I’m using Rails 4.2.7. I downloaded an example that evidently requires me to use Ruby 2.1.6 rather than the Ruby 2.3.0 version I had installed …
localhost:lti_tool_provider_example-master davea$ bundle install
Your Ruby version is 2.3.0, but your Gemfile specified 2.1.6
So that’s what I did. However after installing Ruby 2.1.6, now “bundle install” doesn’t work …
localhost:lti_tool_provider_example-master davea$ rvm install ruby-2.1.6
Warning! PATH is not properly set up, '/Users/davea/.rvm/gems/ruby-2.3.0/bin' is not at first place,
usually this is caused by shell initialization files - check them for 'PATH=...' entries,
it might also help to re-add RVM to your dotfiles: 'rvm get stable --auto-dotfiles',
to fix temporarily in this shell session run: 'rvm use ruby-2.3.0'.
Warning, new version of rvm available '1.27.0', you are using older version '1.26.11'.
You can disable this warning with: echo rvm_autoupdate_flag=0 >> ~/.rvmrc
You can enable auto-update with: echo rvm_autoupdate_flag=2 >> ~/.rvmrc

How do I restore the “bundle” command without interfering with the Ruby 2.1.3 version I just installed?
You just need to install bundler :
rvm use ruby-2.1.6
gem install bundler
This will be installed in a gemset specific to ruby-2.1.6, so it won't interfere with anything you installed with ruby-2.3.0. You can use
bundle install
to install the required gems.
Alternatively, you could just try the example you downloaded with ruby-2.3.0 by either changing the
ruby '2.1.6'
line or deleting it from the Gemfile.
