Cannot install latest langchain js package

[drobnikj]

I cannot install the latest version because of the dependency tree.

npm install langchain

ends up with the error

Hello,

The error you're encountering seems to be due to a mismatch in the version of cohere-ai that langchain is dependent on. The error message suggests that langchain is looking for cohere-ai version >=6.0.0, but version 5.1.0 is currently installed in your project.

Here's a potential solution based on similar issues that were resolved in the langchainjs repository:

1. Uninstall the current version of cohere-ai in your project:

npm uninstall cohere-ai

2. Install the version of cohere-ai required by langchain:

npm install [email protected]

3. Uninstall the current version of langchain in your project:

npm uninstall langchain

4. Install the new version of langchain:

npm install langchain

If the issue persists, it might be due to other conflicting dependencies in your project. In this case, you might need to update your dependencies to the versions required by langchain.

Please note that the actual package names for langchain and cohere-ai might be different, so make sure to use the correct names when adding them to your dependencies.

If you're still encountering issues after trying these steps, please provide more information about your project setup, such as your Node.js version, npm version, and the contents of your package.json file.

I hope this helps! Let me know if you have any other questions.

This commit breaks chroma-core/chroma@9e05cb3

Can you check @tazarov it here?

[drobnikj]

I found the fix is on the way chroma-core/chroma#1156 👍

[tazarov]

@drobnikj, sorry, I was working late last night, and I did intend to include Cohere 6.x, but for some reason, that slipped. Apologies for the inconvenience :). We're working on a set of tests to validate ecosystem impacts, so hopefully, this is the "last" of these problems :)

Please, with each update the same thing happens, what version of Langchain should we put now?

[jacoblee93]

I think we should also make all our peer deps either * or >= going forwards - I was hoping doing this for Chroma would prevent issues like this.

@drobnikj for now you can also run npm install langchain --with-legacy-peer-deps or just use yarn/pnpm who have saner defaults for this.

[jacoblee93]

For now @tazarov please release another Chroma version ASAP!

[tazarov]

@jacoblee93, new version's up, mind giving it a go? https://www.npmjs.com/package/chromadb

Seems good, thank you!

Hopefully this will be the last time this pops up.
