Description

When importing something from "@langchain/langgraph" the code does not run. The following error is printed

SyntaxError: The requested module '@langchain/langgraph-checkpoint' does not provide an export named 'InMemoryStore'
    at ModuleJob._instantiate (node:internal/modules/esm/module_job:171:21)
    at async ModuleJob.run (node:internal/modules/esm/module_job:254:5)
    at async onImport.tracePromise.__proto__ (node:internal/modules/esm/loader:482:26)
    at async asyncRunEntryPointWithESMLoader (node:internal/modules/run_main:117:5)

This happens since versions

  • "@langchain/core": "0.3.8"
  • "@langchain/langgraph": "0.2.12"

Code sample

import { END } from "@langchain/langgraph";

function main() {
    console.log(END);
}

main()

NodeJS v22.6.0

Temporary solution

Backport to 0.2.11

Can confirm I have the same bug.

Can you reinstall from scratch? We renamed this but seems that we didn't narrow the dep properly. Will push a fix in the next version.

Amazing, thank you a lot. I couldn't provide you feedback yesterday given the fact I was not on the computer. However, it seems like you have already released a new version.

So thanks! Have an amazing rest of the week & weekend.
