Undefined variable: "$navbar-height". error in Ruby On Rails – SEO

I have just deployed the site and get following error:

Sass::SyntaxError in MainSite#home

Undefined variable: "$navbar-height".

I am not customizing anything and same code works on my local server but not on production server. I have been researching from last 5 days and read more than 10 articles but nothing has worked. Please provide your suggestion and here is the log trace:

    After analyzing the trace records I follow the below steps: Copy local Gemfile and Gemfile.lock to production server and run the below command:

    $ rvm use 2.1.3
$ rvm gemset empty
$ bundle install

    Are you using Bootstrap? if so then which one?
    If you are using bootstrap gem then omit all bootstrap gem and use files in assets.

    A general point: If it is working when environment is set to development, but not when set to production then it’s an error caused due to the project being configured differently. In rails, the production configuration includes a bunch of optimisations such as how it builds the assets, or doesn’t within production.

    Beyond this, I would start to look first at what is different in their deployments. Are they both using the same gems (you can compare the Gemfile.lock), and check that there is nothing that is on your local machine that has not been checked into git/svn.

    Also look at whether your system environments are similar (you can see why folks like containers/docker). Such as are you developing on mac but running on a windows host in production.

    UPDATE: The above is general advice, below is advise based on the error.

    Looking the rails_admin gem, you might want to look through the troubleshooting for bootstrap issues here. Let me know if none of those solutions fix your issue

    You need to precompile the assets check the development.rb file and include the all sass file

    config.assets.precompile += %w( rails_admin/base/theming.scss );

    add this line to development.rb file
