Trellis Deploy Error: dyld library not loaded

Hey guys,

Just switched machines for my dev environment. This is probably the first time I’ve done this mid-development.

Everything is running smoothly until I deploy. I am getting this error:

optimizationError: dyld: Library not loaded:
/usr/local/opt/libpng/lib/libpng16.16.dylib
  Referenced from: /Users/masoninthesis/Sites/lyps_v1.1/site/web/app/themes/s

error Command failed with exit code 1.

Full error log here.

But then I got the same error but regarding pngquant, found the temporary solution here:

In webpack.config.optimize.js I changed pngquant: { quality: '65-90', speed: 4 }, to pngquant: null,
