## 其他返回类型注解 { #other-return-type-annotations }

有些情况下你会返回一些不是有效 Pydantic 字段的内容，并在函数上做了相应注解，只是为了获得工具链（编辑器、mypy 等）的支持。

### 直接返回 Response { #return-a-response-directly }

最常见的情况是[直接返回 Response，详见进阶文档](../advanced/response-directly.md)。

{* ../../docs_src/response_model/tutorial003_02_py310.py hl[8,10:11] *}

这个简单场景 FastAPI 会自动处理，因为返回类型注解是 `Response`（或其子类）。

### パッケージを直接インストールする { #install-packages-directly }

急いでいて、プロジェクトのパッケージ要件を宣言するファイルを使いたくない場合、パッケージを直接インストールできます。

/// tip | 豆知識

プログラムが必要とするパッケージとバージョンをファイル（例えば `requirements.txt` や `pyproject.toml` ）に記載しておくのは、（とても）良い考えです。
