I tested it with the following versions npm -v 6.4.1 node -v v10.15.3

and it works for me.

what versions do you use?

[wouterbeek]

$ node --version
v10.16.0
$ npm --version
6.9.0
$ grunt --version
grunt-cli v1.3.2

I'm on Fedora 30.

@wouterbeek have you figured it out?

If you have a solution, I think it would be great if you could share it here :)

[wouterbeek]

@vitalis-wiens Nope, I'm not proficient in Node/NPM/Grunt, so I'm also waiting for a more qualified person to give the answer.

@wouterbeek @vitalis-wiens Hey! We can run the webserver locally using npm as well, by using the command serve develop/ which is generated through grunt package or through npm run-script release to run the server locally. I have pointed out the updates in #187 as well.
