  I installed @aryairani/test-almost-empty/main as
  aryairani_test_almost_empty_main.

test/main> pull @aryairani/test-almost-empty/main a.b

⚠️

Sorry, I wasn’t sure how to process your request:

  I think you want to merge @aryairani/test-almost-empty/main
  into the a.b namespace, but the `pull` command only supports
  merging into the top level of a local project branch.

You can run `help pull` for more information on using `pull`.

test/main> pull @aryairani/test-almost-empty/main a

  I think you want to merge @aryairani/test-almost-empty/main
  into the a branch, but it doesn't exist. If you want, you can
  create it with `branch.empty a`, and then `pull` again.

test/main> pull @aryairani/test-almost-empty/main .a
