根据您提供的错误信息和配置文件，问题出在 rules.yml 文件的验证上。Rasa 3.6 对规则文件的格式要求比较严格。以下是解决方案：

问题分析

错误信息显示：

1. Key 'triggers' was not defined
2. Key 'actions' was not defined

虽然您的 rules.yml 中确实定义了这些字段，但可能是格式或缩进问题导致的验证失败。

解决方案

1. 修正 rules.yml 文件格式：

version: "3.1"
rules:
  - rule: stock query rule
    condition:
      - active_loop: null
    steps:
      - intent: query_stocks
      - action: action_query_stocks

或者使用 Rasa 3.x 推荐的格式：

version: "3.1"
rules:
  - rule: stock query rule
    steps:
      - intent: query_stocks
      - action: action_query_stocks

1. 确保 domain.yml 中正确引用了自定义动作：

actions:
  - action_query_stocks

1. 验证自定义动作文件：
   确保 actions/actions.py 中有对应的动作实现：

from typing import Any, Text, Dict, List
from rasa_sdk import Action, Tracker
from rasa_sdk.executor import CollectingDispatcher


class ActionQueryStocks(Action):
    def name(self) -> Text:
        return "action_query_stocks"


    async def run(self, dispatcher: CollectingDispatcher,
                 tracker: Tracker,
                 domain: Dict[Text, Any]) -> List[Dict[Text, Any]]:
        # 实现查询逻辑
        dispatcher.utter_message(text="正在查询股票信息...")
        return []

验证流程

常见问题排查

1. 缩进问题：YAML 对缩进非常敏感，确保使用空格而非制表符
2. 版本兼容性：Rasa 3.x 的规则语法与 2.x 有所不同
3. 文件编码：确保文件保存为 UTF-8 编码

如果问题仍然存在，可以尝试：

1. 删除 __pycache__ 目录和 .rasa 缓存目录
2. 检查 Python 环境是否干净
3. 使用 rasa data validate 命令验证数据完整性

希望这些解决方案能帮助您解决问题！如果还有其他问题，请提供更多错误细节。
