Adding to @Chetan's answer on this thread:

I ran into this issue today while following through Dr. Axel Rauschmayer's book here. Per book, babel-loader should download babel-core as well. However this is not the case when I tried it out. I think this relates to @theJian's answer.

Since the original package.json already lists babel-loader as dependency, running the following command resolved the error.

npm install babel-core --save-dev
