      Random question for you:

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

      Magic-Mirror-Module-PIR-Sensor@1.1.0 postinstall /home/pi/MagicMirror/modules/MMM-PIR-Sensor
electron-rebuild -e …/…/node_modules/electron-prebuilt
An unhandled error occurred inside electron-rebuild

      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.

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

              @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 :)

                @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.

                      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.

                            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.

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

                                  @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:

                                    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

                                    Don’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 -v and then npm -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 npm

                                    And 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 -v again 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.

                                      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=50

                                        and 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.json as shown here and reinstall with npm install in 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.
