OSError when trying to pip install shapely inside docker container

Question

Could not find library geos_c or load any of its variants ['libgeos_c.so.1', 'libgeos_c.so']

using the python:3.5.1 image I am trying to run a container that includes among other things it installs in requirements.txt shapely. When the docker container tries to install shapely I get the above error.

RUN apt-get install libgeos-dev

was something I saw trying to search the issue but that returns unable to locate package libgeos-dev

summary:

expected conditions: including shapely in the requirements.txt file results ins shapely being installed when the docker container is built actual conditions: An error message is recieved during build Could not find library geos_c or load any of its variants ['libgeos_c.so.1', 'libgeos_c.so']

Steps to reproduce:

use docker-compose to build on

Docker-compose.yml:

app:
        build: ${APP_REPO}

Dockerfile:

FROM python:3.5.1-onbuild

Requirements.txt:

shapely

(Simplified to attempt to isolate issues.)

Answer 1

For alpine, just run following Docker command:

RUN apk add --no-cache \
gcc \
libc-dev \
geos-dev \
&& pip install shapely

This will install shapely with all the proper dependencies for geo and C related dependencies for the shapely for alpine
