Uncaught Invariant Violation: addComponentAsRefTo(...)

[blvrd]

This issue may not belong here, but it's worth a try. I'm attempting to use react-map-gl inside a Rails project. I'm using this repo as a starting point.

After running npm install react-map-gl --save and including the code snippet from the readme, I get this error:

Uncaught Invariant Violation: addComponentAsRefTo(...): Only a ReactOwner can have refs. You might be adding a ref to a component that was not created inside a component's `render` method, or you have multiple copies of React loaded (details: https://fb.me/react-refs-must-have-owner).

After a ton of Googling, it seems that the problem is that two copies of React are being included on the page. However, I can't seem to find the duplicate dependency inside of react-map-gl. Any help would be much appreciated, and sorry if this is not a relevant issue for this project.

@garrettqmartin8 react-map-gl's package.json lists react as a (peer dependency)[https://github.com/uber/react-map-gl/blob/master/package.json#L68] for this very reason (i.e. react-map-gl does not install its own version of react but uses a compatible version installed by the app), so I would first look elsewhere for the problem.

I'll close this out for now until there is more evidence this is react-map-gl related.
