I am getting the following error when I run 'bundle install':
Bundler could not find compatible versions for gem "activesupport":
In Gemfile:
google-drive (>= 0) ruby depends on
middleman-core (>= 3.2.2) ruby depends on
activesupport (~> 3.2.6) ruby
rails (= 4.2.0) ruby depends on
activesupport (4.2.0)
I don't specify a version for the google-drive gemfile, but I do specify gem 'rails', '4.2.0'.
If I fail to specify a rails version, I get a really old version.
