[email protected] Axios Error

[gkhngyk]

Hello, While trying to update version from 0.0.55 to 0.0.56, I get the axios error. How can I fix this error. Here is the error log:

While resolving: [email protected]
npm ERR! Found: [email protected]

Thank you,

You will have to set the package axios in your package.json to 0.26.1 manually and install again, this should resolve the dependency version conflict.

I don't know why langchainjs uses such an outdated version of axios though, we are at version 1.3.4 at the moment and version ``0.26.1` is more than a year old.

By the way, I also have problems with running the Custom LLM Agent example and the axios-fetch-adapter.js seems to fail.

Any help would be greatly appreciated!

Loaded agent.

Running npm install [email protected] before npm install langchain@latest fixed it for me.

We use this version because this is the version the openai SDK uses, and we don't want people to have 2 of them in their app. If you want it updated please ask the openai folks

In my use case, everything is working well with the following package.json. Please refer to it if you want to use axios@1 right away.

  "dependencies": {
    "axios": "1.3.5",
    "langchain": "0.0.56",
    "openai": "3.2.1"
  },
  "overrides": {
    "axios": "$axios"
  }

Thank you for the explanation, that makes sense!

For anyone having the same error I had ReferenceError: Headers is not defined in axios-fetch-adapter.js: I tried to run langchainjs server side with Node.js, this is why it failed.

A quick fix for this is to install the node-fetch module and add import fetch, { Headers, Request } from "node-fetch"; at the top of axios-fetch-adapter.js.

Edit: I was using Node.js version 16.x, if you switch to 18.x you won't run into this error anymore (see https://github.com/hwchase17/langchainjs/issues/159)
