Vue Typescript component library - Working with Webpack and SASS

I'm currently in the process of building a Vue UI component library for a company and in this process, I'm using webpack as the default bundler. I want to build the whole project into an npm package that then can be distributed via a private git package repository. The package distribution is up and running, but I can't seem to get components exported in the right way so it's possible to use in another project.

Versions for different tools used:

npm: 6.14.4

node: 12.17.0

yarn: 1.22.0

@vue/cli: 4.4.1

tsc: 3.9.5

Project structure is as follows:

public
src
 - assets
  | - css
  |  | - tailwind.css
  | - fonts
  |  | - stylesheet.css
 - component
  | - LbButton
  |  | - LbButton.vue
  |  | - index.ts
  | - Lbtag
  |  | - LbTag.vue
  |  | - index.ts
  | - ...
 - theme
  | - index.ts
  | - Theme.ts
 - typedefs
  | - types.ts
  | - events.ts
  | - model.ts
  | - states.ts
 - views
  | - Home.vue
 - App.vue
 - index.ts
 - main.ts
 - plugin.ts
 - shims-vue.d.ts

const i18n = new VueI18n({

  messages
});

new Vue({
  i18n,
  render: h => h(App)
}).$mount("#app");

If I need to post more files, please don't hesitate to ask. When i bundle all of this up and include it in a project like import { LbButton } from "@livebackend/ui" I get an error that tells me that vue can't find type declarations or module. When i then try to import it from "@livebackend/ui/src" I get another error that tells me vue can't figure out what "@" means. I use "@" to find relative modules within the project.

Is there anyone that have had these problems before ?
