Migrating a Yarn workspace from a traditional Angular CLI workspace to an Nx fails

Current Behavior

When trying to migrate a Yarn workspace from a traditional Angular CLI workspace to an Nx workspace, it fails with the following error:

Installing packages for tooling via yarn.
An unhandled exception occurred: error Running this command will add the dependency to the workspace root rather than the workspace itself, which might not be what you want - if you really meant it, make it explicit by running this command again with the -W flag (or --ignore-workspace-root-check).
Package install failed, see above.

Expected Behavior

I expect to be able to migrate my traditional Angular CLI workspace to Nx even if I am using Yarn workspaces.

Steps to Reproduce

Generate a new Angular CLI workspace

ng new my-app --defaults --package-manager=yarn

Make it a Yarn workspace

Add "workspaces": [] to the package.json file.

Try migrating to an Nx workspace

ng add @nrwl/workspace

As a workaround you can create a .yarnrc file in your root yarn workspace and set the flag to --ignore-workspace-root-check to true

.yarnrc –ignore-workspace-root-check true

@chihab thanks for your contribution! The .yarnrc looks like the best bet for managing this issue. I’ll close this bug, anyone with a similar issue should use the .yarnrc solution above.
