          so rn i did the install in the /home/pi/node_modules and i put this in my MMM-Swipe node_helper.js file. (var usonic = require('mmm-usonic'); )

          So then when i run the MagicMirror using npm start these errors show up

            @sgarg15 said in MMM-usonic Problems:

            so rn i did the install in the /home/pi/node_modules

            what install?

            MMM_Swipe (https://github.com/mochman/MMM-Swipe)

            already lists that dependency in package.json

              "dependencies": {
                "math-statistics": "latest",
                "mmm-usonic": "latest",
                "mmm-gpio": "latest"
              },
            

            and lists that file in node_helper.js

            const usonic = require('mmm-usonic');
            

            the install instructions say

            1. Navigate into your MagicMirror's modules folder and execute git clone https://github.com/mochman/MMM-Swipe.git. A new folder labeled MMM-Swipe will appear, cd into it.
            
            2 Execute npm install to install the dependencies
            

            if u are adding a library to a module, then in the module folder

            /home/pi/MagicMirror/modules/module_name   (MMM-Swipe in this case)
            

            you would do

            npm install --save mmm-usonic
            

            if all of that is ok, then sometimes a module ships a library that is built on a specific level of electron,
            and our is different…
            so do

            cd ~/MagicMirror
            npm install electron-rebuild
            node_modules/.bin/electron-rebuild
            

            to rebuild the used libraries to match the installed electron version

                    @sdetweil that module (mmm-usonic) is not for magic mirror, but a library for a potential module to use to talk to the hardware…

                    sadly has same labeling and same verbiage (module)

                    he wrote MMM-Swipe, which uses his library (mmm-usonic)

                      @sgarg15 to fix the electron rebuild problem,

                      the package.json file in MMM-Swipe and change

                      this

                          "postinstall": "node_modules/.bin/electron-rebuild -e ../../node_modules/electron-prebuilt"
                      

                      to this

                          "postinstall": "node_modules/.bin/electron-rebuild"

                        @sdetweil So the install worked properly but then when i ran sudo npm start it gave this error

                        [1580:0329/130746.224199:FATAL:electron_main_delegate.cc(211)] Running as root without --no-sandbox is not supported. See https://crbug.com/638180.
                        

                        Any idea what that means?
