Also, you should move off WEBrick for Heroku, thats a dev server. Try using Unicorn https://devcenter.heroku.com/articles/rails-unicorn

I have a simple Rails app that works fine on localhost (Mac OS X), but when I deploy it to Heroku I see a page with this error:
Application Error An error occurred in the application and your page could not be served. Please try again in a few moments. If you are the application owner, check your logs for details.
I don't really know what I'm doing here; I can't make any sense whatsoever of the output from
heroku logs

The line
no such file to load -- nokogiri
looks like it might be the culprit but I can't figure out how to fix it; I've tried runningbundle install
,bundle update
, restarting heroku withheroku restart
and all kinds of other guess-based solutions that I can't remember now but it's still not working!Here's my Gemfile:
