不能在Docker中安装libpulse-dev
我目前正在试图build立一个docker集装箱，并安装在一些图书馆，我将用于机器学习。 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"] 我得到了libpulse-dev的一些问题，我需要安装Pockersphinx库，这是我的TraceBack：

任何想法如何解决这个问题？ 谢谢。
