Wenn Sie FastAPI installieren (z. B. mit `pip install "fastapi[standard]"`), erhalten Sie ein Kommandozeilenprogramm, das Sie im Terminal ausführen können.

Um Ihre FastAPI-App für die Entwicklung auszuführen, können Sie den Befehl `fastapi dev` verwenden:

<div class="termy">

```console
$ <font color="#4E9A06">fastapi</font> dev

When you install FastAPI (e.g. with `pip install "fastapi[standard]"`), it comes with a command line program you can run in the terminal.

To run your FastAPI app for development, you can use the `fastapi dev` command:

<div class="termy">

```console
$ <font color="#4E9A06">fastapi</font> dev

Quando você instala o FastAPI (por exemplo, com `pip install "fastapi[standard]"`), ele vem com um programa de linha de comando que você pode executar no terminal.

Para executar sua aplicação FastAPI durante o desenvolvimento, você pode usar o comando `fastapi dev`:
