Answer 1

Have you googled your problem?!

Look at it http://www.redmine.org/boards/2/topics/36728

Author of the redmine issue was managed to fix a problem by adding gem 'psych' to Gemfile (and of course running bundle install). Try it - maybe it helps you

Answer 2

you should update rubygem and install bundle 1.17.3

gem update --system 
or
gem update --system 2.7.6 

gem install bundle -v 1.17.3
