Can't install via pip in Alpine Linux 3.11

[3id010nCD]

Trying to install pdftotext==2.1.4 version.
There is a poppler package in Alpine repo, which includes poppler-dev, poppler-doc, poppler-glib, poppler-utils as subpackages...
My Dockerfile:

# precompiled python wheels for pandas and numpy => faster docker build
FROM nickgryg/alpine-pandas
# install dependencies
# the lapack package is only in the community repository
RUN echo "http://dl-4.alpinelinux.org/alpine/edge/community" >> /etc/apk/repositories
# Install dependencies
RUN apk add --no-cache --virtual .build-deps \
    gfortran \
    musl-dev \
    g++
RUN ln -s /usr/include/locale.h /usr/include/xlocale.h
RUN apk --update add --no-cache \
    freetype-dev \
    lapack-dev \
    gcc \
    poppler

COPY . /app
WORKDIR /app
RUN pip install -r requirements.txt

# removing dependencies to limit the size of your image
RUN apk del .build-deps

Output with error:

Maybe I need some additional packages?

You also need to install the poppler-dev alpine package

Thank you! After installing poppler-dev, I could install correctly pdftotext python module. I, apparently, misunderstood official alpine repo page for poppler package. I thought poppler package already contains poppler-dev in Sub Packages...

@jalan thank you. It saved me a lot of time! What do you think about presenting full recommended docker Image in docs?

I have this one

FROM python:3.7-alpine
WORKDIR /code
ENV FLASK_APP index.py
ENV FLASK_RUN_HOST 0.0.0.0
COPY requirements.txt requirements.txt
RUN apk add --no-cache --virtual \
      .build-deps \
      gcc \
      musl-dev \
      linux-headers \
      pkgconfig poppler-utils \
      build-base \
      alpine-sdk \
      poppler-dev \
     && pip install -r requirements.txt 
COPY . .
CMD ["flask", "run"]

Because of I connecting this with flask, but you better know which dependencies are really important.

@gustawdaniel I like the idea here. I created #71 to track it, so I don't forget. Thanks
