Getting this error upon creating users:

`oxipng worker: `oxipng`not found; please provide proper binary or disable this worker (--no-oxipng argument or`:oxipng =\> false` through options)`

Then after that it begins creating posts.

- Could this be why attachments aren’t appearing in Discourse?
- Where should oxipng be installed?

Update: I’m confused why I’m getting this oxipng error. I can’t find anything about it anywhere in Discourse, and I’m experiencing this issue only upon running the smf2 import script. Could it possibly be related to this?
