TypeError: assign to read only property 'exports' of object '#<Object>'

[BotellaA]

I am trying to start a new Electron app using VueJS framework. For that, I created a new project using the vue-cli and copied some files from paraview-glance. The project is almost empty but I get this error:

Uncaught TypeError: Cannot assign to read only property 'exports' of object '#<Object>'
    at Module.eval (webpack-internal:///…les/_is-object.js:5)
    at eval (webpack-internal:///…les/_is-object.js:8)
    at Module../node_modules/vtk.js/node_modules/core-js/modules/_is-object.js (app.js:8014)
    at __webpack_require__ (app.js:767)
    at fn (app.js:130)
    at eval (webpack-internal:///…it-if-required.js:1)

    at __webpack_require__ (app.js:767)
    at fn (app.js:130)
    at eval (webpack-internal:///…xp.constructor.js:2)

I do not understand it. To reproduce the error:

git clone https://github.com/BotellaA/geode.git
cd geode
npm install
npm run electron:serve

Thanks a lot for your help!!

I'm not 100% sure exactly where the issue begins here. This is a result of importing a vtk.js file, but I'm not sure if this is a vue-cli webpack config or something else.

I looked around and found this link: vuejs/vue-cli#2675. Maybe try it to see if it resolves your issue?

Your proposition did not work.
I found this babel.config.js that works, not sure if this is a good idea.

module.exports = {
  ignore: [/\/core-js/],
  sourceType: "unambiguous",
  presets: ["@vue/app"]
};

Hm, we don't use core-js (at least not directly). It might be used by vue-cli, but haven't checked. Glad to know you found a solution.

If you find a better solution or an explanation, feel free to share it 😉
