No such file or directory "limits.h" when installing Pillow on Alpine Linux

Alpine Linux uses musl libc. You probably need to install musl-dev.

@zakaria answer is correct, but if you stumble upon

fatal error: linux/limits.h: No such file or directory

then you need the package linux-headers (notice the prefix linux before limits.h

apk add linux-headers

python linux python-2.7 alpine

limits.h is located in libc-dev:

apk add libc-dev
