FastAPI hat Unterstützung für `Annotated` hinzugefügt (und begonnen, es zu empfehlen) in der Version 0.95.0.

Wenn Sie eine ältere Version haben, würden Sie Fehler erhalten, beim Versuch, `Annotated` zu verwenden.

Stellen Sie sicher, dass Sie [die FastAPI-Version aktualisieren](../deployment/versions.md#upgrading-the-fastapi-versions){.internal-link target=_blank}, auf mindestens Version 0.95.1, bevor Sie `Annotated` verwenden.

<div class="termy">

```console
$ pip install sqlmodel
---> 100%
