## Install `WebSockets`

Make sure you create a [virtual environment](../virtual-environments.md){.internal-link target=_blank}, activate it, and install `websockets`:

<div class="termy">

```console
$ pip install websockets

---> 100%
```

</div>

## WebSockets client

### In production

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.

For example, to install Uvicorn:

<div class="termy">

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

---> 100%
```

</div>

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
$ pip install python-multipart
```

This is because **OAuth2** uses "form data" for sending the `username` and `password`.

Run the example with:

### 仮想環境の有効化

新しい環境を有効化するには:

//// tab | Linux, macOS

<div class="termy">

```console
$ source ./env/bin/activate
```

</div>

////

//// tab | Windows PowerShell

<div class="termy">

```console
$ .\env\Scripts\Activate.ps1
```

</div>

////

//// tab | Windows Bash

* `/items/private/`
* `/users/{user_id}/activate`
* `/items/pro/`

그 다음 각각에 대해 그저 의존성과 하위 의존성을 사용하여 다른 권한 요구 사항을 추가할 수 있을 겁니다:

```mermaid

current_user(["current_user"])
active_user(["active_user"])
admin_user(["admin_user"])
paying_user(["paying_user"])

public["/items/public/"]
private["/items/private/"]
activate_user["/users/{user_id}/activate"]
pro_items["/items/pro/"]

## 3. Activate ILM versioning features

This will only work with a versioned bucket, take a look at [Bucket Versioning Guide](https://min.io/docs/minio/linux/administration/object-management/object-versioning.html) for more understanding.

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

```console
$ pip install email-validator
```

or with:

```console
$ pip install "pydantic[email]"
```

### Install `pydantic-settings`

First, make sure you create your [virtual environment](../virtual-environments.md){.internal-link target=_blank}, activate it, and then install the `pydantic-settings` package:

<div class="termy">

```console
$ pip install pydantic-settings
---> 100%
```

</div>
