Cannot add PouchDB in electron

Question

I am using quasar+electron to write a native app through vue.js

Whenever I try to import PouchDB in my electron's preload, I get: Error: module not found: pouchdb/dist/pouchdb

I have installed and tried both PouchDB as mentioned here and pouchdb-browser, but none work:

I have tried adding pouchdb in my preload with the follwoing ways, and NONE does work:

// import PouchDB from 'pouchdb-browser';
// import PouchDB from 'pouchdb';
// import * as PouchDB from 'pouchdb-browser';
import * as PouchDB from 'pouchdb';
// import * as PouchDB from 'pouchdb/dist/pouchdb';
// const PouchDB = require('pouchdb-browser');
// import sampleModule = require('pouchdb');

I have followed the guidelines for TypeScript, like "allowSyntheticDefaultImports": true and $ npm install pouchdb @types/pouchdb but still that doesn't solve the problem :S

Any ideas?
