Chapter 10: Could not find table 'accounts'

Given I put sqlite3.dll and sqlite3.exe into bin directory of Ruby installation
And I’ve installed sqlite3 gem using

gem install sqlite3

And I wrote code in the beginning of chapter 10 before first run of Cucumber
But I don’t have bank.db file in /db directory
When I run cucumber
Then I get error ”””

  Given my account has been credited with $100            # features/step_definitions/account_steps.rb:1
    Could not find table 'accounts' (ActiveRecord::StatementInvalid)
    ./features/support/world_extensions.rb:14:in `new'
    ./features/support/world_extensions.rb:14:in `my_account'
    ./features/step_definitions/account_steps.rb:2:in `/^my account has been credited with (\$(?:\d+))$/'
    features\cash_withdrawal.feature:3:in `Given my account has been credited with $100'
  

””“

How can I solve it?

I’ve just runned

path/to/project/db/bank.db

and bank.db was created.
But when I run cucumber migration doesn’t occur and table isn’t created
