Typescript version of the config file (dts.config.ts) throws an error when running build

[lukasbals]

Current Behavior

When I use a dts.config.ts (Typescript version of the config file) with the following contents (same as in the example in the readme):

import { defineConfig } from 'dts-cli';

export default defineConfig({
  // This function will run for each entry/format/env combination
  rollup: (config, options) => {
    return config; // always return a config.
  },
});

I get the following error when running npm run build (dts build):

Error: Cannot find module 'dts-cli'

Expected behavior

The build starts.
