Damit das funktioniert, müssen Sie `pip install python-dotenv` ausführen.

///

### Die `.env`-Datei

Sie könnten eine `.env`-Datei haben, mit:

```bash

/// tip

For this to work, you need to `pip install python-dotenv`.

///

### The `.env` file

You could have a `.env` file with:

```bash
ADMIN_EMAIL="******@****.***"
APP_NAME="ChimichangApp"
```

这种做法相当常见，有一个名称，这些环境变量通常放在一个名为 `.env` 的文件中，该文件被称为“dotenv”。

/// tip

以点 (`.`) 开头的文件是 Unix-like 系统（如 Linux 和 macOS）中的隐藏文件。

但是，dotenv 文件实际上不一定要具有确切的文件名。

///

Pydantic 支持使用外部库从这些类型的文件中读取。您可以在<a href="https://docs.pydantic.dev/latest/concepts/pydantic_settings/#dotenv-env-support" class="external-link" target="_blank">Pydantic 设置: Dotenv (.env) 支持</a>中阅读更多相关信息。

/// dica

Para que isso funcione você precisa executar `pip install python-dotenv`.

### O arquivo `.env`

Você pode definir um arquivo `.env` com o seguinte conteúdo:

```bash
ADMIN_EMAIL="******@****.***"
APP_NAME="ChimichangApp"
