IntelliJ IDEA 2022.2 Help

Supported versions of Ruby-related technologies

This page lists the versions of Ruby and Ruby-related technologies with tailored support in the Ruby plugin.

Each technology can be under one of the following support policies:

  • Supported

  • Not maintained: if the technology was previously supported in IntelliJ IDEA, but there wouldn't be any further improvements and the feature might be removed in upcoming releases

  • Not supported: if the support for a particular technology was retired

Ruby

To work with the Ruby programming language, you need to download and install the required Ruby distribution. IntelliJ IDEA automatically detects interpreters installed on a local machine and maintained by version managers.
