Imports while testing with Jest fail

so I have React component that works well in the browser, but fails to render while testing. I am using Jest, and the component in question is a wrapper around React Sortable. While trying to launch the test, I get "_sortablejs2.default.create is not a function" error, which I have found out that is caused by imports (i.e. require('react')) returning 'undefined'. Why might that be? Other tests that I have work just fine.

Test itself:

let renderer = TestRenderer.create(
      <DragAndDropSelector
        selected={[]}
        choices={[]}
        selectedChange={ (a, b, c) => {return a} }
      />
  );
  expect(renderer.toJSON()).toMatchSnapshot();
});

My package json:

Im stumped, so any help would be appreciated:)
