And indeed, the installation with

sudo npm install

gave some warnings and errors in my case. As only the Pi Zeros seem to be concerned it must be something due to our “special” installation. The Pi Zero needs a special (ARM) node variant. The version one gets via

sudo wget http://node-arm.herokuapp.com/node_latest_armhf.deb
sudo dpkg -i node_latest_armhf.deb

is quite old (version 4.2.1; the regular installer of MM2 updates nodes to version 6 if the version of node is below 5.1.0 and in an other thread somebody reported that version 7 is working for a regular Pi as well) However, I also tried to use version 6 and 7, but the result was still a blank screen.
I also get this blank screen if I access the provided data via network using Firefox of a regular PC, so I think it is not related to some issues with the midori browser.

But I’m not not at all an expert in this issue, so I might have done something wrong or it could be an other reason (the working modules are also in other ways simpler than the other ones). I would be happy if somebody could tell us how to solve this issue.

@Hawking you should check if moment weas installed properly it sits in the vendor directory in node_modules, if it isnt there run npm install in the vendor directory

@Hawking

I saw errors stating that MM requires a higher version of node, but I couldn’t figure out how to do it.

Could you provide the command you used? Then I’ll try it on mine too and will feed back

I am getting an issue with sudo npm install getting the following error.

npm WARN cannot run in wd magicmirror@2.1.1 cd vendor && npm install (wd=/home/pi/MagicMirror)
npm WARN cannot run in wd magicmirror@2.1.1 sh installers/postinstall/postinstall.sh (wd=/home/pi/MagicMirror)

@McSorley try npm install --unsafe-perm

I think if someone can get this up and running, they should host the image somewhere for people to download.

Don’t load any modules, just go with the default.

Then people can install the ones that they need.

With “vendor directory” you refer to “~/MagicMirror”?
I have a folder
/home/pi/MagicMirror/node_modules/moment with several files (including moment.js) and subfolders. Is this enough indication for a proper installation or should I check other details?

Yes, I got the same error/warnings, that’s why I tried to use a more recent version of node. I used the scripts available here
https://github.com/sdesalas/node-pi-zero
I tested it for v6 (don’t remember which subversion) and v7.7.1. Both was without success (no error/warning about old node version, instead other issues and finally still a blank screen). But maybe I made something wrong. Please try your self and let us know about the results (and post the error you get, I don’t remember them in detail).

I would strongly prefer to know the commands that worked. An image is a huge file that gets outdated (replacement of jessie…), has to be stored on some external server (the free one are usually slow…) The commands on the other hand are hopefully only a small modification of the tutorial writen above, can easily be used and even adapted more easy.
