Redmine

Hi,

the rake db:migrate aborts for a first installation with a message :
rake aborted!
Application has been already initialized

Note : I have also identify that there is no ./db/schema.rb file

Can you help me to solve this issue ?

Version 2.2.4

The detailed message is :
-bash-3.2$ RAILS_ENV=production rake --trace db:migrate
/appli_PP/Redmine/2.2.4/PDMS/apache/lib/ruby/1.9.1/yaml.rb:56:in `<top (required)>':
It seems your ruby installation is missing psych (for YAML output).
To eliminate this warning, please install libyaml and reinstall your ruby.

• Invoke db:migrate (first_time)
• Invoke environment (first_time)
