## Upgrade `pip` { #upgrade-pip }

/// tip

If you use [`uv`](https://github.com/astral-sh/uv) you would use it to install things instead of `pip`, so you don't need to upgrade `pip`. 😎

///

If you are using `pip` to install packages (it comes by default with Python), you should **upgrade** it to the latest version.

<div class="termy">

```console
$ python -m pip install --upgrade pip

---> 100%
```

</div>

/// tip | 提示

有时在尝试升级 pip 时，你可能会遇到 **`No module named pip`** 错误。

如果发生这种情况，使用下面的命令来安装并升级 pip：

<div class="termy">

```console
$ python -m ensurepip --upgrade

---> 100%
```

</div>

该命令会在尚未安装 pip 时进行安装，并确保安装的 pip 版本不早于 `ensurepip` 提供的版本。

Make sure you create a [virtual environment](../virtual-environments.md), activate it, and then **install FastAPI**:

<div class="termy">

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

---> 100%
```

</div>

/// note

<div class="termy">

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

---> 100%
```

</div>

/// note | 注意

当您使用 `pip install "fastapi[standard]"` 安装时，它会附带一些默认的可选标准依赖项，其中包括 `fastapi-cloud-cli`，它可以让您部署到 [FastAPI Cloud](https://fastapicloud.com)。

如果您不想安装这些可选依赖，可以选择安装 `pip install fastapi`。

如果您想安装标准依赖但不包含 `fastapi-cloud-cli`，可以使用 `pip install "fastapi[standard-no-fastapi-cloud-cli]"` 安装。

## Install

See the [TensorFlow install guide](https://www.tensorflow.org/install) for the
[pip package](https://www.tensorflow.org/install/pip), to
[enable GPU support](https://www.tensorflow.org/install/gpu), use a
[Docker container](https://www.tensorflow.org/install/docker), and
[build from source](https://www.tensorflow.org/install/source).

    and the
    [FastAPI docs for Response Model](https://fastapi.tiangolo.com/tutorial/response-model/).

    **Note**: `ujson` is not included with FastAPI and must be installed
    separately, e.g. `pip install ujson`.
    """

    def render(self, content: Any) -> bytes:
        assert ujson is not None, "ujson must be installed to use UJSONResponse"
        return ujson.dumps(content, ensure_ascii=False).encode("utf-8")

<div class="termy">

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

---> 100%
```

</div>

/// note | 備考

`pip install "fastapi[standard]"` でインストールすると、`fastapi-cloud-cli` を含むいくつかのデフォルトのオプション標準依存関係が付属します。これにより、[FastAPI Cloud](https://fastapicloud.com) にデプロイできます。

これらのオプション依存関係が不要な場合は、代わりに `pip install fastapi` をインストールできます。

4. 요구사항 파일에 있는 패키지 의존성을 설치합니다.

    `--no-cache-dir` 옵션은 `pip`가 다운로드한 패키지를 로컬에 저장하지 않도록 합니다. 이는 `pip`가 같은 패키지를 설치하기 위해 다시 실행될 때만 의미가 있지만, 컨테이너 작업에서는 그렇지 않기 때문입니다.

    /// note | 참고

    `--no-cache-dir`는 `pip`에만 관련되어 있으며 Docker나 컨테이너와는 관련이 없습니다.

    ///

    `--upgrade` 옵션은 이미 설치된 패키지가 있다면 `pip`가 이를 업그레이드하도록 합니다.

    The `--no-cache-dir` option tells `pip` to not save the downloaded packages locally, as that is only if `pip` was going to be run again to install the same packages, but that's not the case when working with containers.

    /// note

    The `--no-cache-dir` is only related to `pip`, it has nothing to do with Docker or containers.

    ///

    The `--upgrade` option tells `pip` to upgrade the packages if they are already installed.
