I am trying to update n8n self-hosted via npm. Running npm update -g n8n gives me this;

  run `npm fund` for details

After the above, still stuck on 1.105.3. I tried all kinds of things like running the install command, uninstalling and reinstalling, nothing appears to work.

What is the error message (if any)?

none

Running ‘n8n –version’ shows 1.105.3 regardless of my update attempts

Managed to get it updated by completely uninstalling and removing all traces of n8n from the system. Reinstalled it and confirmed that it is now on latest.

New issue now, getting the below when navigating to :5678;

Cannot GET /

The culprit was this log;

Error: Cannot find module ‘ajv/dist/core’

Complete reinstall again and managed to get it back up and running again.

There HAS to be a better way to handle updates…

I had the same issue with updating our self-hosted n8n instance.

Probably not the ideal fix but I found running npm config set legacy-peer-deps true prior to the upgrade resolved the peer dependency errors

Guys, I was having the same problem.
I think it was stemming from the npm running the wrong/old version existing in my system for some reason.
I asked it to one of the LLMs, and it said:

1. Use npx

The most straightforward method is to prefix your command with npx. This tool automatically finds and runs the command from your project’s local node_modules directory.

Bash

npx n8n start

This is the recommended way to run locally installed packages without having to worry about your system’s PATH.

which seems to work for me!
