Asegúrate de crear un [entorno virtual](../virtual-environments.md){.internal-link target=_blank}, activarlo e instalar `jinja2`:

<div class="termy">

```console
$ pip install jinja2

---> 100%

만약 무거운 백그라운드 작업을 수행해야하고 동일한 프로세스에서 실행할 필요가 없는 경우 (예: 메모리, 변수 등을 공유할 필요가 없음) <a href="https://docs.celeryq.dev" class="external-link" target="_blank">`Celery`</a>와 같은 큰 도구를 사용하면 도움이 될 수 있습니다.
