yarn unlink
Unlink the current project from a previously linked one
yarn unlink <TARGETS…>
This command will remove any resolutions in the project-level manifest that would have been added via a yarn link with similar arguments.
If the --all flag is used without any arguments, Yarn will remove all resolutions that use the portal: protocol.
If the --all flag is used with a path argument, Yarn will unlink all workspaces from the specified project.
Otherwise, you can specify package names (with glob support) or paths to individual packages to unlink specific resolutions.
Unlink all portal resolutions, or all workspaces from the target project
