Ruby on Rails: BlueCloth gem cannot work in production when deployed to heroku -

i'm trying use bluecloth gem in order parse markdown rails app. added gem file:

    gem 'bluecloth' 

in .html.erb views user code

    <%=  bluecloth.new(post.content).to_html.html_safe %> 

to render markdown html. works fine in local dev environment, when push heroku, after running bundle install , restarting app, accessing app generates internal server errors.

i following error in logs:

    actionview::template::error (uninitialized constant actionview::compiledtemplates::bluecloth): 

i include bluecloth in gem file:

source 'https://rubygems.org'  gem 'rails', '3.2.8'  gem 'pg'  group :assets   gem 'sass-rails',   '~> 3.2.3'   gem 'coffee-rails', '~> 3.2.1'   gem 'uglifier', '>= 1.0.3' end  gem 'jquery-rails'  gem 'devise' gem 'bluecloth' 

i have run command bundle install via heroku command line.

thanks help!

it looks manually requiring files. might easier if use bundler require , dont have add require other .rb file. simple this. depending on rails version, here 2 links should out:

rails 2.3

rails 3
