<div class="termy">

```console
$ cd ~/code/prisoner-of-azkaban

$ python main.py

// Error importando sirius, no está instalado 😱
Traceback (most recent call last):
    File "main.py", line 1, in <module>
        import sirius
```

</div>

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

---> 100%
```

</div>

**Note**: 请确保把 `"fastapi[standard]"` 用引号包起来，以保证在所有终端中都能正常工作。

## 示例 { #example }

### 创建 { #create-it }

创建文件 `main.py`，内容如下：

```Python
from fastapi import FastAPI

app = FastAPI()


@app.get("/")
def read_root():
    return {"Hello": "World"}


@app.get("/items/{item_id}")

**Hinweis**: Stellen Sie sicher, dass Sie `"fastapi[standard]"` in Anführungszeichen setzen, damit es in allen Terminals funktioniert.

## Beispiel { #example }

### Erstellung { #create-it }

Erstellen Sie eine Datei `main.py` mit:

```Python
from fastapi import FastAPI

app = FastAPI()


@app.get("/")
def read_root():
    return {"Hello": "World"}


@app.get("/items/{item_id}")

### `root_path` 제공하기 { #providing-the-root-path }

이를 달성하려면 다음처럼 커맨드 라인 옵션 `--root-path`를 사용할 수 있습니다:

<div class="termy">

```console
$ fastapi run main.py --forwarded-allow-ips="*" --root-path /api/v1

```

</div>
