无法将迁移推送到 Heroku

Question

我在 Heroku 上有一个 rails 应用程序。我可以连接到它，推送构建，然后看到它 运行ning.

问题：我无法在 db>migrate 文件夹中推送包含迁移的构建。任何这样做的尝试都会给我一个

的错误

remote: Run `bin/rails db:migrate` to update your database then try again. remote: You have 3 pending migrations: remote: 20210326003113 CreateUsers remote: 20210326004504 CreateAlerts remote: 20210326004819 CreateContacts remote: Waiting for release.... failed. To https://git.heroku.com/*appname* 3dca123..cc0f499 master -> master

我 运行 我在本地迁移，提交，在本地测试它们（它们工作），然后以与上面相同的响应推送到 heroku。

我可以运行heroku run bin/rails db:migrate 这给了我一堆警告的回应。

检查日志，它告诉我无法创建用户，因为我的用户 table 不存在。用户 table 不存在，因为没有迁移。使用 heroku run rake db:migrate 没有任何作用，因为 Heroku 上的构建不包含任何迁移。我无法推送带有迁移的构建，因为它告诉我有待处理的迁移。

任何有关此第 22 条军规的帮助都将非常有用。如果需要，可以随时 post 日志。

解决方案在我的 Procfile 中。 我需要使用 bundle exec rails s。 在我使用 release: bin/rails db:migrate
