JSForce Integration with Angular Failed to compile. export 'ConnectionConfig' was not found in './connection'

Question

I have recently started using angular and I want to do an integration with jsforce. My problem is that when I try to call some jsforce method the following message appears ->

Failed to compile.

./node_modules/jsforce/browser/core.js 14:0-185 "export 'ConnectionConfig' was not found in './connection'

Image of above error

I tried to include in the class

import jsforce from 'jsforce';
import { config } from 'process';

But it still does not work. I hope you can help me.

Thank you very much.
