如何添加libpcre3-dev和libpcre3到docker镜像python:3.9-alpine3.13当没有这样

Question

我需要PCRE支持我的uwsgi运行。因此，我计划将libpcre3和libpcre3-dev添加到我的docker中。

这是我的Dockerfile设置:

FROM python:3.9-alpine3.13
ENV PYTHONUNBUFFERED 1
COPY ./requirements.txt /tmp/requirements.txt
COPY ./requirements.dev.txt /tmp/requirements.dev.txt
COPY ./scripts /scripts
COPY ./app /app
WORKDIR /app
EXPOSE 8000
ARG DEV=false
RUN python -m venv /py && 
/py/bin/pip install --upgrade pip && 
apk add --update --no-cache postgresql-client jpeg-dev libpcre3-dev libpcre3 && 
apk add --update --no-cache --virtual .tmp-build-deps 
build-base postgresql-dev musl-dev zlib zlib-dev linux-headers && 
/py/bin/pip install -r /tmp/requirements.txt && 
if [ $DEV = "true" ]; then /py/bin/pip install -r /tmp/requirements.dev.txt ; 
fi && 
rm -rf /tmp && 
apk del .tmp-build-deps && 
adduser 
--disabled-password 
--no-create-home 
django-user && 
mkdir -p /vol/web/media && 
mkdir -p /vol/web/static && 
chown -R django-user:django-user /vol && 
chmod -R 755 /vol && 
chmod -R +x /scripts
ENV PATH="/scripts:/py/bin:$PATH"

我得到的错误是:

> [recipe-app-api-app 7/7] RUN python -m venv /py &&     /py/bin/pip install --upgrade pip &&     apk add --update --no-cache postgresql-client jpeg-dev libpcre3-dev libpcre3 &&     apk add --update --no-cache --virtual .tmp-build-deps         build-base postgresql-dev musl-dev zlib zlib-dev linux-headers &&     /py/bin/pip install -r /tmp/requirements.txt &&     if [ false = "true" ]; then /py/bin/pip install -r /tmp/requirements.dev.txt ;     fi &&     rm -rf /tmp &&     apk del .tmp-build-deps &&     adduser         --disabled-password         --no-create-home         django-user &&     mkdir -p /vol/web/media &&     mkdir -p /vol/web/static &&     chown -R django-user:django-user /vol &&     chmod -R 755 /vol &&     chmod -R +x /scripts:

所以我可以做些什么来添加下面的包吗?

我已经尝试用不同的名字安装，并在网上搜索了很多，但仍然没有一个想法添加这些包。

最后我可以通过安装β.εηοιτ提到的pcre-dev包来运行我的uwsgi。βε on无法在Alpine上安装uwsgi

所以，这是我最终的Dockerfile设置:

FROM python:3.9-alpine3.13
ENV PYTHONUNBUFFERED 1
COPY ./requirements.txt /tmp/requirements.txt
COPY ./requirements.dev.txt /tmp/requirements.dev.txt
COPY ./scripts /scripts
COPY ./app /app
WORKDIR /app
EXPOSE 8000
ARG DEV=false
RUN python -m venv /py && 
/py/bin/pip install --upgrade pip && 
apk add --update --no-cache postgresql-client jpeg-dev pcre-dev && 
apk add --update --no-cache --virtual .tmp-build-deps 
build-base postgresql-dev musl-dev zlib zlib-dev linux-headers && 
/py/bin/pip install -r /tmp/requirements.txt && 
if [ $DEV = "true" ]; then /py/bin/pip install -r /tmp/requirements.dev.txt ; 
fi && 
rm -rf /tmp && 
apk del .tmp-build-deps && 
adduser 
--disabled-password 
--no-create-home 
django-user && 
mkdir -p /vol/web/media && 
mkdir -p /vol/web/static && 
chown -R django-user:django-user /vol && 
chown -R django-user:django-user ./* && 
chmod -R 755 /vol && 
chmod -R +x /scripts
ENV PATH="/scripts:/py/bin:$PATH"
