🐞 V7: `api` has original `Setup()`
🐞 V7: `api` has original `Setup()`

`api` now has its original, custom `Setup()` function. Previously it had
been refactored to use the `BaseCommand`'s `Setup()` function, but that
would attempt to target CF while creating a new client. The `api`
command does not assume that there is a targeted CF, so this would
cause errors.

No API endpoint set. Use 'cf login' or 'cf api' to target an endpoint.
