FastAPI 是站在以下巨人的肩膀上：

* [Starlette](https://www.starlette.dev/) 負責 Web 部分。
* [Pydantic](https://docs.pydantic.dev/) 負責資料部分。

## 安裝 { #installation }

建立並啟用一個[虛擬環境](https://fastapi.tiangolo.com/zh-hant/virtual-environments/)，然後安裝 FastAPI：

<div class="termy">

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

---> 100%
```

</div>

**注意**：請務必將 `"fastapi[standard]"` 用引號包起來，以確保在所有終端機中都能正常運作。

要使用 `EmailStr`，請先安裝 [`email-validator`](https://github.com/JoshData/python-email-validator)。

請先建立一個[虛擬環境](../virtual-environments.md)、啟用它，然後安裝，例如：

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

或：

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

这是一个非常简单和简短的教程。如果你想了解一般的数据库、SQL 或更高级的功能，请查看 [SQLModel 文档](https://sqlmodel.tiangolo.com/)。

## 安装 `SQLModel` { #install-sqlmodel }

首先，确保你创建并激活了[虚拟环境](../virtual-environments.md)，然后安装 `sqlmodel`：

<div class="termy">

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

</div>

## インストール { #installation }

[仮想環境](https://fastapi.tiangolo.com/ja/virtual-environments/) を作成して有効化し、それから FastAPI をインストールします。

<div class="termy">

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

---> 100%
```

</div>

## 설치 { #installation }

[가상 환경](https://fastapi.tiangolo.com/ko/virtual-environments/)을 생성하고 활성화한 다음 FastAPI를 설치하세요:

<div class="termy">

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

---> 100%
```

</div>

이 튜토리얼은 매우 간단하고 짧습니다. 데이터베이스 기본 개념, SQL, 또는 더 고급 기능에 대해 배우고 싶다면, [SQLModel 문서](https://sqlmodel.tiangolo.com/)를 참고하세요.

## `SQLModel` 설치하기 { #install-sqlmodel }

먼저, [가상 환경](../virtual-environments.md)을 생성하고 활성화한 다음, `sqlmodel`을 설치하세요:

<div class="termy">

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

</div>
