你们现在重新装 会报错，以前装的不会 ，应该是 python环境变化了

++1 兄台最后解决了咩

[haojieZzz]

主要两步：

1. 升级/server/requirements.txt 中 两个库的版本号为：

langchain==0.0.154
llama_index==0.6.15

2. /server/doc_util.py中 line5 改为如下：

from llama_index import SimpleDirectoryReader, QuestionAnswerPrompt, LLMPredictor, GPTVectorStoreIndex as GPTSimpleVectorIndex
