/// tip | Dica

Toda vez que você instalar um **novo pacote** naquele ambiente, **ative** o ambiente novamente.

Isso garante que, se você usar um **programa de terminal (<abbr title="Command Line Interface – Interface de Linha de Comando">CLI</abbr>)** instalado por esse pacote, você usará aquele do seu ambiente virtual e não qualquer outro que possa ser instalado globalmente, provavelmente com uma versão diferente do que você precisa.

/// tip | Consejo

Cada vez que instales un **nuevo paquete** en ese entorno, **activa** el entorno de nuevo.

Esto asegura que si usas un programa de **terminal (<abbr title="command line interface – interfaz de línea de comandos">CLI</abbr>)** instalado por ese paquete, uses el de tu entorno virtual y no cualquier otro que podría estar instalado globalmente, probablemente con una versión diferente a la que necesitas.

最簡單的 FastAPI 檔案可能看起來像這樣：

{* ../../docs_src/first_steps/tutorial001.py *}

將其複製到一個名為 `main.py` 的文件中。

執行即時重新載入伺服器（live server）：
