React 16 removed the ability to access React's internals through react/lib/.. . Doing so has always been frowned upon, but it became a hard error in the latest version.

If your code is relying on importing from that directory, you'll need to fix it. If one of your dependencies is relying on it, then they'll need to fix it. Based on David Tryon's comment, it sounds like you need to update Enzyme to v3 in this case.
