Angular 4 tree shaking with Rollup plugin

I’m trying to use Tree shaking in my application with the Rollup plugin.

When I run node_modules/.bin/rollup -c rollup-config.js I get this error:

[!] Error: ‘Subject’ is not exported by node_modules/rxjs/Subject.js

This is my rollup-config.js file:

import nodeResolve from 'rollup-plugin-node-resolve';
import commonjs from 'rollup-plugin-commonjs';
import uglify from 'rollup-plugin-uglify';

export default {
    input: 'src/main.js',
    output: {
        file: 'src/build.js', // output a single application bundle
        format: 'iife',
    sourceMap: false,
    onwarn: function (warning) {
        // Skip certain warnings

        // should intercept ... but doesn't in some rollup versions
        if (warning.code === 'THIS_IS_UNDEFINED') { return; }

        // console.warn everything else
    plugins: [
        nodeResolve({ jsnext: true, module: true }),
            include: 'node_modules/**',
            include: 'node_modules/rxjs/**',
            include: 'node_modules/ng2-cache-service/**',
            include: 'node_modules/ng2-dragula/**'

I used to have similar errors for the ng2-cache-service and ng2-dragula modules but I solved them by importing those into the commonjs

I can not do the same with rxjs/Subject
