А именно: `pip install python-multipart`.

Это связано с тем, что **OAuth2** использует "данные формы" для передачи `имени пользователя` и `пароля`.

## Installatie

<div class="termy">

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

---> 100%
```

</div>

**Opmerking**: Zet `"fastapi[standard]"` tussen aanhalingstekens om ervoor te zorgen dat het werkt in alle terminals.

## Voorbeeld

            String passwd = cliRequest.commandLine.getOptionValue(CLIManager.ENCRYPT_PASSWORD);

            if (passwd == null) {
                Console cons = System.console();
                char[] password = (cons == null) ? null : cons.readPassword("Password: ");
                if (password != null) {
                    // Cipher uses Strings

	Ex: `pip install python-multipart`.

	Isso ocorre porque o **OAuth2** usa "dados de um formulário" para mandar o **username** e **senha**.

Execute esse exemplo com:

<div class="termy">

```console
$ uvicorn main:app --reload

<span style="color: green;">INFO</span>:     Uvicorn running on http://127.0.0.1:8000 (Press CTRL+C to quit)
```

</div>

## Verifique-o

```
fastapi>=0.68.0,<0.69.0
pydantic>=1.8.0,<2.0.0
uvicorn>=0.15.0,<0.16.0
```

Устанавливать зависимости проще всего с помощью `pip`:

<div class="termy">

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

</div>

/// info | "Информация"

Существуют и другие инструменты управления зависимостями.

Z. B. `pip install python-multipart`.

Das, weil **OAuth2** „Formulardaten“ zum Senden von `username` und `password` verwendet.

///

Führen Sie das Beispiel aus mit:

<div class="termy">

```console
$ uvicorn main:app --reload

<span style="color: green;">INFO</span>:     Uvicorn running on http://127.0.0.1:8000 (Press CTRL+C to quit)
```

</div>

## Überprüfen

安装命令： `pip install python-multipart`。

这是因为 **OAuth2** 使用**表单数据**发送 `username` 与 `password`。

///

用下面的命令运行该示例：

<div class="termy">

```console
$ uvicorn main:app --reload

<span style="color: green;">INFO</span>:     Uvicorn running on http://127.0.0.1:8000 (Press CTRL+C to quit)
```

</div>

## 查看文档

```
fastapi>=0.68.0,<0.69.0
pydantic>=1.8.0,<2.0.0
uvicorn>=0.15.0,<0.16.0
```

E você normalmente instalaria essas dependências de pacote com `pip`, por exemplo:

<div class="termy">

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

</div>

/// info

Há outros formatos e ferramentas para definir e instalar dependências de pacote.
