我如何在docker中安装lxml
我想在docker中部署我的python项目，因为项目需要lxml，所以我在requirments.txt中写了lxml>=3.5.0 。 这是我的dockfile：
FROM gliderlabs/alpine:3.3 RUN set -x \ && buildDeps='\ python-dev \ py-pip \ build-base \ ' \ && apk --update add python py-lxml $buildDeps \ && rm -rf /var/cache/apk/* \ && mkdir -p /app ENV INSTALL_PATH /app WORKDIR $INSTALL_PATH COPY requirements-docker.txt ./ RUN pip install -r requirements.txt COPY . . RUN apk del --purge $buildDeps ENTRYPOINT ["celery", "-A", "tasks", "worker", "-l", "info", "-B"]
当我将它部署到docker时，我得到了这个：
********************************************************************************* Could not find function xmlCheckVersion in library libxml2. Is libxml2 installed? ********************************************************************************* error: command 'gcc' failed with exit status 1 ---------------------------------------- Rolling back uninstall of lxml
我虽然是因为'python-dev'和'python-lxml'，然后我编辑了这样的dockfile：
WORKDIR $INSTALL_PATH COPY requirements-docker.txt ./ RUN apt-get build-dev python-lxml RUN pip install -r requirements.txt
它没有工作，我得到了另一个错误：
---> Running in 73201a0dcd59 /bin/sh: apt-get: not found
我如何正确地在docker中安装lxml？ 谢谢
我添加了RUN apk add --update --no-cache g++ gcc libxslt-dev==1.1.29-r0之前RUN pip install -r requirements.txt和它的工作。

下载apk并安装它
RUN wget http://nl.alpinelinux.org/alpine/edge/main/x86_64/py-lxml-3.4.0-r0.apk -O /var/cache/apk/py-lxml.apk RUN apk add --allow-untrusted /var/cache/apk/py-lxml.apk
