ubuntu 16.10 libpng12.so.0: cannot open shared object file

Running on: "image-webpack-loader": "^3.2.0", I always get these errors:

Error in ./images/chat-sprite.png
Module build failed: Error: /home/capaj/git_projects/be/chat-window/node_modules/pngquant-bin/vendor/pngquant: error while loading shared libraries: libpng12.so.0: cannot open shared object file: No such file or directory
 @ ./styles/main.less 6:22437-22473 6:23930-23966 6:28534-28570 6:32673-32709 6:34586-34622 6:36817-36853 6:37912-37948

I researched a bit and tried installing

sudo apt-get install libpng12-0
sudo apt-get install libpng-dev

I eve tried sudo apt install pngquant but no luck. Has anyone been able to make this work on latest ubuntu?

Well. My issue was actually my mistake and might be yours if you are using docker. I was replacing docker’s node_modules folder when running COPY . /usr/app so the local binary was linked to this lib that obviously wasn’t available at the docker machine. Simple adding node_modules to .dockerignore fixed it.

Closing because this is a yarn issue. So when I did:

npm i image-webpack-loader pngquant

it works fine. Seems like yarn is not able to execute the postinstall npm script correctly. @timur-orudzhov are also on yarn? or NPM?
