```

And you would normally install those package dependencies with `pip`, for example:

<div class="termy">

```console
$ pip install -r requirements.txt
---> 100%
Successfully installed fastapi pydantic
```

</div>

### Major Features and Improvements

### Sin Dependencias `standard`

Existen algunas dependencias adicionales que podrías querer instalar.

Dependencias opcionales adicionales de Pydantic:

## Where are Packages Installed { #where-are-packages-installed }

## Instalar `PyJWT`

Necesitamos instalar `PyJWT` para generar y verificar los tokens JWT en Python.

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

<div class="termy">

```console
$ pip install pyjwt

---> 100%
```

</div>

/// info | Información

When you install Python, you might be asked if you want to update the `PATH` environment variable.

//// 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.

Now `fastapi` doesn't include those standard dependencies unless you install with `pip install "fastapi[standard]"`.

Before, you would install `pip install fastapi`, now you should include the `standard` optional dependencies (unless you want to exclude one of those): `pip install "fastapi[standard]"`.

However, if you use the `pip install fastapi` command, the `python-multipart` package is not included by default.

To install it manually, make sure you create a [virtual environment](../../virtual-environments.md){.internal-link target=_blank}, activate it, and then install it with:

```console

### Sem as dependências `standard`

Se você não deseja incluir as dependências opcionais `standard`, você pode instalar utilizando `pip install fastapi` ao invés de `pip install "fastapi[standard]"`.

### Dpendências opcionais adicionais

Existem algumas dependências adicionais que você pode querer instalar.

Dependências opcionais adicionais do Pydantic:

## Install the Server Program { #install-the-server-program }

When you install FastAPI, it comes with a production server, Uvicorn, and you can start it with the `fastapi run` command.

But you can also install an ASGI server manually.

Make sure you create a [virtual environment](../virtual-environments.md){.internal-link target=_blank}, activate it, and then you can install the server application.
