can't install simple_captcha produces uninitialized constant Sprockets::Helpers

Question

I have included the simple_captcha gem as instructed on their site:

gem 'simple_captcha', :git => 'git://github.com/galetahub/simple-captcha.git'

I have then run bundler to install it.

Finally when I go to run the following command I get an error:

 rails generate simple_captcha

.rvm/gems/ruby-1.9.3-p327@eapi4/bundler/gems/simple-captcha-e99cc7e8bf6b/lib/simple_captcha/form_builder.rb:7:in `included': uninitialized constant Sprockets::Helpers (NameError)

I've searched on the web and can't find any other users with this problem.

Any help appreciated

Answer 1

They say in this pull request that the plugin doesn't support rails 4, You can download their branch and try it out.

Looking at the diff it shows your problem

-      base.send(:include, Sprockets::Helpers::RailsHelper)
-      base.send(:include, Sprockets::Helpers::IsolatedHelper)
+      base.send(:include, Sprockets::Rails::Helper)
