## `fastapi`-Version pinnen

Als Erstes sollten Sie die Version von **FastAPI**, die Sie verwenden, an die höchste Version „pinnen“, von der Sie wissen, dass sie für Ihre Anwendung korrekt funktioniert.

Angenommen, Sie verwenden in Ihrer Anwendung die Version `0.45.0`.

## Beispiel

Betrachten wir als einfaches Beispiel eine Dateistruktur ähnlich der in [Größere Anwendungen](../tutorial/bigger-applications.md){.internal-link target=_blank} und [Testen](../tutorial/testing.md){.internal-link target=_blank}:

```
.
├── app
│   ├── __init__.py
│   ├── main.py
│   └── test_main.py
```

Die Datei `main.py` hätte als Inhalt:

{* ../../docs_src/async_tests/main.py *}
