```

Und normalerweise würden Sie diese Paketabhängigkeiten mit `pip` installieren, zum Beispiel:

<div class="termy">

```console
$ pip install -r requirements.txt
---> 100%
Successfully installed fastapi pydantic uvicorn
```

</div>

/// info

## Installation

Create and activate a <a href="https://fastapi.tiangolo.com/virtual-environments/" class="external-link" target="_blank">virtual environment</a> and then install FastAPI:

<div class="termy">

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

---> 100%
```

</div>

**Note**: Make sure you put `"fastapi[standard]"` in quotes to ensure it works in all terminals.

## Example

### Create it

    val groovy = "$groovyGroup:groovy"
    val groovyAnt = "$groovyGroup:groovy-ant"
    val groovyAstbuilder = "$groovyGroup:groovy-astbuilder"
    val groovyConsole = "$groovyGroup:groovy-console"
    val groovyDateUtil = "$groovyGroup:groovy-dateutil"
    val groovyDatetime = "$groovyGroup:groovy-datetime"
    val groovyDoc = "$groovyGroup:groovy-groovydoc"
    val groovyJson = "$groovyGroup:groovy-json"

# First Steps

The simplest FastAPI file could look like this:

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

Copy that to a file `main.py`.

Run the live server:

<div class="termy">

```console
$ <font color="#4E9A06">fastapi</font> dev <u style="text-decoration-style:single">main.py</u>
<font color="#3465A4">INFO    </font> Using path <font color="#3465A4">main.py</font>
