How does yarn link work?

[derHodrig]

What I expect to work

cd /path/to/my-local-package
yarn link

cd /path/to/my-project
yarn link "my-local-package"

Now "my-local-package" should be a dependency inside "my-project" but instead i got this error "Usage Error: Invalid destination 'my-local-package'; Can't link the project to itself"

Is it because my local package has a scope prefix? yarn link @my-scope/shared-components is not working.

-- I do not work with workspaces --

For example with Bun this works just as expected.

I suggest taking a look at the documentation for the command at https://yarnpkg.com/cli/link or by running

yarn link --help

In your case you would run

yarn link /path/to/my-local-package

from /path/to/my-project.

Okay check.
I was worried i have to realign my codebase to use workspaces.
