Переконайтесь, що Ви створили [віртуальне середовище](../virtual-environments.md){.internal-link target=_blank}, активували його, а потім встановили пакет, наприклад:

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

or with:

```console
$ pip install "pydantic[email]"
```

            method.setAccessible(true);
          } catch (AccessControlException e) {
            // OK: the method is accessible to us anyway. The setAccessible call is only for
            // unusual execution environments where that might not be true.
          }
          builder.put(method.getName(), method);
        }
      }
      typeVariableMethods = builder.buildKeepingLast();
    }

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
$ pip install "pydantic[email]"
```

## Instalar `SQLModel`

Primero, asegúrate de crear tu [entorno virtual](../virtual-environments.md){.internal-link target=_blank}, actívalo, y luego instala `sqlmodel`:

<div class="termy">

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

</div>

## Crear la App con un Solo Modelo

I'll tell you a bit more about these **concepts** here, and that would hopefully give you the **intuition** you would need to decide how to deploy your API in very different environments, possibly even in **future** ones that don't exist yet.

By considering these concepts, you will be able to **evaluate and design** the best way to deploy **your own APIs**.

## Instalación

Crea y activa un <a href="https://fastapi.tiangolo.com/virtual-environments/" class="external-link" target="_blank">entorno virtual</a> y luego instala FastAPI:

<div class="termy">

```console
$ pip install "fastapi[standard]"

---> 100%
```

</div>

* <a href="https://docs.pydantic.dev/" class="external-link" target="_blank">Pydantic</a> para a parte de dados.

## Instalação

Crie e ative um <a href="https://fastapi.tiangolo.com/pt/virtual-environments/" class="external-link" target="_blank">ambiente virtual</a>, e então instale o FastAPI:

<div class="termy">

```console
$ pip install "fastapi[standard]"

---> 100%
```

</div>

## Version 4.7.0

_2020-05-17_

 *  New: `HandshakeCertificates.Builder.addInsecureHost()` makes it easy to turn off security in
    private development environments that only carry test data. Prefer this over creating an
    all-trusting `TrustManager` because only hosts on the allowlist are insecure. From
    [our DevServer sample][dev_server]:

    ```kotlin

    `Protocol.H2_PRIOR_KNOWLEDGE` as the lone protocol on an `OkHttpClient.Builder`. This mode
    only supports `http:` URLs and is best suited in closed environments where HTTPS is
    inappropriate.

 *  New: `HttpUrl.get(String)` is an alternative to `HttpUrl.parse(String)` that throws an exception

이 튜토리얼은 매우 간단하고 짧습니다. 데이터베이스 기본 개념, SQL, 또는 더 복잡한 기능에 대해 배우고 싶다면, <a href="https://sqlmodel.tiangolo.com/" class="external-link" target="_blank">SQLModel 문서</a>를 참고하세요.

## `SQLModel` 설치하기

먼저, [가상 환경](../virtual-environments.md){.internal-link target=_blank}을 생성하고 활성화한 다음, `sqlmodel`을 설치하세요:

<div class="termy">

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

</div>
