Once this step is completed, remove all the node_modules for sass from your project so only compiled Sass files are present in order to rebuild your project from scratch again to ensure a clean compilation

Here are some commands you can use:
"devDependencies": {
    "@vue/cli-plugin-babel": "~4.5.0",
    "@vue/cli-plugin-eslint": "~4.5.0",
    "@vue/cli-service": "~4.5.0",
    "babel-eslint": "^10.1.0",
    "eslint": "^6.7.2",
    "eslint-plugin-vue": "^6.2.2",
