The newest version causes a Error: Cannot find module '@babel/runtime/helpers/interopRequireDefault' error, which can be fixed by adding an @babel/runtime to the dependencies.

I'm not going to try making a PR as I'm not familiar with babel and am not positive this is the correct solution, but as far as I can tell, from the docs here https://babeljs.io/docs/en/babel-plugin-transform-runtime, it is.
