linux - Ruby-on-rails - rake db:migrate - error -

-

my question error when try run command: rake db:migrate on linux vm set @ nitrous.io. error "rake aborted!". here snapshot: ~/workspace/myblog$ rake db:migrate rake aborted! no rakefile found (looking for: rakefile, rakefile, rakefile.rb, rakefile.rb)

i've searched on stack overflow , found several similar questions , answers. before try of specific responses wanted ask question bit differently. reason answers seem remarkably varied , specific others environments.

here thoughts:

  1. is problem suspect "path" settings aren't finding rake file needed?

  2. if so, can find ways fix in linux?

  3. to vm set followed great instructions at: http://railsapps.github.io/rubyonrails-nitrous-io.html in doing created directory "myblog" app in workspace directory can see above. and/or standard practice?

all of driven work in coursera mooc called "web application architectures". i'm new rails , ruby using nitrous.io.
