Hi,

I’m using the calender to show the next public holidays by including a public calendar:

               {
                    module: "calendar",
                    header: "Feiertage",
                    position: "top_left",
                    config: {
                            calendars: [
                                    {
                                            url: "http://www.ifeiertage.de/by-.ics"
                                    }
                            ]
                    }
            },

The appointments that are more than 1 Month away are just shown as “in %s Mon.”, see attached image.

Maybe the plural of “Mon.” has to be explicitly specified (I’m using language: de ) but I don’t know how.
Can you reproduce (and maybe fix) this issue?

@Hawking Thanks for all your help and comments, I’ve managed to get it up and running now!

No problem.

Now I just need to get the whitelist sorted :grimacing:

This worked fine for me, I just added the IP of my regular PC (e.g 192.168.2.185) to the list in the config file so that it looked like

ipWhitelist: ["192.168.2.185", "127.0.0.1", "::ffff:127.0.0.1", "::1"],

If I then typed the ip:port (the port is also defined in the MM config, default is 8080) of my raspi (e.g.

http://192.168.2.170:8080/

) in the browser bar of my regular PC I could see the page also on my regular PC (took 1-2 seconds to load).
If this does not work for you, just open a new thread and provide details.

Confirmed.
And already many thanks for all your work. I think you can be proud that this results in “your” mirrors spreading from Norway to Spain

I now did a installation on a fresh image and used node version 6.6.1 which automatically includes npm 3.10.8. So instead of

sudo wget http://node-arm.herokuapp.com/node_latest_armhf.deb
sudo dpkg -i node_latest_armhf.deb
sudo apt-get install npm

I did

wget -O - https://raw.githubusercontent.com/sdesalas/node-pi-zero/master/install-node-v6.9.1.sh | bash

Then I got later on no warnings about to old or insecure version any more but just

npm WARN prefer global coffee-script@1.10.0 should be installed with -g
npm WARN prefer global jsonlint@1.6.2 should be installed with -g
npm WARN prefer global colorguard@1.2.0 should be installed with -g

> electron-chromedriver@1.6.0 install /home/hawking/MagicMirror/node_modules/electron-chromedriver
> node ./download-chromedriver.js


> electron@1.6.5 postinstall /home/hawking/MagicMirror/node_modules/electron
> node install.js

npm WARN lifecycle magicmirror@2.1.1~install: cannot run in wd %s %s (wd=%s) magicmirror@2.1.1 cd vendor && npm install /home/hawking/MagicMirror
npm WARN lifecycle magicmirror@2.1.1~postinstall: cannot run in wd %s %s (wd=%s) magicmirror@2.1.1 sh installers/postinstall/postinstall.sh /home/hawking/MagicMirror

(in this installation I did not use the pi user, but I had the same problem when I used the default pi user).

If one knows the solution for the blank screen it is obvious that this is a strong hint that one should run

cd ~/MagicMirror/vendor/ && npm install 
cd ~/MagicMirror/ && sh installers/postinstall/postinstall.sh 

(the later at the moment just prints a success message and is therefore not really needed)
I don’t know why these commands did not work automatically, maybe an issue with some directories that are not set (I assume in the error instead of %s the directory should be displayed).

I could fix my issue with the blank screen by simply doing

cd ~/MagicMirror/vendor
npm install

Then it seem to work (even with the node v 4.2.1). Nevertheless I will try to update to a more recent version of node, just to avoid other problems that are likely to exist in this old node version.

@Hawking said in MagicMirror on Pi Zero W:

/home/pi/MagicMirror/node_modules/moment

it should look like this /home/pi/MagicMirror/vendor/node_modules/moment do you have a package.json file in /home/pi/MagicMirror/vendor?

I have a directory /home/pi/MagicMirror/vendor containing
package.json and vendor.js but noting more.

I now used npn version 2.14.7 (checked by npm -version) to

cd ~/MagicMirror/vendor
npm install

This gave

npm WARN package.json magicmirror-vendors@ No README data
font-awesome@4.7.0 node_modules/font-awesome
moment-timezone@0.5.13 node_modules/moment-timezone
weathericons@2.1.0 node_modules/weathericons
moment@2.18.1 node_modules/moment

and the folder /home/pi/MagicMirror/vendor/node_modules/moment that you mentioned before was created.
I then rebootet (not sure if necessary) and it seems to work (I see the date and time, holidays,quote…). I’ll now set everything up but it looks way better then before.
So thanks a lot for your help!! I hope that your fix also works for the other people who have the same problem.

Just to understand the fix a bit better:
Is there a reason that one seem to have to do run
sudo npm install once in /home/pi/MagicMirror/ (this is already included in the initial post) and once npm install in /home/pi/MagicMirror/vendor/? (this is not mentioned in the initial post and also not directly done by the standard installer (that does not work for the pi-Zero) located in /home/pi/MagicMirror/installers/raspberry.sh (at least I don’t see it therein).

@strawberry-3.141 said in MagicMirror on Pi Zero W:

@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

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?

@Mitchfarino said in MagicMirror on Pi Zero W:

@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

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).

@Mitchfarino said in MagicMirror on Pi Zero W:

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

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.

@Iseknutz said in MagicMirror on Pi Zero W:

Did you solve the problem? Maybe the other modules use any functions that the Pi Zero don’t understand…?

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.

@Mitchfarino
I’m using the Zero W but have exactly the same problem (just a blank screen).
I found that the clock module gives me frequent errors in /var/log/daemon.log (complaining about missing “moment”, similar to my post here) do you get these as well?
However also most of the other modules don’t work for me. What worked for me was to remove all default modules from the config file and just use the very simple “halloworld” module

{
                module: "helloworld",
                position: "top_bar",
                config: {
                        text: "Hello world!"
                }
  }

Then I got at least some text on my empty screen and knew that in principle MM was working. I also could get the externally installed MMM-Globe and MMM-SystemStats running.
But of course it would be good to get the default modules running…

I also got this empty page if I requested the website from my regular PC using Firefox, so I think it is not related to a shortcoming of the midori browser.

I tried Jessie and Jessie Light and different versions of node.js/npm. During the npm install step I get several errors/warnings, however some people said that some of these are normal…

@bmarofsky
I’m also trying to install Magic Mirror on a Pi Zero W.

I think one reason for the problems might be that as far as I can tell

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

got me node v4.2.1 which is quite outdated (the regular installer of MM2 updates nodes if the version of node is below 5.1.0).
I therefore tried to install a more recent version of node following the commands here
https://github.com/sdesalas/node-pi-zero
However, the compilation of Magic Mirror worked neither with node 7.7.1 nor with node 6.9.1.

Before I go into details, did anybody got Magic Mirror working on Raspberry Pi Zero W?
Which node version (and npm version) did you use and how you he install it? Which browser did you use (I read that Midori has some problems)?
