MMM-PIR-Sensor - White Screen
- 
 @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@2.1.0 start /home/pi/MagicMirror 
 electron js/electron.js “dev”

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

 Launching application.

 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 installedDon’t worry about this one. The log file format is [process] [debug level] [error message]. In this case, “warn” is the level of severity of the message. If it said “err” then it would require your attention. I suspect your nodejs version is out of date. Try running this command: nodejs -vand thennpm -v. It should spit out the version of node and NPM you’re using. Personally, I’m on v7.4.0 and v4.0.5 respectively. If you’re running a few versions behind, you may wish to run these commands from your home folder:curl -sL https://deb.nodesource.com/setup_7x | sudo -E bash - sudo apt-get install -y nodejs sudo npm install -g npm sudo npm install -g npmAnd yes, you may have to run that last command twice. For some reason, NPM sometimes requires a double-tap to update itself. Thank you, StackExchange. Run nodejs -vagain and verify that your node version is up to snuff.

 Hey there, thank you for the suggestion. updated both nodejs and npm to 7.4.0 and 4.0.5. I think removed the MMM-PIR-Sensor folder, grabbed it again from github, and then tried to run npm install on it, and the install failed again. An unhandled error occurred inside electron-rebuild 
 Unable to find electron-prebuilt’s version number, either install it or specify an explicit version

 at startup (bootstrap_node.js:139:9)I tried running the rebuild with my electron version number (1.5.7) but still no luck. Any thoughts on what else I could try? I am drawing a blank here, unfortunately. 
- 
 @Them-Russians i also thought i have a higher electron-version. but i tried npm rebuild --runtime=electron --target=1.4.3 --disturl=https://atom.io/download/atom-shell --abi=50and it worked for me. 
- 
 @Them-Russians I think you definitely need to rebuild electron. I can’t see what else is causing the issue. Try with different electron version numbers. Otherwise I’m all out of ideas. Sorry! 
- 
 @Them-Russians Try changing line 24 in package.jsonas shown here and reinstall withnpm installin the module folder. Does that help?Also: Please continue discussion about install issues here. There is already info on how it can be solved. For other problems with the PIR-Sensor Module please open a new thread in the modeul troubleshooting section.

 Thanx a Million, Bro’ !! The step-by-step did it for me! I couldn’t understand that everybody’s was working so cool and mine dis diddly-squat?!? So removing the module and reinstalling was the answer. No idea what went wrong first time round; Just grateful it is now working as expected. Thanx for your great post!!

 I’m glad to hear that! :-D

 @Medo Solved it for me, thanks!
