storybook: SB 5.2 Typescript build fail - (Addon-knobs)

I’m running into a couple of issues when updating to 5.2.

Both errors seem to be caused by the addon knobs package.

1. Complains about a missing dep (manually installing @types/react-color fixes this one)

ERROR in [at-loader] ./node_modules/@storybook/addon-knobs/dist/components/types/Color.d.ts:3:29 
    TS7016: Could not find a declaration file for module 'react-color'. '/Users/sami/Apps/components/node_modules/react-color/lib/index.js' implicitly has an 'any' type.
  Try `npm install @types/react-color` if it exists or add a new declaration (.d.ts) file containing `declare module 'react-color';`

1. Second complains about a missing export

ERROR in [at-loader] ./node_modules/@types/storybook__addon-knobs/index.d.ts:13:10 
    TS2305: Module '"../../../../../../../Users/sami/Apps/components/node_modules/@storybook/react/dist/client"' has no exported member 'RenderFunction'.
