SPFx Gulp Build not generating manifests.js

I am struggling to find a solution for this and would greatly appreciate any help.

I am using SPFx to create a new package a build it with gulp but the manifests file is not being generated. I have followed the exact steps below:

1. yo @microsoft/sharepoint
   • Solution: SpfxTest
   • Component: Web part
   • Name: HelloWorld
   • Framework: none
2. gulp build --verbose
3. gulp serve

The temp folder with manifests.js is not created, and the path https://localhost:4321/temp/build/manifests.js returns Cannot GET /temp/build/manifests.js

Version numbers below:

C:!DevTemp\SpfxTest>node -v v22.15.0

C:!DevTemp\SpfxTest>npm -v 10.9.2

C:!DevTemp\SpfxTest>gulp -v CLI version: 3.0.0 Local version: 4.0.2

C:!DevTemp\SpfxTest>npm list --depth=0 | findstr @microsoft +-- @microsoft/[email protected] +-- @microsoft/[email protected] +-- @microsoft/[email protected] +-- @microsoft/[email protected] +-- @microsoft/[email protected] +-- @microsoft/[email protected] +-- @microsoft/[email protected] +-- @microsoft/[email protected] +-- @microsoft/[email protected] +-- @microsoft/[email protected] +-- @microsoft/[email protected]

C:!DevTemp\SpfxTest>yo --version 5.1.0

Thanks!
