    Rake Migrate – Aborted!

    Posted on April 28th, 2009 by Rajeshwaran S P

    Trying out a sample application using rails, I faced a problem, getting the database tables created (migrated) using ‘rake’. Running the command

    1

    rake migrate

    threw the following error

    1
2
3
4
5

    (in /home/rajesh/Programming/rails/todolist)
rake aborted!
Don't know how to build task 'migrate'
 
(See full trace by running task with --trace)

    The search on internet forums only said that ‘rake migrate’ should do the job, but to no avail.

    The actual command to get the tables created is

    1

    rake db:migrate

    Hope this helps!

      When I use “rake db:migrate” I get this message:

      (in /Users/mladjanantic/myapp)
      !!! The bundled mysql.rb driver has been removed from Rails 2.2. Please install the mysql gem and try again: gem install mysql.
      rake aborted!
      no such file to load — mysql

      (See full trace by running task with –trace)

      But I just install the mysql driver with coommand “sudo gem install mysql”.

      What is the problem?
