Putting require 'spec_helper' results in Bad URI error

I did rails generate rspec:install, ran rake spec and it works just fine.

However, when I create a new spec file and add require 'spec_helper', I get the following error.

rvm/rubies/ruby-2.1.4/lib/ruby/2.1.0/uri/common.rb:176:in `split': bad URI(is not URI?):  (URI::InvalidURIError)

Anyone know what might be the issue?

EDIT: Also, when I run rake db:schema:load RAILS_ENV=test I get

URI::InvalidURIError: bad URI(is not URI?):
