ruby-on-rails - Heroku 错误：“密钥必须是 16 个字节”，但我输入的密钥是 16 个字节

Question

我第一次启动 Heroku，我收到错误“ArgumentError: key must be 16 bytes”。

我已经运行rails credentials:edit生成一个新密钥，得到了 32 个字符的密钥，运行heroku config:set RAILS_MASTER_KEY='<master key>'并被接受。但是当我运行它时我仍然得到错误。

我不确定我做错了什么。

这是完整的错误消息：

最初，master key configuration set 命令周围有引号，如下所示：'<master key>'Heroku 将其解释为 master key 的一部分。

只是为了后代，我将留下我们在评论中发现的正确格式的命令：

$ heroku config:set RAILS_MASTER_KEY=<master key>
