Cannot generate module for [email protected]/dist/ulive.es.js

SyntaxError: unknown: Support for the experimental syntax 'logicalAssignment' isn't currently enabled (31:11):

  29 |     c = {
  30 |       get value() {

     |           ^
  32 |         return s.value

  34 |     },

Add @babel/plugin-proposal-logical-assignment-operators (https://git.io/vAlRe) to the 'plugins' section of your Babel config to enable transformation.

Would it be possible to enable it?
