Updating dependencies

Resolving dependencies... (1.1s)

The current project's supported Python range (>=3.10) is not compatible with some of the required packages Python requirement:

- langchain-text-splitters requires Python <4.0,>=3.9, so it will not be installable for Python >=4.0

Because no versions of langchain match >0.3.26,<0.4.0

and langchain (0.3.26) depends on langchain-text-splitters (>=0.3.8,<1.0.0), langchain (>=0.3.26,<0.4.0) requires langchain-text-splitters (>=0.3.8,<1.0.0).

Because langchain-text-splitters (0.3.8) requires Python <4.0,>=3.9

and no versions of langchain-text-splitters match >0.3.8,<1.0.0, langchain-text-splitters is forbidden.

Thus, langchain is forbidden.

So, because qa-bot depends on langchain (^0.3.26), version solving failed.

* Check your dependencies Python requirement: The Python requirement can be specified via the python or markers properties

For langchain-text-splitters, a possible solution would be to set the python property to ">=3.10,<4.0"
