  1. Open your Gemfile located in the root directory of your Rails application.
  2. Look for the line that includes gem ‘sprockets’ (or similar) and ensure it is present.
  3. If the line is missing, add gem ‘sprockets’, ‘3.7.2’ to your Gemfile.
    – If the line is already present, check the version specified. If it’s not ‘3.7.2’, modify it to ‘3.7.2’.
  4. Save the Gemfile and run the following command in your terminal to install the gem:
$ bundle install

Restart your Rails server to ensure the changes take effect.
