Question

我正在尝试制作一个模拟restful json api

使用此链接：

https://scotch.io/tutorials/build-a-restful-json-api-with-rails-5-part-one

但是当我尝试运行以下命令时

捆绑exec rspec

的ActiveRecord :: PendingMigrationError

生成错误

我在堆栈溢出中尝试了许多解决方案但到目前为止没有效果

C：\ ruby \ imran-api＆gt; bundle exec rspec C：/Ruby23-x64/lib/ruby/gems/2.3.0/gems/activerecord-5.0.2/lib/active_record/migration.rb：573：在`check_pending！':( ActiveRecord :: PendingMigrationError）

迁移正在等待处理。要解决此问题，请运行：

    bin/rails db:migrate RAILS_ENV=test
