请确保您创建并激活一个[虚拟环境](../virtual-environments.md){.internal-link target=_blank}，然后**安装 FastAPI**：

<div class="termy">

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

---> 100%
```

</div>

/// note

当您使用 `pip install "fastapi[standard]"` 进行安装时，它会附带一些默认的可选标准依赖项。

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