[xuexixiaozi101]

requirements中好像这一块有问题，AI解决不了还是报错
langchain-community>=0.3.13
langchain>=0.1.0

执行
flask db init

报错：
ImportError: cannot import name 'LanguageModelInput' from 'langchain_core.language_models'

@xuexixiaozi101 Thanks for your interests in our work. This issue seems to be the problem of langchain package updates across versions. You might turn to the following package to fix it:

langchain==0.2.15
langchain-chroma==0.1.3
langchain-community==0.2.15
langchain-core==0.2.37
langchain-huggingface==0.0.3
langchain-text-splitters==0.2.2
