当我执行“rasa train”和“rasa shell”命令时，我没有 错误，但是当我执行“rasa x”命令时出现错误？

Answer 1

Rasa X 最新版本 (0.27.1) 有错误，所以只需按照以下步骤使 Rasa X 工作-

1. 卸载“rasa”、“rasa-sdk”和“rasa-x”（如果已安装）

2. 通过这个命令安装 Rasa X 0.26.3-

   pip install rasa-x==0.26.3 --extra-index-url https://pypi.rasa.com/simple

   • （这将自动安装兼容的 rasa 版本）
     
   • （也请确保根据您的默认 python 使用 pip / pip3）

3. 通过“rasa init”创建一个演示机器人

4. 输入“rasa x”

Answer 2

Rasa x 的最新版本来了，只需将您的 Rasa x 更新为 下面的命令： 我测试了它，它工作正常。更新一下吧

pip install rasa-x==0.27.2 --extra-index-url https://pypi.rasa.com/simple

在运行此代码之前激活虚拟环境。

Note Configuration:

Rasa - 1.9.3
Rasa SDK - 1.9.0
Rasa x - 0.27.2

不要安装 Rasa X 版本(0.27.0 & 0.27.1) 依赖不是 支持。
