## Abhängigkeiten installieren { #install-dependencies }

Stellen Sie sicher, dass Sie eine [virtuelle Umgebung](../virtual-environments.md){.internal-link target=_blank} erstellen, sie aktivieren und `jinja2` installieren:

<div class="termy">

```console
$ pip install jinja2

---> 100%
```

</div>

Aus diesem Grund sind die aktuellen Versionen immer noch `0.x.x`, was darauf hindeutet, dass jede Version möglicherweise nicht abwärtskompatible Änderungen haben könnte. Dies folgt den Konventionen der <a href="https://semver.org/" class="external-link" target="_blank">semantischen Versionierung</a>.

É por isso que as versões atuais ainda são `0.x.x`, isso reflete que cada versão pode potencialmente ter mudanças significativas. Isso segue as convenções de <a href="https://semver.org/" class="external-link" target="_blank">Versionamento Semântico</a>.
