For example, to install Uvicorn:

<div class="termy">

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

---> 100%
```

</div>

A similar process would apply to any other ASGI server program.

/// tip

By adding the `standard`, Uvicorn will install and use some recommended extra dependencies.

## Dependências { #dependencies }

O FastAPI depende do Pydantic e do Starlette.

### Dependências `standard` { #standard-dependencies }

Quando você instala o FastAPI com `pip install "fastapi[standard]"`, ele vem com o grupo `standard` de dependências opcionais:

Utilizado pelo Pydantic:

* [`email-validator`](https://github.com/JoshData/python-email-validator) - para validação de email.

## Зависимости { #dependencies }

FastAPI зависит от Pydantic и Starlette.

### Зависимости `standard` { #standard-dependencies }

Когда вы устанавливаете FastAPI с помощью `pip install "fastapi[standard]"`, он идёт с группой опциональных зависимостей `standard`:

Используется Pydantic:

Например, чтобы установить Uvicorn:

<div class="termy">

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

---> 100%
```

</div>

Аналогично устанавливаются и другие ASGI‑серверы.

/// tip | Совет

С добавлением `standard` Uvicorn установит и будет использовать ряд рекомендованных дополнительных зависимостей.

    @Test
    public void testDecodePartialData() {
        // Create a buffer with only standard lease data (no directory-specific data)
        byte[] buffer = new byte[56]; // Header + name + padding + standard lease data only

        // Write minimal header
        SMBUtil.writeInt4(0, buffer, 0); // Next
        SMBUtil.writeInt2(16, buffer, 4); // NameOffset

* [`uvicorn`](https://www.uvicorn.dev) - 用於載入並服務你的應用的伺服器。這包含 `uvicorn[standard]`，其中含有一些高效能服務所需的依賴（例如 `uvloop`）。
* `fastapi-cli[standard]` - 提供 `fastapi` 指令。
    * 其中包含 `fastapi-cloud-cli`，可讓你將 FastAPI 應用部署到 [FastAPI Cloud](https://fastapicloud.com)。

### 不含 `standard` 依賴套件 { #without-standard-dependencies }

如果你不想包含 `standard` 可選依賴，可以改用 `pip install fastapi`（而不是 `pip install "fastapi[standard]"`）。

/// note | 참고

`pip install "fastapi[standard]"`로 설치하면 `fastapi-cloud-cli`를 포함한 몇 가지 기본 선택적 standard 의존성이 함께 설치되며, 이를 사용해 [FastAPI Cloud](https://fastapicloud.com)에 배포할 수 있습니다.

이러한 선택적 의존성이 필요 없다면 `pip install fastapi`로 대신 설치할 수 있습니다.
