尝试在 config/boot.rb 的开头添加它

require 'yaml'
YAML::ENGINE.yamler= 'syck'

仅作记录，YAML 不接受制表符作为缩进，它们必须是空格。将制表符更改为空格为我解决了^^

堆栈转储提到了 database_configuration，所以我将从您的 database.yml 文件开始。

“无法解析 Yaml” 转到您的项目并查看项目名称附近有一个！签名。打开它并查看发生在哪个文件冲突。右键单击该文件，选择替换为然后从存储库中更新。对您更改代码的所有文件执行此操作。然后运行服务器它将工作。

我在我的一个 YAML 文件中使用未引用的 * 发出了这个问题。

fr:
  simple_form:
    yes: Oui
    no:  Non

    required:
      text: required
      mark: "*"

希望它会有所帮助。:)
