Hello,

The error you're encountering is due to a conflict between the versions of the cohere-ai dependency in your project. Your project seems to have cohere-ai@6.2.2 installed, but LangChain version 0.0.122 (which seems to be installed in your project) requires cohere-ai@^5.0.2.

To resolve this issue, you can try the following steps:

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 0.0.122:

npm install cohere-ai@5.0.2

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

npm uninstall langchain

4. Install the new version of LangChain:

npm install langchain@0.0.144

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 0.0.144.

Please note that the specific version requirements for the dependencies of LangChain 0.0.144 are as mentioned in the context above.

Let me know if this helps or if you need further assistance.

Best,
Dosu

I'm still seeing this with langchain 0.0.144 and I do not have cohere-ai installed? How did you resolve this?

[nigel-daniels]

FYI I just created an empty directory and attempted to install 0.0.144 and got the above error, there is no package.lock file present. Please can you re-open this issue?

% mkdir foo

% cd foo 

% npm init
This utility will walk you through creating a package.json file.
It only covers the most common items, and tries to guess sensible defaults.

See `npm help init` for definitive documentation on these fields
and exactly what they do.

Use `npm install <pkg>` afterwards to install a package and
save it as a dependency in the package.json file.

Press ^C at any time to quit.

Is this OK? (yes)
