Rails 服务器错误 secret_key

我在 ruby​​mine 中使用 ruby​​ on rails 创建了一个应用程序。我在 Windows 电脑上制作了它，它运行正常。现在我把它转移到装有 Ubuntu 的电脑上，我用这个安装了 ubuntu教程。现在，当我在 localhost:3000 上调用 rails 服务器并在浏览器中转到该页面时出现错误。

Puma caught this error: Missing `secret_key_base` for 'development' environment, set this value in `config/secrets.yml` (RuntimeError)

我该如何轻松修复此问题？我是 Ubuntu 新手。

它清楚地说明了缺少什么以及在哪里。您需要打开“config/secrets.yml”并添加开发环境的密钥

您可以使用 irb 生成随机密钥：

irb
irb(main):001:0> require 'securerandom'
=> true
irb(main):002:0> SecureRandom.hex(64)
=>"6bb7bc01dd219ac9f074c26c4016260349f70d90f0c38ae171f2232a844bac54c0d6c6bae50eecdbcc73c828bd68076a5700449d069dc8e1ad5a43abd9386dca"

irb（主要）：003：0>

然后将那串长字符串复制到秘密文件中
