您可以使用以下命令安装 ASGI 兼容服务器：

//// tab | Uvicorn

* <a href="https://www.uvicorn.org/" class="external-link" target="_blank">Uvicorn</a>，一个快如闪电 ASGI 服务器，基于 uvloop 和 httptools 构建。

<div class="termy">

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

---> 100%
```

</div>

/// tip

通过添加`standard`，Uvicorn 将安装并使用一些推荐的额外依赖项。

其中包括`uvloop`，它是`asyncio`的高性能替代品，它提供了巨大的并发性能提升。

///

////

     由于此文件**不经常更改**，Docker 将检测到它并在这一步中使用**缓存**，从而为下一步启用缓存。

4. 安装需求文件中的包依赖项。

     `--no-cache-dir` 选项告诉 `pip` 不要在本地保存下载的包，因为只有当 `pip` 再次运行以安装相同的包时才会这样，但在与容器一起工作时情况并非如此。

     /// note | 笔记

     `--no-cache-dir` 仅与 `pip` 相关，与 Docker 或容器无关。

     ///

     `--upgrade` 选项告诉 `pip` 升级软件包（如果已经安装）。

     因为上一步复制文件可以被 **Docker 缓存** 检测到，所以此步骤也将 **使用 Docker 缓存**（如果可用）。

<div class="termy">

```console
$ which pip

some/directory/fastapi/env/bin/pip
```

</div>

////

//// tab | Windows PowerShell

<div class="termy">

```console
$ Get-Command pip

some/directory/fastapi/env/bin/pip
```

</div>

////

`env/bin/pip`に`pip`バイナリが表示される場合は、正常に機能しています。🎉


/// tip | "豆知識"

この環境で`pip`を使って新しいパッケージをインストールするたびに、仮想環境を再度有効化します。
