python - 无法在Docker中安装libpulse-dev

Question

我目前正在尝试构建一个docker容器并安装在一些我将用于机器学习的库中。这是我的Dockerfile:

FROM python:3.6-alpine


ENV PATH :$PATH

ADD . /app
WORKDIR /app

#Install dependencies
RUN echo "===> Installing sudo to emulate normal OS behavior..."
RUN apk --update add sudo
RUN apk --update add libxml2-dev libxslt-dev
RUN apk --update add python py-pip openssl ca-certificates
RUN apk --update add --virtual build-dependencies python3-dev libffi-
dev openssl-dev build-base gfortran
RUN apk --update add libpulse-dev
RUN apk --update add py-pip jpeg-dev zlib-dev
RUN apk --update add  swig
RUN apk --update add sshpass openssh-client rsync

#Install python package + requirements.txt
RUN pip install --upgrade pip
RUN  pip install  -r requirements.txt

CMD ["python", "import_emails.py"]

我在libpulse-dev上遇到了一些问题，为了安装Pockersphinx lib，我需要安装它，这是我的TraceBack:

任何想法如何解决这个问题？谢谢。

您可以使用pulseaudio-dev代替libpulse-dev
RUN apk --update add
