如何在 Alpine 3.8 上安装 libvips？

Question

I try to install vips-dev package to alpine linux 3.8. But get following error:

docker run -it --rm alpine:3.8 /bin/sh -c "apk add --update --no-cache --repository http://dl-3.alpinelinux.org/alpine/edge/testing vips-dev"

fetch http://dl-3.alpinelinux.org/alpine/edge/testing/x86_64/APKINDEX.tar.gz
fetch http://dl-cdn.alpinelinux.org/alpine/v3.8/main/x86_64/APKINDEX.tar.gz
fetch http://dl-cdn.alpinelinux.org/alpine/v3.8/community/x86_64/APKINDEX.tar.gz
ERROR: unsatisfiable constraints:
  pc:fftw3 (missing):
    required by: vips-dev-8.7.4-r1[pc:fftw3] vips-dev-8.7.4-r1[pc:fftw3] vips-dev-8.7.4-r1[pc:fftw3]

How to solve it?

Answer 1

This is a known packaging issue of vips-dev on edge/testing :
https://bugs.alpinelinux.org/issues/9561

As a workaround, make sure to add both edge/main and edge/testing repositories to your apk command:

sudo docker run -it --rm alpine:3.8 /bin/sh -c "apk add --update --no-cache --repository http://dl-3.alpinelinux.org/alpine/edge/testing --repository http://dl-3.alpinelinux.org/alpine/edge/main vips-dev"

Update, 30/5/19:

vips-dev has moved from the edge/testing branch to edge/community , and updated to version 8.8.0-r0. Therefore, the updated command line is:

sudo docker run -it --rm alpine:3.8 /bin/sh -c "apk add --update --no-cache --repository http://dl-3.alpinelinux.org/alpine/edge/community --repository http://dl-3.alpinelinux.org/alpine/edge/main vips-dev"
