MMM-PIR-Sensor - White Screen

bungee09

@Them-Russians - I feel your frustration! I spent a good few hours debugging this after installing and testing my PIR sensor. This is what eventually worked for me:

I ran all the commands in the MMM-PIR-Sensor Directory.

 cd ~/MagicMirror/modules/MMM-PIR-Sensor
 npm list

I found the electron version number to be “1.4.3” so updated target to 1.4.3. Also, updated abi to 50 in the following command as this was the expected value from the error message in pm2 logs.

 npm rebuild --runtime=electron --target=1.4.3 --disturl=https://atom.io/download/atom-shell --abi=50

As soon as the rebuild was complete…

 cd
 pm2 restart mm

… to restart MagicMirror in pm2.

I also found this link which described the same fix.

Good luck!

@bungee09 Did your rebuild work successfuly? I got an error saying that i needed to have the latest versions of node.js and npm installed.

I believe I have node version 6.9.4. Is that what you were using?

After all this, i thought maybe i jacked up something, so i cleared out and reformatted the micro SD card. I reinstalled NOOBS and then got the Magic Mirror. Created the config.js file and ran the mirror without issue. Immediately after that, i cloned the PIR module and tried to run an “npm install” which failed, and so did the rebuild :(

@Them-Russians The rebuild was successful for me using exactly the method I described above. I don’t have my pi with me currently but I only installed node for the first time last week so I definitely don’t have an old version. I can check the exact version number when I get home for you.

@Them-Russians
BTW? Did you install node in the main MagicMirror directory first before installing dependencies in the MMM-PIR-Sensor directory?

 cd ~/MagicMirror
 npm install

@bungee09 I did not do that install in the Magic Mirror folder. I ran the “curl” command from the github site for the MagicMirror, set up config.js, and then immediately got the PIR module.

Do you think i could run the npm install on the MagicMirror folder now, and try again with the rebuild, or would i have to clear my SD card and reinstall everything and start from scratch?

Yes, running npm install now will work and it is required.

@Them-Russians
npm install in the main MM directory. Then npm install in the PIR sensor directory to install dependencies. If it fails then npm rebuild as above using the correct electron version number and abi.

Them Russians

@bungee09 The main MagicMirror directory, or the module directory within MagicMirror?

bungee09

@Them-Russians In the main directory

 cd ~/MagicMirror/
 npm install && npm start

@bungee09 @yawns When i ran the “npm install” in the MM directory, i got this error:

npm warn grunt-yamllint@0.2.0 requires a peer of grunt@~0.4.0 but none was installed

I googled the error and it looks like it shouldnt be an issue, but when i tried doing an install in the PIR directory (it failed), so did the rebuild with the updated electron version number (mine was 1.5.6).

I got the same error when trying to run the rebuild

Failed at the epoll@0.1.20 install script ‘node-gyp rebuild’
Make sure you have the latest version of node.js and npm installed.

Sorry for all the posts on here, but do you have any thoughts? I update node.js and npm to the most recent versions, so i dont think that what is broken for me :(

When i try to run the mirror, here is the error i get before the white screen:

MagicMirror will not quit, but it might be a good idea to check why this happened. Maybe no internet connection?
