vue-loader was used without the corresponding plugin

Trying to do the Single File Component section, and I'm getting this error and I try to do npm run build:

ERROR in ./src/components/Hello.vue Module Error (from ./node_modules/vue-loader/lib/index.js): vue-loader was used without the corresponding plugin. Make sure to include VueLoaderPlugin in your webpack config. @ ./src/index.ts 3:0-52 9:24-38

Sorry if I missed anything obvious, I'm new to web development.
