Bulma + Vuetify can't access scss variables with Vuejs

I had to merge 2 projects in one. One had Vuetify, and the original had Bulma for stylisation.

When I manage to make vuetify work, bulma got lost in scss apparently (before bulma was working). I try to change the Webpack, sass Loaders.

Bellow my package.json

"dependencies": {
  "bulma": "^0.7.5",
  "core-js": "^3.6.4",
  "vue": "^2.6.11",
  "vue-router": "^3.1.5",
  "vuetify": "^2.2.22",
  "vuex": "^3.1.2"

  "extract-text-webpack-plugin": "^4.0.0-beta.0",
  "style-loader": "^0.21.0",
  "webpack-cli": "^3.0.8"

I tried other solutions here in stackoverflow, but didn’t find one for 2 scss libraries and not sure if is possible.

main.scss
// If imported the css like bellow, it works, but then, I can not edit.
@import '~bulma/css/bulma.css';

// If imported like bellow I got the error.
@import '~bulma/bulma';

What could I’ve been doing wrong?
