我正在尝试为一个小型 python web 项目编写 Dockerfile,但依赖项有问题。我一直在互联网上进行一些搜索,它说 Librosa 库需要 libsndfile 才能正常工作,所以我尝试使用 apt-get install libsndfile1 安装它。 (我也试过 libsndfile-dev,...)。但是,它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

但是,当我尝试构建并运行它时,发生了此错误:

最佳答案

对于那些来这篇文章寻找解决方案的人。我的解决方法是在这部分之后安装 libsndfile:

FROM python:3.6-buster AS run

COPY --from=build /opt/venv /opt/venv

COPY . .

ENV PATH="/opt/venv/bin:$PATH"

这将是:
FROM python:3.6-buster AS run

COPY --from=build /opt/venv /opt/venv

COPY . .

ENV PATH="/opt/venv/bin:$PATH"

RUN apt-get update -y && apt-get install -y --no-install-recommends build-essential gcc \
libsndfile1

RUN gunicorn -b :5000 --access-logfile - --error-logfile - app:app
