It seems your ruby installation is missing psych (for YAML output).
To eliminate this warning, please install libyaml and reinstall your ruby.

Check first if you can install libyaml:
on MacOS
or on Linux
Then gem install psych
Check out also rbenv/ruby-build issue 1251 and the GEM_HOME setting.

Resolved by adding a Gemfile.local inside redmine directory
# Gemfile.local
gem 'multi_json'
gem 'json'
then run bundle lock --add-platform x86_64-linux (get your platform from ruby -v)
followed by bundle install --without development test
I'm just starting out with Rails and am following the Ruby on Rails essential training course and get problems trying to start WEBrick. Assuming it has something to do with my installation of mysql but not sure.
I made sure that I am in the correct directory (:C\sites\simple_cms)
I ran 'bundle install' before running 'rails s'
I followed these guides to get the gem installed (second to last entry): https://github.com/brianmario/mysql2/issues/372
I have ruby 2.2.1p85, rails 4.2.1 and this rubygem: mysql2-0.3.18-x64-mingw32 installed
Would appreciate some help from y'all :)

I have been working on Ruby on Rails since 2 months go and now I want to change the database system so I installed the gem mysql2 by this command:
gem install mysql2 --platform=ruby -- '--with-mysql-lib="C:\mysql-connector\lib" --with-mysql-include="C:\mysql-connector\include" --with-mysql-dir="C:\mysql-connector"'
And It works!
but the problem is when I want to run rails server again I got this error

Do you have installed the necessary native libraries for mysql2 adaptor ?
