deno Uncaught Error: Not implemented: Pipe.prototype.listen

Version: Deno 2.0.0-rc.5 (release candidate, release, x86_64-pc-windows-msvc)

When I run deno run -A .\node_modules\nx\bin\nx.js serve projectName

I get the following error

 NX   Failed to start plugin worker.

Is that a compatibility issue, a nx issue or a windows issue?

Sep 25 '24 15:09 sschneider-ihre-pvs

It's a compatibility issue. This API is not yet supported in Deno.

Sep 25 '24 15:09 bartlomieju

ok. At least I got that question out of the way :D

Sep 25 '24 15:09 sschneider-ihre-pvs

Is there a workaround or something?

Sep 25 '24 15:09 sschneider-ihre-pvs

I'm not really familiar with internals of nx, but I'm afraid there might not be a workaround at the moment.

Sep 25 '24 15:09 bartlomieju

Steps to reproduce:

Create a new simple NX workspace

deno run -A npm:create-nx-workspace@latest deno-nx --preset node-standalone --ci skip --docker false --framework none --interactive false

Navigate to the created folder

cd deno-nx

Run the program through NX

deno run start

Output will be the same as in the post above.

Error originates from the server.listen(socketPath); line here: https://github.com/nrwl/nx/blob/master/packages/nx/src/project-graph/plugins/isolation/plugin-worker.ts#L136

A "support NX" issue was previously closed, but it seems like it doesn't work correctly yet: https://github.com/denoland/deno/issues/22966

Just to update it is still around in 2.0.4

Using Deno v2.1.1 and nx v20.0.3 I am getting a different error, but the cause remains the same.

Task start nx serve

 NX   Nx Daemon was not able to compute the project graph.

Nx Daemon is going to be disabled until you run "nx reset".

this'll also make npm:node-notifier not work :)
