# FastAPI CLI

**FastAPI CLI** 是一個命令列程式，能用來運行你的 FastAPI 應用程式、管理你的 FastAPI 專案等。

當你安裝 FastAPI（例如使用 `pip install "fastapi[standard]"`），它會包含一個叫做 `fastapi-cli` 的套件，這個套件提供了 `fastapi` 命令。

要運行你的 FastAPI 應用程式來進行開發，你可以使用 `fastapi dev` 命令：

<div class="termy">

```console
$ <font color="#4E9A06">fastapi</font> dev <u style="text-decoration-style:single">main.py</u>
<font color="#3465A4">INFO    </font> Using path <font color="#3465A4">main.py</font>
