Ruby Gems Support
In this section:
Many types of the Ruby projects make use of the Ruby gems.
- If a project uses the bundler, then all the required gems are taken according to the Gemfile.
- If there is no bundler, IntelliJ IDEA scans all the project files for the calls to Ruby gems, and
produces a set of the required gems.
If for some reason you are not happy with the set of gems defined by IntelliJ IDEA, you can create a Gemfile yourself and specify the gems of your choice.
