Uninitialized Constant TZInfo::InvalidTimezoneIdentifier (NameError) - Rails 4

Question

I\'m in the process of upgrading a Rails 3.2 app to Rails 4.1. Whenever I try to start the console or server though, I come across this error:

C:/Ruby200/lib         


        

Answer 1

Requiring the tzinfo gem before initializing the app in environment.rb fixes the issue for me. Doesn't really explain everything, but seems to work

# adding this fixes the issue
require 'tzinfo'

# Initialize the rails application
RailsApp::Application.initialize!

Edit: Seems this was a problem with Rails: https://github.com/rails/rails/issues/13553

Answer 2

This worked for me:

gem uninstall tzinfo
#select 'All versions'
gem install tzinfo
rails c
