rails -g polymer:install ERROR

After adding gem to the Gemfile and running bundle, when trying to run rails g polymer:install I'm getting this error block:

This prevents me from using this gem of course. Hopefully see a fix soon? I'm an experienced Polymer dev, but a newbie for Rails. Looking forward to using this.

Also, when using 1.0, I get a bundle error:

Bundler could not find compatible versions for gem "sprockets":
  In Gemfile:
    polymer-rails (~> 1.0) ruby depends on
      sprockets (< 3.0.0) ruby

    sass-rails (~> 5.0) ruby depends on
      sprockets (3.2.0)

Using rails 4.2.1 to build my app.

You can try bundle show | grep sprocket to see if you have sprockets installed.

hey @caseybaggz polymer-rails doesn't work with sprockets 3.x.x yet. I'm planning to make needed changes soon, but for now to make it work you can specify gem 'sprockets', '2.11.3' in your Gemfile and run bundle update sprockets

@alchapone that fixed it! Great man. Looking forward to seeing this gem stay healthy and active. Great work bringing the Polymer goodness to rails. :+1:
