You can clone with
# If you precompile assets before deploying to production, use this line
# Bundler.require *Rails.groups(:assets => %w(development test))
# If you want your assets lazily compiled in production, use this line
Bundler.require(:default, :assets, Rails.env)
for those that are troubleshooting this, this snippet of code needs to be updated in application.rb
+1 thanks for this.
