## Dependencies errors and return values { #dependencies-errors-and-return-values }

You can use the same dependency *functions* you use normally.

### Dependency requirements { #dependency-requirements }

They can declare request requirements (like headers) or other sub-dependencies:

{* ../../docs_src/dependencies/tutorial006_an_py39.py hl[8,13] *}

### Raise exceptions { #raise-exceptions }

1. 공식 파이썬 베이스 이미지에서 시작합니다.

2. 현재 워킹 디렉터리를 `/code`로 설정합니다.

    여기에 `requirements.txt` 파일과 `app` 디렉터리를 위치시킬 것입니다.

```

├── Dockerfile
├── main.py
└── requirements.txt
```

Dann müssten Sie nur noch die entsprechenden Pfade ändern, um die Datei im `Dockerfile` zu kopieren:

```{ .dockerfile .annotate hl_lines="10  13" }
FROM python:3.9

WORKDIR /code

COPY ./requirements.txt /code/requirements.txt

RUN pip install --no-cache-dir --upgrade -r /code/requirements.txt

# (1)!
COPY ./main.py /code/

        enable-cache: true

            requirements**.txt
            pyproject.toml
    - name: Install GitHub Actions dependencies
      run: uv pip install -r requirements-github-actions.txt
    - name: Label Approved
      run: python ./scripts/label_approved.py
      env:
        TOKEN: ${{ secrets.GITHUB_TOKEN }}

        uses: astral-sh/setup-uv@v7
        with:
          version: "0.4.15"
          enable-cache: true

            pyproject.toml
      - name: Install GitHub Actions dependencies
        run: uv pip install -r requirements-github-actions.txt
      - name: Update Topic Repos
        run: python ./scripts/topic_repos.py
        env:

```

Entonces solo tendrías que cambiar las rutas correspondientes para copiar el archivo dentro del `Dockerfile`:

```{ .dockerfile .annotate hl_lines="10  13" }
FROM python:3.9

WORKDIR /code

COPY ./requirements.txt /code/requirements.txt

RUN pip install --no-cache-dir --upgrade -r /code/requirements.txt

# (1)!
COPY ./main.py /code/

---> 100%
```

### Install from `requirements.txt` { #install-from-requirements-txt }

If you have a `requirements.txt`, you can now use it to install its packages.

//// tab | `pip`

<div class="termy">

```console
$ pip install -r requirements.txt
---> 100%
```

</div>

////

//// tab | `uv`
