First, install the `pydantic-settings` package:

<div class="termy">

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

</div>

It also comes included when you install the `all` extras with:

<div class="termy">

```console
$ pip install "fastapi[all]"
---> 100%
```

</div>

!!! info

你可以使用 Python 的 `venv` 模块在一个目录中创建虚拟环境：

<div class="termy">

```console
$ python -m venv env
```

</div>

这将使用 Python 程序创建一个 `./env/` 目录，然后你将能够为这个隔离的环境安装软件包。

### 激活虚拟环境

使用以下方法激活新环境：

=== "Linux, macOS"

    <div class="termy">

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

    </div>

=== "Windows PowerShell"

    <div class="termy">

    ```console

您可以在 shell 中创建和使用环境变量，而无需使用 Python：

=== "Linux、macOS、Windows Bash"

    <div class="termy">

    ```console
    // 您可以创建一个名为 MY_NAME 的环境变量
    $ export MY_NAME="Wade Wilson"

    // 然后您可以与其他程序一起使用它，例如
    $ echo "Hello $MY_NAME"

    Hello Wade Wilson
    ```

    </div>

=== "Windows PowerShell"

    <div class="termy">

    ```console
    // 创建一个名为 MY_NAME 的环境变量

Ta zmienna `app` jest tą samą zmienną, do której odnosi się `uvicorn` w poleceniu:

<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>

Jeśli stworzysz swoją aplikację, np.:

```Python hl_lines="3"
{!../../../docs_src/first_steps/tutorial002.py!}

& ⤴️ ⚫️ 🔜 ❎ 🚮 📨 👆 Uvicorn 🏃‍♂ 🔛 `http://127.0.0.1:8000`.

🔜 ▶️ Traefik:

<div class="termy">

```console
$ ./traefik --configFile=traefik.toml

INFO[0000] Configuration loaded from file: /home/user/awesomeapi/traefik.toml
```

</div>

&amp; 🔜 ▶️ 👆 📱 ⏮️ Uvicorn, ⚙️ `--root-path` 🎛:

<div class="termy">

```console
$ uvicorn main:app --root-path /api/v1
