我目前正在关注ruby on rails教程:http://guides.rubyonrails.org/getting_started.html.
我正在尝试将数据保存到数据库中.但是,当我运行时:rails server我收到以下错误:
Migrations are pending. To resolve this issue, run: bin/rake db:migrate RAILS_ENV=development
我查看了其他文章,当我跑步时:
bin/rake db:migrate
我得到了 rake aborted!
运行后:
rake db:abort_if_pending_migrations....
我看到:
You have 1 pending migration:
20150805200129 CreateDatabases
SQLite3::SQLException: table "databases" already exists:
它只是告诉我运行rake db:migrate再次启动.
它似乎已经存在.有没有办法取消挂起的迁移？
