For Linux Web Hosting and Managed Dedicated Server packages
The Ruby programming language is available in many 1&1 IONOS Web Hosting and Managed Server packages.
You can use the following Secure Shell (SSH) command to display the installed Ruby version in your webspace:
$ ruby -v
Please note: The Ruby on Rails framework is not available in our Webhosting or Managed Server packages. For this we recommend using of a Dedicated Server with a Linux or Windows Operating System.
