Syntax error in SQLite with Rails ActiveRecord :: StatementInvalid

Start in the development of a small project to learn Ruby on Rails, I started with a small tutorial in which I do a Resources to insert data to the BD through a form, the point is that I get the following error :

ActiveRecord::StatementInvalid: SQLite3::CorruptException: malformed database schema () - near "(": syntax error: SELECT name FROM sqlite_master WHERE name <> 'sqlite_sequence' AND name = 'schema_migrations' AND type IN ('table')

Caused by:
SQLite3::CorruptException: malformed database schema () - near "(": syntax error

Tasks: TOP => db:migrate
(See full trace by running task with --trace)

Apparently this is associated with SQLite, and the conflict as I understand it refers to an SQL query that was generated automatically by the framework, the file of my table located in the db / migrate folder is:

class CreateArticles < ActiveRecord::Migration[5.1]
  def change
    create_table :articles do |t|
      t.string :title
      t.text :text

      t.timestamps
    end
  end
end 

My model for article is:

class Article < ApplicationRecord
end

My controller is:

 class ArticlesController < ApplicationController
  def new

  end

  def create
    @article = Article.new(article_params)

    @article.save
    redirect_to @article
  end

  private
  def article_params
    params.require(:article).permit(:title, :text)
  end

  def show
    @article = Article.find(params[:id])
  end
end

And my view is:

   <%= form_for :article, url: articles_path do |f| %>
  <p>
    <%= f.label :title %><br>
    <%= f.text_field :title %>
  </p>

  <p>
    <%= f.label :text %><br>
    <%= f.text_area :text %>
  </p>

  <p>
    <%= f.submit %>
  </p>
<% end %>

When executing rails db: migrate appears:

rails aborted!
ActiveRecord::StatementInvalid: SQLite3::CorruptException: malformed database schema () - near "(": syntax error: SELECT name FROM sqlite_master WHERE name <> 'sqlite_sequence' AND name = 'schema_migrations' AND type IN ('table')

The table article responds to the following SQL:

  DROP TABLE IF EXISTS articles;

CREATE TABLE articles (
    id         INTEGER  PRIMARY KEY AUTOINCREMENT
                        NOT NULL,
    title      VARCHAR,
    text       TEXT,
    created_at DATETIME NOT NULL,
    updated_at DATETIME NOT NULL
);

Some help I would appreciate it Greetings
