django.core.exceptions.不正确配置:找不到 GDAL 库

Question

我正在尝试在docker中使用gis：

这是 django 的Dockerfile：

FROM python:3.6-alpine
ENV PYTHONUNBUFFERED 1
RUN apk update 
# psycopg2 dependencies
&& apk add --virtual build-deps gcc python3-dev musl-dev 
&& apk add postgresql-dev 
# Pillow dependencies
&& apk add jpeg-dev zlib-dev freetype-dev lcms2-dev openjpeg-dev tiff-dev tk-dev tcl-dev 
# CFFI dependencies
&& apk add libffi-dev py-cffi 
# Translations dependencies
&& apk add gettext 
# https://docs.djangoproject.com/en/dev/ref/django-admin/#dbshell
&& apk add postgresql-client

# ADD PostGIS here
# POSTGIS dependencies
ENV POSTGIS_VERSION 2.4.4
ENV POSTGIS_SHA256 0dff4902556ad45430e2b85dbe7e9baa758c6eb0bfd5ff6948f478beddd56b67

RUN set -ex 

&& apk add --no-cache --virtual .fetch-deps 
ca-certificates 
openssl 
tar 

&& wget -O postgis.tar.gz "https://github.com/postgis/postgis/archive/$POSTGIS_VERSION.tar.gz" 
&& echo "$POSTGIS_SHA256 *postgis.tar.gz" | sha256sum -c - 
&& mkdir -p /usr/src/postgis 
&& tar 
--extract 
--file postgis.tar.gz 
--directory /usr/src/postgis

&& rm postgis.tar.gz 

&& apk add --no-cache --virtual .build-deps 
autoconf 
automake

libtool 
libxml2-dev 
make 
perl 

# add libcrypto from (edge:main) for gdal-2.3.0
&& apk add --no-cache --virtual .crypto-rundeps

&& apk add --no-cache --virtual .build-deps-testing

&& cd / 
&& rm -rf /usr/src/postgis 
&& apk del .fetch-deps .build-deps .build-deps-testing
#  && apk del .fetch-deps .build-deps .build-deps-testing
# END POSTGIS Changes

# Requirements are installed here to ensure they will be cached.
COPY ./requirements /requirements
RUN pip install -r /requirements/local.txt
COPY ./compose/production/django/entrypoint /entrypoint
RUN sed -i 's/r//' /entrypoint
RUN chmod +x /entrypoint
COPY ./compose/local/django/start /start
RUN sed -i 's/r//' /start
RUN chmod +x /start

COPY ./compose/local/django/celery/flower/start /start-flower
RUN sed -i 's/r//' /start-flower
RUN chmod +x /start-flower
WORKDIR /app
ENTRYPOINT ["/entrypoint"]

这是我对帖子Dockerfile：

FROM mdillon/postgis 
COPY ./compose/production/postgres/maintenance /usr/local/bin/maintenance
RUN chmod +x /usr/local/bin/maintenance/*
RUN mv /usr/local/bin/maintenance/* /usr/local/bin 
&& rmdir /usr/local/bin/maintenance

我做错了什么？

Answer 1

只需要删除这一行Dockerfile：&& apk del .fetch-deps .build-deps .build-deps-testing

我还没有弄清楚，但很可能它会删除我上面添加的所有软件包。

Answer 2

我不确定，但通过阅读 debian 软件包部分，看起来您不像是在安装gdal-dev或libgdal-dev，名称取决于您的发行版，但您明白了。
