Ruby on Rail running apache show index of when accessing the site

I have recently updated to Apache 2.4, and I am using Ruby on Rail to run my application. Following the upgrade, the site shows a content as seen in the image below, and the error on the log file shows this error message. I have tried using the ‘Bundle Install’ and checked the permission but that hasn’t helped. Any advice would be greatly appreciated. Thanks

    This error shows a problem with the shared objects. You probably updated MySQL/MariaDB libraries with Apache and new libraries are incompatible with your mysql2 gem build. The solution is simple:

    First, ensure you are using the ruby-2.0.0-p353@hroot RVM environment.

    Then, execute the following command:

    gem install mysql2 --version 0.3.14

    This should rebuild your mysql2 gem for the new MySQL/MariaDB client libraries on your system.

    this isn’t the answer anyway but another method to run ruby (in my case Windows 10 ; if you use another OS try to find out how to modify inside index.php the ruby starter)
    i post here an alternative method to use apache + php +… and ruby
