Para instalarlo manualmente, asegúrate de crear un [entorno virtual](../../virtual-environments.md){.internal-link target=_blank}, activarlo, y luego instalarlo con:

```console
$ pip install python-multipart
```

Esto se debe a que **OAuth2** utiliza "form data" para enviar el `username` y `password`.

///

Ejecuta el ejemplo con:

<div class="termy">

```console
$ fastapi dev main.py

Pero puedes devolver un `JSONResponse` directamente desde tus *path operations*.

Esto podría ser útil, por ejemplo, para devolver headers o cookies personalizados.

## Devolver una `Response`

De hecho, puedes devolver cualquier `Response` o cualquier subclase de ella.
