I got this error while trying to start a new Ruby on Rails project:

D:/friends/config/environment.rb:5:in `<main>'

Caused by:

The web told me to ensure tzinfo-data was in the Gemfile and then use bundle install, and no matter how many time I ensured it was there, this error has repeatedly occured! One thing I noticed is that whenever I use the rails new command, it automatically adds the platforms to the Gemfile. Why is this happening?
