dlopen Symbol not found error on macOS 10.15.7 and Netlify

[JavascriptMick]

Describe the bug
Trying to run the following code...

import { FaissStore } from "langchain/vectorstores/faiss";
import { OpenAIEmbeddings } from "langchain/embeddings/openai";
const vectorStore = await FaissStore.loadFromPython('./data/saved_index/', new OpenAIEmbeddings());
const results = await vectorStore.similaritySearch(query, 5);

Fails with the following Error on macOS 10.15.7

Uncaught (in promise) TRPCClientError: Could not import faiss-node. Please install faiss-node as a dependency with, e.g. `npm install -S faiss-node` and make sure you have `libomp` installed in your path.

Error: libgomp.so.1: cannot open shared object file: No such file or directory

Environment:

• Operating system: macOS 10.15.7
• Nodejs Version: v18.12.1
• Package Version: [e.g. v0.2.0]

To Reproduce
Steps to reproduce the behavior:

1. npm install faiss-node and "langchain": "^0.0.84"
2. run the above code

Expected behavior
index is rebuilt from python files and returns data

Screenshots

Additional context
I was able to get my local environment running by

1. git checkout faiss-node & npm install
2. Upgrade my CMake
3. npm run build
4. npm link
5. then back in my project... npm link faiss-node... effectively swapping out the locally built module for my project and it's dependencies

So I guess it's just an issue with compiling the library for older versions of macOS?

Here are my package.json dependencies

  "dependencies": {
    "@pinia/nuxt": "^0.4.6",
    "@trpc/client": "^10.9.0",
    "@trpc/server": "^10.9.0",
    "daisyui": "^2.51.5",
    "faiss-node": "^0.2.0",
    "generate-password-ts": "^1.6.3",
    "langchain": "^0.0.84",
    "openai": "^3.2.1",
    "pickleparser": "^0.1.0",
    "pinia": "^2.0.30",

    "superjson": "^1.12.2",
    "trpc-nuxt": "^0.8.0",
    "zod": "^3.20.2"
  },

and faiss-node in my package-lock.json...

    "node_modules/faiss-node": {
      "version": "0.2.0",
      "resolved": "https://registry.npmjs.org/faiss-node/-/faiss-node-0.2.0.tgz",

@JavascriptMick Thanks for reporting the issue.

1. For error on macOS 10.15.7

So I guess it's just an issue with compiling the library for older versions of macOS?

I think this is the reason. The pre-build binary was compiled on macOS 12.6, some symbols on new version may not exist on the old version. Compiling it yourself may be a good option for now. I will add documentation later on how to compile.

2. For error on Netlify

Please try to install the missing package to see if it helps
sudo apt-get install libgomp1 or yum install libgomp

I will further study whether there is a better solution on this issue.
