そして通常、例えば `pip` を使ってこれらのパッケージの依存関係をインストールします：

<div class="termy">

```console
$ pip install -r requirements.txt
---> 100%
Successfully installed fastapi pydantic uvicorn
```

</div>

/// info

パッケージの依存関係を定義しインストールするためのフォーマットやツールは他にもあります。

Poetryを使った例は、後述するセクションでご紹介します。👇

### **FastAPI**コードを作成する

* `app` ディレクトリを作成し、その中に入ります
* 空のファイル `__init__.py` を作成します
