アプリケーションの**パッケージ要件**は通常、何らかのファイルに記述されているはずです。

パッケージ要件は主に**インストール**するために使用するツールに依存するでしょう。

最も一般的な方法は、`requirements.txt` ファイルにパッケージ名とそのバージョンを 1 行ずつ書くことです。

もちろん、[FastAPI バージョンについて](versions.md){.internal-link target=_blank}で読んだのと同じアイデアを使用して、バージョンの範囲を設定します。

例えば、`requirements.txt` は次のようになります：

```
fastapi>=0.68.0,<0.69.0
pydantic>=1.8.0,<2.0.0
uvicorn>=0.15.0,<0.16.0
```
