Cannot use db Migrate, rake aborted error

I am working a new project in Codeanywhere (I am new on Ruby), but when I try to use "rake db : migrate" I have this error:

rake aborted!                                                                                                                                                                                                                                        
Don't know how to build task ':' (see --tasks)                                                                                                                                                                                                       
/home/cabox/.rvm/gems/ruby-2.1.2/gems/rake-12.0.0/exe/rake:27:in `<top (required)>'                                                     
(See full trace by running task with --trace)

Before this I use bundle update and after and nothing, and when I put "rake-T", db Migartion is on the tasks, when I try with --trace, pass the same.

I try before with rake db:migrate and the same happened `rake aborted!

Does anyone know how to solve this problem?

In the migration file I have:

class CreatePosts < ActiveRecord::Migration
  def change
    create_table :posts do |t|
      t.string :title
      t.strind : 
      t.text :body 
      t.timestamps
    end
  end
end

I am pretty sure what is happening is you are inserting a space in there when you type it out. It needs to be

rake db:migrate

not

rake db : migrate

That error message is pretty common when there is a spelling error or some other kind of typing error when running the command.

Your migration has a typo as well, should be this

class CreatePosts < ActiveRecord::Migration
  def change
    create_table :posts do |t|
      t.string :title
      t.text :body 
      t.timestamps
    end
  end
end

Rake is a software task management tool, similar to Make, etc. in other systems

The generic syntax is 

rake namesapce:task

In your case it is

rake db:migrate

Try doing rake db:reset if you want to rebuild your db again. It does 4 things for you

rake db:drop
rake db:create
rake db:migrate
rake db:seed
