I have tried several examples of SPFx extensions. All samples have the same result with respect to the tests (
swallow serve) after following the instructions on the examples page.
Most of them just need
npm install and adjustments in the serve.json file. However, every time I test it, the extension is not loaded. I will not have any error or anything, but it does not load / do not run.
Even though I am the helloworld tutorial of the series of official tutorials, the extension does not show up (with the exception of the very first step alert).
I have also tried on different machines and on different networks, but I have never managed to get samples to do anything.
does anyone have an idea?
Version Node.js: 10.15.3
npm version: 6.4.1
gulp version: 2.1.0
Edit: If you try with NodeJS 8.16 LTS, the same problem arises.
