## Installer le programme serveur

Vous pouvez installer un serveur compatible ASGI avec :

//// tab | Uvicorn

    cat "$FROM_ENV"
    source "$FROM_ENV"
    rm "$FROM_ENV"
  fi
fi

# If building installer wheels, set the required environment variables that are
# read by setup.py.
if [[ "$TFCI_INSTALLER_WHL_ENABLE" == 1 ]]; then
  export collaborator_build=True
  # If building nightly installer wheels, set the project name to
  # nightly equivalent.
  if [[ "$TFCI_NIGHTLY_UPDATE_VERSION_ENABLE" == 1 ]]; then

L'utiliser dans votre éditeur est ce qui vous montre vraiment les avantages de FastAPI, en voyant le peu de code que vous avez à écrire, toutes les vérifications de type, l'autocomplétion, etc.

## Installer FastAPI

La première étape consiste à installer FastAPI.

Pour le tutoriel, vous voudrez peut-être l'installer avec toutes les dépendances et fonctionnalités optionnelles :

<div class="termy">

```console
$ pip install fastapi[all]

//// tab | Linux, macOS

Let's say you install Python and it ends up in a directory `/opt/custompython/bin`.

If you say yes to update the `PATH` environment variable, then the installer will add `/opt/custompython/bin` to the `PATH` environment variable.

It could look like this:

```plaintext
/usr/local/bin:/usr/bin:/bin:/usr/sbin:/sbin:/opt/custompython/bin
```
