this work for me, add to vue.config.js configureWebpack: { output: { globalObject: 'this', }, },

I ran into similar issues in a worker-loader + webpack-worker-wrapper setup. You can work around it by adding this to your vue.config.js :

module.exports = {
  chainWebpack: config => {
    config.output.globalObject('this')
  }
}

… and doing something like this in your worker.js files :

import workerGlobals from './workerGlobals.js'

and in workerGlobals.js

//Comment the lines you don't need.
global.process = process
window = undefined
