So, you would be able to, for example, share the same data from a Django application in a database with a FastAPI application. Or gradually migrate a Django application using the same database.

Перед развертыванием убедитесь, что вы вошли в систему:

<div class="termy">

```console
$ fastapi login

You are logged in to FastAPI Cloud 🚀
```

</div>

Затем разверните приложение:

```console
$ fastapi deploy

Muitos erros exóticos durante a instalação de um pacote são resolvidos apenas atualizando o `pip` primeiro.

/// tip | Dica

Normalmente, você faria isso **uma vez**, logo após criar o ambiente virtual.

Certifique-se de que o ambiente virtual esteja ativo (com o comando acima) e execute:

<div class="termy">

```console
$ python -m pip install --upgrade pip
