Namespace 'sharp' has no exported member 'SharpInstance'

After upgrading from 0.20 to 0.21 I got the follwoing error:

  [tsl] ERROR in /home/travis/build/zxing-js/library/src/test/core/util/SharpImage.ts(8,32)
        TS2694: Namespace 'sharp' has no exported member 'SharpInstance'.

I’m using sharp as this:

// https://github.com/zxing-js/library/blob/master/src/test/core/util/SharpImage.ts

import * as sharp from 'sharp';

import BitMatrix from '../../../core/common/BitMatrix';

export default class SharpImage {

    public constructor(
        private wrapper: sharp.SharpInstance,
        private buffer: Uint8ClampedArray,
        private width: number,
        private height: number
    ) { }

  // ...
}

How can I get SharpInstance in this new version?

Just for future reference, the SharpInstance interface was renamed to just Sharp.
