Testing with rspec is causing an error: `Migrations are pending. To resolve this issue, run: bin/rake db:migrate RAILS_ENV=development `

when I run the rails server, localhost displays this error:

ActiveRecord::PendingMigrationError (Migrations are pending. To resolve this issue, run: bin/rake db:migrate RAILS_ENV=development):

I have run the bin/rake... and the next error says:

 $ bundle exec bin/rake db:migrate RAILS_ENV=development

StandardError: An error has occurred, this and all later migrations canceled:

  SQLite3::SQLException: table "votes" already exists: CREATE TABLE "votes" 
  ("id" INTEGER PRIMARY KEY AUTOINCREMENT NOT NULL, "value" varchar(255), 
 "user_id" integer, "post_id" integer, "created_at" datetime, "updated_at"  
 datetime) 

_create_votes.rb

class CreateVotes < ActiveRecord::Migration
  def change
create_table :votes do |t|
  t.string :value
  t.references :user, index: true
  t.references :post, index: true

  t.timestamps
    end
  end
end

Basically, it tells me I have migrations pending, but when I attempt to migrate it says the table already exists.
