我正在将Rails应用程序从GitHub推送到Heroku。 push命令成功执行，没有问题。但是，当我运行数据库迁移时，一次迁移成功运行，然后创建了另外两个表。创建这些表并且没有进一步的迁移时，该过程将退出。
我可以确认创建了users表。重新运行迁移会得到相同的结果

我有12个迁移文件。在我的本地计算机（Windows）上进行迁移时没有问题。
编辑：这是rake db：migrate：status的输出
$ heroku run rake db:migrate:status

Status Migration ID Migration Name

up 20190604184418 Devise create users
此外，运行rake db：schema：load而不是db：migrate会导致相同的结果，即迁移了一张表。
更新2：我使用了schema.rb和迁移，并使用它们创建了一个空白的Rails应用程序。我能够顺利推送到heroku并运行迁移。我怀疑这是某个地方或与我的seed.rb文件有关的配置问题。任何人都对为什么有任何想法，还是我需要从头开始重新制作整个项目？
更新3：放弃，从头开始创建一个新项目，使用迁移从头开始生成模型，然后在所有应用程序逻辑之间进行复制。现在一切正常。
