数据库能改成mysql么？

[cybersingle]

database我改成mysql2，migrate成功了，但是assets没编译成，报错如下： D:\RailsInstaller\sites\bootstrap-rails-startup-site>rake assets:precompile --tr ace ** Invoke assets:precompile (first_time) ** Execute assets:precompile d:/RailsInstaller/Ruby1.9.3/bin/ruby.exe d:/RailsInstaller/Ruby1.9.3/bin/rake as sets:precompile:all RAILS_ENV=production RAILS_GROUPS=assets --trace ** Invoke assets:precompile:all (first_time) ** Execute assets:precompile:all ** Invoke assets:precompile:primary (first_time) ** Invoke assets:environment (first_time) ** Execute assets:environment ** Invoke environment (first_time) ** Execute environment rake aborted! database configuration does not specify adapter d:/RailsInstaller/Ruby1.9.3/lib/ruby/gems/1.9.1/gems/activerecord-3.2.14/lib/act ive_record/connection_adapters/abstract/connection_specification.rb:47:in `resol ve_hash_connection'

和数据库没关系，请将railsinstaller装在C盘，然后运行也在C盘上。
