有人可以帮我解决我的yaml文件错误吗？我收到以下错误。我甚至尝试使用yaml格式化程序，yaml格式化程序说这是一个有效的yaml文件

！/ bin / sh -eo pipefail无法解析YAML expect''，但在'string'中找到''，第39行，第1列：工作流程：警告：此配置是自动生成的，以显示上面的消息。不要重新运行这份工作。重新运行将无效。 false退出代码1

Answer 1

您的文件以缩进为两个空格的键值对开始，因此您有一个根级别节点作为映射。只要所有其他根级别也缩进两个空格，那就没问题了。

workflows没有缩进，这就是解析器期望新文档的原因。

我通过用2个空格缩进workflows来解决上述问题
