Compiler issue: llama-index 0.8.5.post2 requires langchain<=0.0.266,>=0.0.262, but you have langchain 0.0.352 which is incompatible.

I'm learning python, so please forgive me if my issue is stupid.

I did pip install -r requirements.txt and got this:

ERROR: pip's dependency resolver does not currently take into account all the packages that are installed. This behaviour is the source of the following dependency conflicts.
llama-index 0.8.5.post2 requires langchain<=0.0.266,>=0.0.262, but you have langchain 0.0.352 which is incompatible.

i am confused now because an older version from langchain seems to be required as the version being used. How to handle this?
