Import error about BaseSettings

Describe the bug

I installed libre-chat by using pip install libre-chat, and received the below error when tried to start.

Traceback (most recent call last):

Hello, same error for me. Did you find a solution @GuoqiangJia ?

[vemonet]

Hi @npotier and @GuoqiangJia the issue was coming from Pydantic (I use v2, and when you installed you got v1, because I did not specified a version for pydantic)

I fixed the dependencies in the latest releases by making sure pydantic installed is superior to v2

For your information, you could have fixed it by forcing to install pip install libre-chat pydantic>=2.0.0 (you don't need anymore though :) )
