ChefDK has a number of applications it ships that all have different 
dependencies. Though you saw this problem with the `chef` gem, it could also 
happen with RSpec, since the various apps in ChefDK are on different versions 
of RSpec. Furthermore, it’s completely possible for you to install gems which 
might conflict with the applications packaged in ChefDK (using `chef gem 
install`). For this reason, most executables in ChefDK are generated with the 
appbundler tool, which locks all dependencies to known working versions.

ChefSpec is a tricky case because it’s more or less a plugin for RSpec, but 
we’re not installing RSpec itself via the appbundler process. In the future 
we plan to wrap ChefSpec in a `chef test` command:

For now you can use bundler to lock your gem versions for RSpec/ChefSpec to a 
compatible set. Initializing your shell via `chef shell-init` makes this a 
lot easier.
