babel-node not transpiling lerna imported code

Question

I´m using lerna with some packages:

packages
   - server
   - authenticator
   - graphql

server is my current project and authenticator and graphql are imported modules.

Here is my server package.json:

{
  "name": "@monorepo/server",
  "version": "3.0.0",
  "private": true,
  "scripts": {
    "start": "nodemon --exec \"cd ./src && babel-node server.js",
    "lint": "eslint ."
  },
  "dependencies": {
    "@monorepo/authenticator": "3.0.0",
    "@monorepo/graphql": "3.0.0",
    "babel-cli": "^6.26.0",
    "babel-preset-env": "^1.6.1",
    "babel-preset-react": "^6.24.1",
    "babel-preset-stage-3": "^6.24.1",
    "bcryptjs": "^2.4.3",
    "body-parser": "^1.17.2",
    "connect-mongo": "^2.0.0",
    "crypto": "^1.0.1",
    "express": "^4.15.3",
    "jwt-simple": "^0.5.1",
    "mongoose": "^5.0.10",
    "morgan": "^1.8.2",
    "nodemailer": "^4.6.0",
    "passport": "^0.4.0",
    "passport-jwt": "^4.0.0",
    "path": "^0.12.7",
    "validator": "^9.1.1"
  }
}

My src/server.js file:

import express from "express";

import appGraphQL from "@monorepo/graphql/src";
import * as authenticator from "@monorepo/authenticator";

const app = express();

app.listen(3000, () => {
  console.log(`Find the server at: http://localhost:3000`); 
});

My graphql/src/index.js:

 import graphqlHTTP from "express-graphql";

    ... some stuff here...

My authenticator/src/index.js:

 import passport from "passport";
    import passportJWT from "passport-jwt";
    import jwt from "jwt-simple";
    import bcrypt from "bcryptjs";
    import crypto from "crypto";
    import mongoose from "mongoose";

    ... some stuff here...

When running

$ yarn start
import passport from "passport";
^^^^^^

Can´t understand why is babel-node transpiling the graphql package and is not transpiling the authenticator package.

Is this a bug in babel-node ? What am I missing here ?

PS: Laravel internally use symlinks to modules. I´m using Windows 10.
