Have you run `yarn install`? It looks like the `npm-run-all` dependency is missing. See the last line here: [Getting started — Kolibri developer documentation 0.15.0.dev0+git.20210327192021 documentation](https://kolibri-dev.readthedocs.io/en/develop/getting_started.html#install-node-js-yarn-and-other-dependencies)

Yeah, I had an error while installing yarn.

**error An unexpected error occurred: “[https://codeload.github.com/learningequality/kolibri-design-system/tar.gz/4a2ae39872817e189c35db1de975c9c49b5b03fa:](https://codeload.github.com/learningequality/kolibri-design-system/tar.gz/4a2ae39872817e189c35db1de975c9c49b5b03fa:) ESOCKETTIMEDOUT”.**
