Regression from version 4.1.0 to 4.2.0, install failing at mozjpeg

Version 4.1.0 installs and works perfectly. 🥇

However trying to install version 4.2.0 on Linux (Ubuntu 16.04) results in the following error:

Message:

@1000ch after installing that it does give a different error message:

If 4.2.0 introduces new dependencies it should’ve been a major. Besides that the instructions in the readme: apt-get install -y libjpeg libpng don’t work, both packages are unable to locate. That said, version 4.1.0 of this module is still working fine.

For anyone else searching here, if libpng16 isn’t available on your distribution (I’m using Debian 8/jessie), you’ll need to build it yourself. I’m using a Docker image for deploys, so I installed it with these commands:

# Install dependencies for gulp-image
RUN apt-get update -q \
	&& apt-get install -qy libjpeg-dev \
	&& curl -L https://sourceforge.net/projects/libpng/files/libpng16/1.6.35/libpng-1.6.35.tar.gz/download > libpng-1.6.35.tar.gz \
	&& tar -xzvf libpng-1.6.35.tar.gz \
	&& cd libpng-1.6.35 \
	&& ./configure \
	&& make \
	&& make install \
	&& ldconfig
