Bu environment'e **yeni bir package** kurduğunuz her seferinde environment'i yeniden **aktif edin**.

Böylece, o package'in kurduğu bir **terminal (<abbr title="command line interface - Komut Satırı Arayüzü">CLI</abbr>) programı** kullanıyorsanız, global olarak kurulu (ve muhtemelen ihtiyacınız olandan farklı bir versiyona sahip) başka bir program yerine, virtual environment'inizdeki programı kullanmış olursunuz.

Bunu yapmak için, program komutunun hemen öncesinde ve aynı satırda tanımlayın:

<div class="termy">

```console
// Create an env var MY_NAME in line for this program call
$ MY_NAME="Wade Wilson" python main.py

// Now it can read the environment variable

Hello Wade Wilson from Python

// The env var no longer exists afterwards
$ python main.py

# FastAPI CLI { #fastapi-cli }

**FastAPI <abbr title="command line interface - 命令行接口">CLI</abbr>** 是一个命令行程序，你可以用它来部署和运行你的 FastAPI 应用、管理 FastAPI 项目，等等。

当你安装 FastAPI（例如使用 `pip install "fastapi[standard]"`）时，会附带一个可以在终端中运行的命令行程序。

要在开发环境中运行你的 FastAPI 应用，可以使用 `fastapi dev` 命令：

<div class="termy">

```console
$ <font color="#4E9A06">fastapi</font> dev

    "W",  # pycodestyle warnings
    "F",  # pyflakes
    "I",  # isort
    "B",  # flake8-bugbear
    "C4",  # flake8-comprehensions
    "UP",  # pyupgrade
]
ignore = [
    "E501",  # line too long, handled by black
    "B008",  # do not perform function calls in argument defaults
    "C901",  # too complex
    "W191",  # indentation contains tabs
]

# FastAPI CLI { #fastapi-cli }

**FastAPI <abbr title="command line interface - 명령줄 인터페이스">CLI</abbr>**는 FastAPI 애플리케이션을 서빙하고, FastAPI 프로젝트를 관리하는 등 다양한 작업에 사용할 수 있는 커맨드 라인 프로그램입니다.

FastAPI를 설치하면(예: `pip install "fastapi[standard]"`) 터미널에서 실행할 수 있는 커맨드 라인 프로그램이 함께 제공됩니다.

개발용으로 FastAPI 애플리케이션을 실행하려면 `fastapi dev` 명령어를 사용할 수 있습니다:

<div class="termy">

```console
$ <font color="#4E9A06">fastapi</font> dev

///

## Multiple Workers { #multiple-workers }

You can start multiple workers with the `--workers` command line option:

//// tab | `fastapi`

If you use the `fastapi` command:

<div class="termy">

```console
$ <font color="#4E9A06">fastapi</font> run --workers 4 <u style="text-decoration-style:solid">main.py</u>
