Para usar `EmailStr`, primero instala <a href="https://github.com/JoshData/python-email-validator" class="external-link" target="_blank">`email-validator`</a>.

Asegúrate de crear un [entorno virtual](../virtual-environments.md){.internal-link target=_blank}, activarlo, y luego instalarlo, por ejemplo:

```console
$ pip install email-validator
```

o con:

```console

  }

  private abstract static class AtomicHelper {
    /** Performs an atomic compare-and-set of {@link AggregateFutureState#seenExceptionsField}. */
    abstract void compareAndSetSeenExceptions(
        AggregateFutureState<?> state, @Nullable Set<Throwable> expect, Set<Throwable> update);

    /** Performs an atomic decrement-and-get of {@link AggregateFutureState#remainingField}. */

If you have an older version, you would get errors when trying to use `Annotated`.

Make sure you [Upgrade the FastAPI version](../deployment/versions.md#upgrading-the-fastapi-versions){.internal-link target=_blank} to at least 0.95.1 before using `Annotated`.

For production you would use `fastapi run` instead. 🚀

Internally, **FastAPI CLI** uses <a href="https://www.uvicorn.org" class="external-link" target="_blank">Uvicorn</a>, a high-performance, production-ready, ASGI server. 😎

## `fastapi dev` { #fastapi-dev }

Running `fastapi dev` initiates development mode.
