运行 `python cli.py`时发生错误

[zhaostarr]

你好。我的环境信息：操作系统：Windows 11 开发工具：VSCode Python 版本：python-3.11.8 llama-index 版本：0.9.39

Issue: 在命令行模式下(powershell和cmd都是)运行 python cli.py时发生错误 ImportError: cannot import name 'ChatMessage' from 'llama_index.core.llms' (C:\Users\zhaos\AppData\Roaming\Python\Python311\site-packages\llama_index\core\llms__init__.py)

谢谢！ ZS

哪个地方从llama_index.core.llms import ChatMessage？

@CL-matt 看一下你的E:\ananconda\envs\RAg\Lib\site-packages\llama_index\core\我没看见有utilities这个文件夹

顺便 pip list|grep llama 我再确认一下你的版本

[CL-matt]

@wxywb
utilities文件夹是有的.

[wxywb]

@CL-matt 这样你把这些全部pip uninstall 了，然后只 pip install llama-index==0.9.39

搞定了，删除了python，重新构建了虚拟环境。主要是版本不一致。谢谢大佬
