Multiple Copies of react installed #8026
Description
I am using a few react components made by various libraries like material ui and i get this message
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).
on doing npm ls react i can see only one version of react installed. I am using gulp and browserify for my build process. Any idea how i can solve this?
