*** uWSGI compiling server core ***
Any idea what could cause this? I'm installing the following dependencies beforehand:
RUN apk --update add \
bash \
python \
python-dev \
py-pip \
gcc \
zlib-dev \
git \
linux-headers \
build-base \
musl \
musl-dev \
memcached \
libmemcached-dev

Answer 1

I found this on a GitHub thread. Modified it a bit and works perfectly fine for me on Python 3.5
apk add python3-dev build-base linux-headers pcre-dev
pip install uwsgi

Answer 2

Unfortunately the latest release of uwsgi does not support musl, a glibc alternative that alpine and a couple other distros use. Uwsgi will not build with musl when the ugreen plugin is included (see https://github.com/unbit/uwsgi/pull/522), so you still cannot pip install uwsgi. However, if you build uwsgi with the environment variable UWSGI_PROFILE=corethe build should succeed; but if will fail at runtime due to the issues solved here (https://github.com/unbit/uwsgi/pull/1210). This probably grim news -- I know it was for me -- but at least it looks like the uwsgi team is taking time to address its issues running on musl. Hopefully it will work in the next release.

Answer 3

This is a bit old and this was not exactly the case of the OP. In my case upgrading the version on requirements.txt to uwsgi==2.0.17.1 worked, as I found here.

Answer 4

have you tried
http://github.com/unbit/uwsgi/archive/uwsgi-2.0.zip
in your requirements.txt ?
you'll need the pcre-dev package installed

Answer 5

Upgrading uWSGI from 2.0.14 to 2.0.19.1 did the trick for me.
