Sage 9 error with mozjpeg when running build:production

When I run yarn run build:production I get the following error:

unity$ yarn run build:production

So… does this mean I need to install libpng as a dependency?

For reference, the modifications I made to Sage 9 are as follows: removed Bootstrap, added Materialize-CSS and font-awesome. I don’t think I’ve touched anything that has to do with image optimization.

Thanks for your help!

Assure libpng is installed and up to date with brew.

If it is, try relinking it with:

brew unlink libpng && brew link libpng

If all else fails: brew reinstall libpng
