Building applications with LLMs through composability.

Legacy chains, langchain-community re-exports, indexing API, deprecated functionality, and more.

Version history 1

1.0.8 2026-07-14 b807d69740

Upstream's version as each commit to the port's Makefile set it, or as this site first saw it in the system's packages; the tree's own revisions are not versions here.

Install

Binary package:

mport install ${PYTHON_PKGNAMEPREFIX}langchain-classic

From mports:

cd /usr/mports/ai/py-langchain-classic && make install clean

To depend on this port in another port's Makefile:

RUN_DEPENDS=	${PYTHON_PKGNAMEPREFIX}langchain-classic>0:ai/py-langchain-classic

Dependency graph

Ports that need it on the left, what it needs to run on the right; at most 8 of each. "Dependencies" below lists them all.
