Par exemple, pour installer Uvicorn :

<div class="termy">

```console
$ pip install "uvicorn[standard]"

---> 100%
```

</div>

Un processus similaire s'appliquerait à tout autre programme de serveur ASGI.

/// tip | Astuce

En ajoutant `standard`, Uvicorn va installer et utiliser quelques dépendances supplémentaires recommandées.

Zum Beispiel, um Uvicorn zu installieren:

<div class="termy">

```console
$ pip install "uvicorn[standard]"

</div>

Ein ähnlicher Prozess würde für jedes andere ASGI-Serverprogramm gelten.

Durch das Hinzufügen von `standard` installiert und verwendet Uvicorn einige empfohlene zusätzliche Abhängigkeiten.

/// note | Technische Details

ASGI ist ein neuer „Standard“, welcher von Mitgliedern des Django-Kernteams entwickelt wird. Es handelt sich immer noch nicht um einen „Python-Standard“ (ein PEP), obwohl sie gerade dabei sind, das zu tun.

```console
$ pip install "fastapi[standard]"

                })
            .named(
                "ForwardingSortedMap[SafeTreeMap] with no comparator and standard "
                    + "implementations")

copies of a package at different versions if the package is
imported normally and vendored by the standard library.

Vendored packages are internally renamed with a "vendor/" prefix
to preserve the invariant that all packages have distinct paths.
This is necessary to avoid compiler and linker conflicts. Adding
a "vendor/" prefix also maintains the invariant that standard
library packages begin with a dotless path element.

例如，安裝 Uvicorn：

<div class="termy">

```console
$ pip install "uvicorn[standard]"

---> 100%
```

</div>

其他 ASGI 伺服器的安裝流程也大致相同。

/// tip

加入 `standard` 會讓 Uvicorn 安裝並使用一些建議的額外相依套件。

其中包含 `uvloop`，它是 `asyncio` 的高效能替代實作，可大幅提升並行效能。

當你用 `pip install "fastapi[standard]"` 安裝 FastAPI 時，也會一併取得 `uvicorn[standard]`。
