Invariant Violation: addComponentAsRefTo(...)

[prashaantt]

New to React and MUI here. I know this is a common issue and usually goes away by removing conflicting React versions, but I've verified that there's only one version of React in my project (per npm ls | grep react).

My code (adapted from the live example) looks like this:

...
render() {

  return (
    <div>
      <Paper .../>
      <Popover .../>
    </div>
  );
}
...

Paper works on its own, but not when combined with Popover. I'm using Webpack to build React 0.14 and MUI 0.13.

Never mind, deleting all of my node_modules and npm installing again fixed this for me.
