Rails在运行rake db时出现的错误:在heroku上迁移db:seed

Question

当我为rails publify博客运行rake :migrate:时，我得到了这个错误

我已经根据publify的github页面- https://github.com/publify/publify上的说明在AWS终端中设置了这些参数

我遗漏了什么？

Answer 1

运行以下命令来添加AWS凭据：heroku config:set AWS_ACCESS_KEY_ID=PasteTheKeyInHereNoQuotes和heroku config:set AWS_SECRET_ACCESS_KEY=PasteTheSecretKeyHereAlsoNoQuotes。然后，要确认这些设置，运行heroku config，您应该看到这两个列表。最后，在终端中运行heroku run console并键入ENV['AWS_ACCESS_KEY_ID']，您将看到在前一步中添加的键的值。然后，重新运行你的迁徙。
