Module not found: Error: Can't resolve 'vue-property-decorator' ...

[Pazulay]

I have a Vue 2 project that uses Webpack and typescript with class component syntax. The class component syntax is made available with the 'av-ts' plugin. I am trying to replace av-ts with vue-class-component/vue-property-decorator but my webpack bundler is throwing this error after I adjusted one of the components.

ERROR in ./src/components/example-component/example.component.ts
