Lerna does not support yarn 2 workspace:* url type

Lerna does not seem to support the new workspace:* version schema used in yarn2. This seems really strange to me given that the yarn documentation mentions Lerna immediately after the section in the documentation on workspace:* so I may be missing something here.

Expected Behavior

I would expect Lerna to understand this dependency format and resolve to the local workspace copy of the package.

Current Behavior

Lerna: ERR! Error: unsupported url type “workspace:”: “workspace:*”

Steps to Reproduce (for bugs)

Create a simple repo using yarn 2 with packages a and b

Run

yarn workspace a add b@workspace:*

Run lerna version

Your Environment

Executable	Version
lerna --version	3.20.2
yarn --version	2.0.0-rc.33
node --version	12.16.1

OS	Version
NAME	VERSION
Windows 10	17763

Waiting for this feature too 👍

Until this issue is resolved, would it make sense to remove this text from https://yarnpkg.com/features/workspaces#yarn-workspaces-vs-lerna? It is so far as I can tell factually incorrect.

If there is some sense in which it is correct, maybe there is some improvement to the wording that doesn’t have the same risk of misleading users into thinking some things will work that don’t.

Despite the appearances, the Yarn workspaces and Lerna don’t compete. In fact, Lerna will use Yarn’s workspaces if possible. In a sense, you can see Lerna as a high-level layer on top of the low-level Yarn implementation.
