@bibi can you post your whole config file?

Everything with at least one tab indent is treated as code and highlighted. ;)

bibi

@yawns thx! :))

strawberry 3.141

@bibi you forgot to close the config section in the newsfeed module, add } after showPublishDate: true and you should be fine

bibi

@strawberry-3.141 yeah! thx a lot. at least i can see this white screen now :p :))) have to figure out how to solve this… Only if it’s realllllly really obvious for you/someone, i post my log file. (sorry to ask so much) otherwise not prob, i will reinstall the PIR module…

Ok the problem it’s solved! except the screen is turning on and off in a very strange way… have to figure out why.

For those you would get the same issue as me, what i did after fixing my config file was:

sudo apt-get update & upgrade & reboot,
go in MMM-PIR-Sensor folder in modules folder and run npm install there
3.sudo reboot
cheers

Also had the “white screen” problem. I installed a complete new Raspian (with PIXEL), a new MagicMirror - including node.js in version 7.3.0
As soon as i tried to get the MMM-Pir-Sensor working, it failed (with an white screen). Heres, how i solved my problem.

At first: Theres no need to downgrade the node (i tried this too, and had no luck)

I figured out, that my problem was an MMM-PIR-Sensor installation error i did not recognized at the beginning. When i tried “npm install” i got something like this (an error):

"gyp WARN EACCES user “root” does not have permission to access the dev dir “/root/.node-gyp/5.12.0”

I figured out, that there are two ways of solving this:

CHOWN the directory the install procedure tries to install
use “npm install --unsafe-perm”

Im aware that option two is not the “elegant” way, but it solved my problem (and i did not have to change directory permissions).

I removed all files and git the files again (like described some lines above from banglee) and then just use “npm install --unsafe-perm”

The “–unsafe-perm” option was the key to my problem…

Hi @Medo ,
I have gotten the white screen problem as well and my raspberry pi configuration is similar to yours ( running on PIXEL with the latest nodejs).

However, upon using option 2 from your solution. I have obtained this error :

@zichao92

First things that come to my mind:

maybe a “sudo” is missing? Like sudo npm install --unsafe-perm?
are you executing this from the MMM-PIR-Sensor directory ?

zichao92

Hi @Medo, Thanks for the reply.
1.) I tried this method and it gives an output of the following error.

Yea it’s in the file directory ( MagicMirror/modules/MMM-PIR_Sensor )

@zichao92
What i also did, was a complete reinstall of the PIR-Sensor

I followed the steps, “Banglee” described some lines above:

ok so lets go step by step:
cd ~/MagicMirror/modules/

now we will remove the PIR folder:
rm -rf MMM-PIR-Sensor

and from here, we’re going to reinstall the MMM-PIR-Sensor modul:

git clone https://github.com/paviro/MMM-PIR-Sensor.git
cd MMM-PIR-Sensor

run the following cmd here:
npm install and wait, this can take a few minutes.

Now you’ll have to add pi to gpio
sudo useradd -g pi gpio

and reboot your Raspi:
sudo reboot

Sorry, no further ideas so far (maybe you can open a PIR-Sensor troubleshooting thread)?

Hi @Medo ,
I managed to get it working in an ugly way. Doesnt matter, it works. Thanks for your help!

jwhittaker

I’m having nothing but trouble with this. I’ve tried all the tips on here but still get a white screen.

@zichao92 What was the ugly way and how did you manage to get it working please?

This is the error I get:

Hi @jwhittaker ,
Previously i had a working node_modules that Ive installed through npm install ( Cant rmb how i got it but i managed to create a back up copy of it). Subsequently when I tried to use npm install on a new raspberry pi, it didnt work as intended.

What i did was instead of using npm install, I bypassed it by inserting the node_module that i previously salvaged and it worked for some reasons.

Random question for you:

when i try to do an “npm install” in the “MMM-PIR-Sensor” folder, i get the following error:

Any idea what could cause this? I suspect my white screen is because the install failed.

I have tried removing the “MMM-PIR-Folder” from my directory and running the clone command from github again to start fresh, but still face this issue.

Similar problem to @Them-Russians when running npm install. Then after starting MM using pm2 I get a white screen. Checking the pm2 error logs I see the following error with a module version mismatch: “Expected 50, got 49”.

 0|mm       | App threw an error during load
 0|mm       | Error: Module version mismatch. Expected 50, got 49.

Tried @James solution using npm rebuild but changed the version parameter to 50. Still no luck.

  npm rebuild --runtime=electron --target=1.3.4 --disturl=https://atom.io/download/atom-shell --abi=50

Any help would be much appreciated before I reformat my sd card and start from scratch.

@bungee09
npm list and look for electron to find the right version. Then rerun the rebuild command with replaced version number

@yawns
Works a treat. Thanks!

@bungee09 Did you get the npm install to work on the “MMM-PIR-Sensor” directory? Or did you just run the npm list to get the version of electron and then run npm rebuild --runtime=electron --target=1.3.4 --disturl=https://atom.io/download/atom-shell --abi=50 with the right version?

Which directory were you in when you ran the rebuild?

Sorry - i’m at work now, so dont have the Pi with me, but have been having issues with this for a week now, so i’m really hoping that this works for me :)
