CRA fails with npm error in yarn project using "workspace:" dependencies

[hwinkler]

Describe the bug

In a yarn project, when CRA gets to the "Installing template dependencies using npm..." part, it uses, well, npm.

npm seems unable to understand dependencies of the form

    "module": "workspace:*"

in package.json.

yarn dlx create-react-app appname  #same problem using npx

fails when run in a project with such workspace:* dependencies.

In a multi-workspace project, CRA seems to process all the peer-level workspaces (via npm despite the fact that it is running in a yarn project). npm encounters dependencies of that workspace:* form, and errors out with

npm ERR! code EUNSUPPORTEDPROTOCOL
npm ERR! Unsupported URL Type "workspace:": workspace:*

Environment

$ npx create-react-app --info

Steps to reproduce

File hierarchy:

package.json
workspace1
    package.json
workspace2
    package.json

top-level package.json:

{
  "name": "cra-yarn",
  "packageManager": "yarn@4.2.2",
  "workspaces": [
    "workspace1",
    "workspace2",
    "cra"
  ]
}

workspace1/package.json:

{
  "name": "workspace1",
  "packageManager": "yarn@4.2.2",
  "dependencies": {
    "workspace2": "workspace:*"
  }
}

workspace2/package.json:

{
  "name": "workspace2",
  "packageManager": "yarn@4.2.2"
}

Run yarn in the top level directory, then execute:

npx create-react-app cra

Expected behavior

Create an app in the cra subdirectory with no errors.

Actual behavior

$ npx create-react-app cra   # similarly for yarn dlx create-react-app cra

Creating a new React app in /path/to/tmp/cra-yarn/cra.

Installing packages. This might take a couple of minutes.
Installing react, react-dom, and react-scripts with cra-template...

npm ERR! code EUNSUPPORTEDPROTOCOL
npm ERR! Unsupported URL Type "workspace:": workspace:*

When you run using yarn dlx, you'll see:

Installing template dependencies using npm...
npm ERR! code EUNSUPPORTEDPROTOCOL
npm ERR! Unsupported URL Type "workspace:": workspace:*

Note that the package.json files declare that they use yarn. So it would make sense for the "nstalling template dependencies" action also to use yarn?
