## FastAPI installieren { #install-fastapi }

Der erste Schritt besteht darin, FastAPI zu installieren.

Stellen Sie sicher, dass Sie eine [virtuelle Umgebung](../virtual-environments.md){.internal-link target=_blank} erstellen, sie aktivieren und dann **FastAPI installieren**:

<div class="termy">

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

---> 100%
```

</div>
