Cannot find module './transforms/babel-plugin-convert-existence-checks-to-macros'

I've recently updated ember-cli and my app to 4.10.0, and trying to build with:

ember serve

throws the following error:

Cannot find module './transforms/babel-plugin-convert-existence-checks-to-macros'

I've looked to see what module is missing. I came up with trying to install/reinstall ember-cli-babel and that didn't work either.
