Pnpm 10.5.2 support

[gepbird]

Bug Description

When trying to build n8n with pnpm 10.5.2, I get the following error:

ERROR  The following patches were not applied: bull@4.12.1, pkce-challenge@3.0.0, pyodide@0.23.4, @types/express-serve-static-core@4.17.43, @types/ws@8.5.4, @types/uuencode@0.0.3, vue-tsc@2.1.10
Either remove them from "patchedDependencies" or update them to match packages in your dependencies.

In nixpkgs we try to use the latest version of packages, therefore currently pnpm 10.5.2. I understand that you tested it with pnpm 10.2.1, this is more of a "feature request" than a bug report.

To Reproduce

1. clone the repo
2. have pnpm 10.5.2 installed
3. pnpm i
4. observe the error

Expected behavior

It installs dependencies without errors

Operating System

NixOS

n8n Version

1.81.4

Node.js Version

22.14.0

Database

SQLite (default)

Execution mode

main (default)

Hey @gepbird,

We have created an internal ticket to look into this which we will be tracking as "GHC-1042"

Unable to reproduce this on the latest master, even on a fresh clone.

That said, while we understand the need to use the latest packages, we do not recommend latest versions of dev-tooling for end users.
Would it be possible to install n8n from npm, instead of compiling it from source?

[gepbird]

Thanks for your quick response!

Interesting that you can't reproduce it, I'll also investigate it soon. We'd like to build n8n from source, currently 1.75.2 builds fine with pnpm 9.15.5, we've been using the latest pnpm 9.x.x without issues so far.

Also other pnpm commands fail in n8n's directory, and weirdly there's another error when leaving and entering the directory:

Removing the pnpm pin seems to do the job.

[netroy]

can you try installing pnpm via corepack?

This was a pnpm bug which is fixed in https://github.com/pnpm/pnpm/releases/tag/v10.6.1:

• Don't ignore pnpm.patchedDependencies from package.json pnpm 10.6.0 breaks patchedDependencies pnpm/pnpm#9226.

Sorry for the noise about it here
