Project does not compile after creation

[garritfra]

After creating a project via gatsby new blog https://github.com/dschau/gatsby-blog-starter-kit and starting it with npm start, I get the following output:

► npm start

> gatsby-blog-starter-kit@1.2.0 start /Users/frankeg/dev/blog
> npm run develop

> gatsby-blog-starter-kit@1.2.0 develop /Users/frankeg/dev/blog
> gatsby develop

The above error occurred in the <StoreStateProvider> component:
    in StoreStateProvider
    in App

React will try to recreate this component tree from scratch using the error boundary you provided, App.
Warning: App: Error boundaries should implement getDerivedStateFromError(). In that method, return a state update to display an error message or fallback UI.

I suppose this has to do with a new version of react, but cant exactly point out what it is. could you take a look at this?

This isn’t an issue with the starter.

Did you use yarn to install dependencies?

[DSchau]

What seems to be happening is later versions than are pinned in yarn.lock are being installed.

I used npm in this case. That's probably it. Closing this issue, thanks!
