export Metric was not found in @superset-ui/core

[NicolasNeubauer]

after running

npm i @superset-ui/core
npm i @superset-ui/plugin-chart-echarts

and including the library through

import {
  EchartsTimeseriesChartPlugin,
  EchartsPieChartPlugin
} from '@superset-ui/plugin-chart-echarts'

new EchartsTimeseriesChartPlugin().configure({ key: 'echarts-ts' }).register()
new EchartsPieChartPlugin().configure({ key: 'echarts-pie' }).register()

I get the following error:

Failed to compile.

./node_modules/@superset-ui/chart-controls/esm/types.js
Attempted import error: 'Metric' is not exported from '@superset-ui/core'.

This is also reported in an SO question (by someone else):

How do I get this to work?
