<div class="termy">

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

---> 100%
```

</div>

...이는 코드를 실행하는 서버로 사용할 수 있는 `uvicorn` 또한 포함하고 있습니다.

/// note | 참고

부분적으로 설치할 수도 있습니다.

애플리케이션을 운영 환경에 배포하려는 경우 다음과 같이 합니다:

```
pip install fastapi
```

추가로 서버 역할을 하는 `uvicorn`을 설치합니다:

```
pip install uvicorn
```

사용하려는 각 선택적인 의존성에 대해서도 동일합니다.

///

## Install `websockets` { #install-websockets }

Make sure you create a [virtual environment](../virtual-environments.md){.internal-link target=_blank}, activate it, and install `websockets` (a Python library that makes it easy to use the "WebSocket" protocol):

<div class="termy">

```console
$ pip install websockets

---> 100%
```

</div>

If you don't want to include the `standard` optional dependencies, you can install with `pip install fastapi` instead of `pip install "fastapi[standard]"`.

### Without `fastapi-cloud-cli` { #without-fastapi-cloud-cli }

If you want to install FastAPI with the standard dependencies but without the `fastapi-cloud-cli`, you can install with `pip install "fastapi[standard-no-fastapi-cloud-cli]"`.

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

그리고 일반적으로 패키지 종속성은 `pip`로 설치합니다. 예를 들어:

<div class="termy">

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

</div>

/// info | 정보

패키지 종속성을 정의하고 설치하기 위한 방법과 도구는 다양합니다.

나중에 아래 세션에서 Poetry를 사용한 예시를 보이겠습니다. 👇
