I work on project in JS for Raspberry Pi controller, but I got an error when I started the Node app.js

Warning: epoll is built for Linux and not intended for usage on Windows_NT.internal/fs/utils.js:314 throw err;

Error: ENOENT: no such file or directory, open '/sys/class/gpio/export' errno: -4058, syscall: 'open', code: 'ENOENT', path: '/sys/class/gpio/export'
