Sprockets cannot precompile chartkick

Question

I am using chartkick (added gem 'chartkick' in my Gemfile) and have defined it in my views/layouts/application.html.erb like this:

  <%= javascript_include_tag "//www.google.com/jsapi", "chartkick" %>

But on running the server, it results in an error:

Sprockets::Rails::Helper::AssetNotPrecompiled in Main#index
chartkick.js

I am using rails 5.0.7. I tried following the way mentioned in https://chartkick.com/#rails-5-sprockets. But still, it results in the same error.

Can you help me in finding what I'm doing wrong?

Or If anyone could tell me what direction should I head to, that would be awesome as well.

UPDATE: Adding config.assets.check_precompiled_asset = false fixes the issues. But, adding this line means it will not verify/check precompiled_assets. Which is not a good thing, is it?
