Error installing community node "n8n-nodes-langchain-tools" on n8n Cloud

Hello n8n community,

I am trying to build a multi-agent AI system on n8n Cloud and need to install the n8n-nodes-langchain-tools community node.

However, every time I try to install it via Settings > Community Nodes, I get the following error. I have also tried installing the older n8n-nodes-mcp-tools package and received the exact same type of error.

Here is the screenshot of the error message:

It seems to be an issue with the npm pack command failing on the n8n Cloud environment. Could you please advise on how to resolve this? Is there a specific version of the package I should be using, or is there an incompatibility with the current cloud environment?

Thank you for your help!

Hello @Mike_Liu hope all is well and welcome to the community.

Where did you install this from? Is there a maintainer associated with this community node? Do they have a github and issues page? Since this is a community node, it is most appropriate to ask whoever wrote this code. Maybe it is outdated and isn’t meant to work with current n8n version…

Hello @Mike_Liu, do you already try with the official langchain node tool? And what the difference between langchain community and the official langchain node?
