刚刚开始学习LangChain，并将我的项目搬到LangChain上。 为了继续前进，我得到了这个 github 项目： https://github.com/Cbase-ai/asana-task-agent 我确实安装了一切。内容包含：
我试图解决许多配置的问题，但我总是遇到一些库问题。

请向我解释一下，我尝试了一切可能的方法，但似乎我错过了一些东西。 也许需求文件来自某个旧项目？很难说
我尝试了很多与库的组合，但不是每一个都确定。
运行代码并了解发生了什么
你可以尝试一下吗
pip install -U langchain-huggingface
您可能还需要
...并导入为
from langchain_huggingface import HuggingFaceEmbeddings我对此不太确定，只是看看你的日志。谢谢。
