Hey @AnnaClaudiaSacute, the generated project uses yarn by default (see CONTRBUTING.md). If you want to use npm, you may have to do some additional changes. If it still doesn't work with yarn, please share a repro to take a look.

I had this problem, like a screenshot.

@AnnaClaudiaSacute I got the latest version back and it worked out. I think you fixed it in the [email protected] version. Try getting the latest version 🙂

Using yarn instead of npm solved it for me. I guess npm installs the dependencies only on the root folder of the library and not in the example directory.

Seems like the problem is we're relying on yarn to not hoist example app's dependencies to root. But npm doesn't have such an option yet. Please use yarn for now but we definitely want to support npm too.

Edit: We explicitly state npm is not supported in CONTRIBUTING.md, so please use yarn instead.
