What are the default Mac OSX 10.11 aircraft?

Question

I tried to learn Ruby on Rails and followed the tutorial. However, I think I missed the part, and I can’t go to the next step in the tutorial, so I plan to remove things, including the gems I have set, and start all over again.

I installed Ruby with Homebrew because people say it’s better not to mess with Ruby, which comes with macOS. Then I deleted it again using brew uninstall ruby.

After that, I started gem listand it worked:

*** LOCAL GEMS ***

- bigdecimal (1.2.0)
- builder (3.2.2)
- CFPropertyList (2.2.8)
- io-console (0.4.2)
- json (1.7.7)
- libxml-ruby (2.6.0)
- minitest (4.3.2)
- nokogiri (1.5.6)
- psych (2.0.0)
- rake (0.9.6)
- rdoc (4.0.0)
- sqlite3 (1.3.7)
- test-unit (2.0.0.0)
- thor (0.19.1)

What gems (if any) that come with MacOS Ruby?
