Steps to Reproduce:

Example repo: N/A

1. ionic start test-build blank

[ERROR] An error occurred while running yarn dedupe --non-interactive (exit code
        1):

        error The dedupe command isn't necessary. `yarn install` will already
        dedupe.

Oh, that's so friendly of yarn to exit 1 on unnecessary commands. Thanks, I will fix this.
