我正在尝试为一个小的Python Web项目编写Dockerfile，但是依赖关系出了点问题。我在互联网上进行了一些搜索，得知Librosa库需要libsndfile才能正常工作，因此我尝试使用apt-get install libsndfile1（我也尝试过libsndfile-dev等）进行安装。然而，这似乎并没有解决我的问题。
这是我的Dockerfile的样子：
FROM python:3.6-buster as build
ENV STATIC_URL /static
ENV STATIC_PATH /var/www/app/static
WORKDIR /var/www/
RUN python -m venv /opt/venv
ENV PATH="/opt/venv/bin:$PATH"
COPY requirements.txt .
RUN pip install -r requirements.txt
RUN pip install gunicorn
RUN apt-get update -y && apt-get install -y --no-install-recommends build-essential gcc \
libsndfile1
FROM python:3.6-buster AS run
COPY --from=build /opt/venv /opt/venv
COPY . .
ENV PATH="/opt/venv/bin:$PATH"
RUN gunicorn -b :5000 --access-logfile - --error-logfile - app:app
然而，当我尝试构建和运行它时，发生了这个错误：
