.parcelrc fails to extend @parcel/config-default - cannot find module

🐛 bug report

I’m getting started with parcel in a brand new project with only a few files. I want to use tsc as the default Typescript compiler so I’m following instructions posted here: https://v2.parceljs.org/languages/typescript/#typescript’s-tsc

Once I added the .pacelrc parcel no longer complies. It now fails with the following error:

Error: Cannot find module '@parcel/config-default' from 'X:\projects\boomerang'
    at X:\projects\boomerang\boomerang-website\node_modules\resolve\lib\async.js:116:35
    at processDirs (X:\projects\boomerang\boomerang-website\node_modules\resolve\lib\async.js:269:39)
    at isdir (X:\projects\boomerang\boomerang-website\node_modules\resolve\lib\async.js:276:32)
    at isDirectory (X:\projects\boomerang\boomerang-website\node_modules\@parcel\utils\lib\resolve.js:56:9) {
  code: 'MODULE_NOT_FOUND'
}

🎛 Configuration (.babelrc, package.json, cli command)

.parcelrc

{
  "extends": ["@parcel/config-default"],
  "transformers": {
    "*.{ts,tsx}": ["@parcel/transformer-typescript-tsc"]
  }
}

.package.json

{
  "name": "boomerang-website",
  "version": "1.0.0",
  "scripts": {
    "prestart": "npm run clean",
    "start": "npx parcel ./src/*.html",
    "clean": "npx rimraf ./dist",
    "prebuild": "npm run clean",
    "build": "npx parcel build ./src/*.html",
    "predeploy": "npm run build",
    "deploy": "sls deploy -v"
  },
  "devDependencies": {
    "parcel": "^2.0.0-beta.1",
    "rimraf": "^3.0.2"
  },
  "dependencies": {
    "serverless-cloudfront-invalidate": "^1.5.0",
    "serverless-s3-sync": "^1.15.0"
  }
}

🤔 Expected Behavior

Should resolve @parcel/config-default, the package exists.

😯 Current Behavior

Error: Cannot find module '@parcel/config-default' from 'X:\projects\boomerang'

Make sure that parcel, @parcel/config-default and @parcel/validator-typescript are all on the same (or latest) nightly version.

But aside from that, should it be necessary to explicitly import @parcel/config-default? If so, shouldn’t that be in the documentation? I am willing to add it if that is the correct solution.

Yes, for example Yarn PnP would throw an error if you don’t list it in the dependencies. But I’m not quite sure how to put that into the docs without adding a note to every blue “example” block with a .parcelrc (or maybe that’s fine?)

You should install @parcel/config-default and @parcel/transformer-typescript-tsc as dependencies
