As per this comment, the deduping seems to be caused by the date-fns module in /date-adapters not having name or version. Simply adding some dummy name to the package.json file fixes this, eg:

(date-adapters/date-fns/package.json)

{
  "main": "./index.js",
  "typings": "./index.d.ts",
  "name": "not-date-fns"
}
