Can you post your webpack config?
And what version are you using?

@mrdulin. Thanks, it's a duplicate bug of #51
Maybe you can check over there how you can fix it.

Just need update it with brew.

brew reinstall libpng

[SebastianoF]

To solve the problem I applied the following workaround (that is not optimal, but it is doing the job).

1. locate libpng16.16.dylib in the system with

find /opt -name "libpng16.16.dylib"

that turned out to be under /opt/X11/lib/ in my system.

2. make a symlink of "libpng16.16.dylib" where required:

sudo ln -s /opt/X11/lib/libpng16.16.dylib /usr/local/opt/libpng/lib/libpng16.16.dylib

Note that before step 2, you may need to create the folders /usr/local/opt/libpng/lib/ if not present, with:

sudo mkdir -p /usr/local/opt/libpng/lib/
