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

我错过了什么？

【问题讨论】：

您是如何在本地设置 aws_access_key_id 和 aws_secret_access_key 参数的？您提到您将它们设置在终端中。您是否将它们设置为环境变量？
heroku config:set provider=AWS aws_access_key_id= "我的访问密钥 ID" aws_secret_access_key= "我的秘密访问密钥" aws_bucket= "存储桶名称"
你能确认它们已经设置好了吗？运行heroku config，看看变量是否设置好了。
这是我的载波初始化器的样子github.com/nerboda/myblog/blob/master/config/initializers/…
它应该列出应用环境变量的键值对。运行以下命令以添加 AWS 凭证：heroku config:set AWS_ACCESS_KEY_ID=PasteTheKeyInHereNoQuotes 和 heroku config:set AWS_SECRET_ACCESS_KEY=PasteTheSecretKeyHereAlsoNoQuotes。然后确认这些设置，运行heroku config，你应该看到两者都列出了。最后，在终端中运行heroku run console 并输入ENV['AWS_ACCESS_KEY_ID']，您应该会看到您在上一步中添加的键的值。然后，重新运行迁移。
