Middlemanapp: unknown extension

Question

I run from console:

middleman build

and i get

== Unknown Extension: smusher
== Unknown Extension: favicon_maker

my Gemfile

source :rubygems
gem "middleman", "~>3.0.0"
gem "middleman-smusher"
gem "middleman-favicon-maker"

i run bundle install and bundle update. What could the problem be here?

Answer 1

Inside the root of your project should be a config.rb file. Within that file you should add two extensions to the build configuratio:

configure :build do
 activate :smusher
 activate :favicon_maker
end
