Facing same issue, any update on this?

I encountered a challenge recently, but thankfully found a solution by switching to FAISS instead of hnswib. To resolve the issue, I used the following command to install FAISS:

npm install -S faiss-node

Then, I imported the FaissStore from the langchain/vectorstores/faiss module:

import { FaissStore } from "langchain/vectorstores/faiss";

This issue is caused by the removal of distutils, which is required by node-gyp, from Python 3.12. By running the following command, distutils will be installed and the problem will be resolved.

$ pip install setuptools

I get this post-install script error with python 3.11 and node 20, how to fixed it? @yoshoku

If you run on MacOS, try to install python-setuptools first:

brew install python-setuptools

Then you can go with (for yarn users) 🙌:

yarn add hnswlib-node

or with npm

npm install hnswlib-node
