[EASE THEME] Issues running `yarn dev` in Docker

Hi all,
I’m running Ghost on Docker using the official docker image. I’m trying to set it up so the CSS updates.

When I run yarn dev in the themes directory, I get this message:

root@0fc752782729:/var/lib/ghost/content/themes/ease# yarn dev
yarn run v1.22.5
warning ease@1.0.0: The engine "ghost" appears to be invalid.
warning ease@1.0.0: The engine "ghost-api" appears to be invalid.
$ gulp
