That error looks bad but it's actually okay! It's an optional dependency failing to compile probably because the native module is incompatible with the version of node you're using. To fix this, it'll probably require a nunjucks dependency update.

[tkane2000]

Thanks for the quick response! I didn't realize there was such a thing as optional dependencies. I see it's this one:
wintersmith-nunjucks -> nunjucks -> chokidar -> "fsevents": "pipobscure/fsevents#7dcdf9fa3f8956610fd6f69f72c67bace2de7138"

I wasn't able to find much info on pipobscure/fsevents, so I don't think it's worth changing my nodejs version to fix it. I'll just live with it, since as you said, it doesn't actually break anything.

It may be optional, but it seems to prevent anything else from installing as well:

  starting preview server
  using config file: /Users/chetcorcos/code/www.affirm.com/config.json

  error Error loading plugin 'wintersmith-nunjucks': Cannot find module '../node_modules/wintersmith/node_modules/marked'

[jbuck]

That's weird, that looks like the wintersmith install didn't finish correct. See how the marked module is a sub-dependency? Can you re-run npm install for wintersmith?
