MMM-PIR-Sensor - White Screen

Medo · Jan 2, 2017, 9:31 AM

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 · Jan 2, 2017, 11:22 AM

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 · Jan 8, 2017, 8:01 PM

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”.

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.
