Here is how to fix the infamous Vue error, which you may need while experimenting and learning with Vue, not in production.
Here is your ESlint configuration in package.json :
"eslintConfig": {
"root": true,
"env": {
"node": true
},
"extends": [
"plugin:vue/essential",
"eslint:recommended"
],
"parserOptions": {
"parser": "babel-eslint"
},
"rules": {
"vue/no-unused-components": "off"
}
},
