If you want to install the standard dependencies but without the `fastapi-cloud-cli`, you can install with `pip install "fastapi[standard-no-fastapi-cloud-cli]"`.

///

/// tip

```console
$ fastapi dev main.py
```

Ancak `fastapi` komutunu her çağırdığınızda doğru path'i geçmeyi hatırlamanız gerekir.

Ayrıca, [VS Code Extension](editor-support.md) veya [FastAPI Cloud](https://fastapicloud.com) gibi diğer araçlar da bunu bulamayabilir; bu yüzden `pyproject.toml` içindeki `entrypoint`'i kullanmanız önerilir.

## `fastapi dev` { #fastapi-dev }

Let's start with an example and then see it in detail.

We create an async function `lifespan()` with `yield` like this:
