python - Dockerfile 努力安装 Python Geopandas 模块

Question

我有一个 dockerfile，我试图在其中使用所需的 python 模块构建一个容器。
请参阅下面的 dockerfile 以了解我尝试安装的方式和模块:

FROM ubuntu:bionic

ENV ROOTDIR /usr/local/
ENV GDAL_VERSION 2.4.1
ENV OPENJPEG_VERSION 2.3.0
ENV CURL_CA_BUNDLE /etc/ssl/certs/ca-certificates.crt

# Load assets
WORKDIR $ROOTDIR/

ADD http://download.osgeo.org/gdal/${GDAL_VERSION}/gdal-${GDAL_VERSION}.tar.gz $ROOTDIR/src/
ADD https://github.com/uclouvain/openjpeg/archive/v${OPENJPEG_VERSION}.tar.gz $ROOTDIR/src/openjpeg-${OPENJPEG_VERSION}.tar.gz

    cmake

# Compile and install OpenJPEG
RUN cd src && tar -xvf openjpeg-${OPENJPEG_VERSION}.tar.gz && cd openjpeg-${OPENJPEG_VERSION}/ \
    && mkdir build && cd build \
    && cmake .. -DCMAKE_BUILD_TYPE=Release -DCMAKE_INSTALL_PREFIX=$ROOTDIR \
    && make && make install && make clean \
    && cd $ROOTDIR && rm -Rf src/openjpeg*

# Compile and install GDAL

    && ./configure --with-python --with-spatialite --with-pg --with-curl --with-openjpeg \
    && make -j $(nproc) && make install && ldconfig \
    && apt-get update -y \
    && cd $ROOTDIR && cd src/gdal-${GDAL_VERSION}/swig/python \

      python3-dev \
    && cd $ROOTDIR && rm -Rf src/gdal*


# install Vim
RUN apt-get -y install vim

# Install Pip3 and required python modules
RUN apt-get -y install python3-pip

RUN pip3 install rasterio &&\
    pip3 install rdp &&\
    pip3 install gdal2tiles&&\
    pip3 install awscli &&\
    pip3 install pandas &&\
    pip3 install boto3 &&\
    pip3 install requests &&\
    pip3 install shapely &&\
    pip3 install geopandas &&\   
    pip3 install math 

但是，它似乎已经到了 geopandas 模块，然后我遇到了这个错误:

Collecting pyproj>=2.2.0 (from geopandas)
  Downloading https://files.pythonhosted.org/packages/2c/12/7a8cca32506747c05ffd5c6ba556cf8435754af0939906cbcc7fa5802ea3/pyproj-3.0.1.tar.gz (168kB)
    Complete output from command python setup.py egg_info:
    ERROR: Cython.Build.cythonize not found. Cython is required to build pyproj.

    ----------------------------------------
Command "python setup.py egg_info" failed with error code 1 in /tmp/pip-build-vtfufrfs/pyproj/

有没有人知道如何克服这个问题？

Answer 1

您的 Python3 环境缺少 Cython 包。添加行 pip3 install cython在 pip3 install geopandas 之前线。
您还需要升级您的 pip 版本。
并且直接从 Python3 解释器而不是 pip3 包装器使用 pip 更方便。所以我会去重构你最后的RUN像这样阻止:

RUN \
   python3 -m pip install --upgrade pip \
   && python3 -m pip install \
        cython \
        rasterio \
        rdp \
        gdal2tiles \
        awscli \
        pandas \
        boto3 \
        requests \
        shapely \
        geopandas
