The babel-plugin-transform-dynamic-import package is not specified in babel-preset-react-app's package.json. It appears that it was switched out with babel-plugin-dynamic-import-node in create.js here:
https://github.com/facebook/create-react-app/commit/52fcb23b0d3b80a3d79e3863a27372e83dded1e7
This commit updates it in dependencies.js too.
I ran into this while working on my SSR fork. The build script was failing before this commit, but is works correctly after the switch.
