我在数据库设置中重置Heroku上的数据库并运行heroku run rake db:migrate.尽管它为每个本地数据库创建了具有正确列的所有数据表,但它不会迁移任何现有本地数据.Heroku数据库只是空的.在过去我运行上面的代码并且工作正常,但这次卡住了如下所示:
mac-a:skiny ran$ heroku run bundle exec rake db:migrate
Running bundle exec rake db:migrate on ? blooming-citadel-66205... up, run.3076 (Hobby)
The PGconn, PGresult, and PGError constants are deprecated, and will be
removed as of version 1.0.
You should use PG::Connection, PG::Result, and PG::Error instead, respectively.

ActiveRecord::SchemaMigration Load (1.2ms) SELECT "schema_migrations".* FROM "schema_migrations"
作为一个注释,我在运行时退出mac终端heroku run rake db:reset,也许有一些内部错误......
