Cannot Remove "babel-plugin-transform-es2015-modules-commonjs"

Hey - I am also having this issue - same as #9. Except it's on the egghead series. I've also tried cloning the master branch and doing npm install then npm run validate but that also gives the error

Yeah, I still need to update things with a recent breaking change with babel. For now, you can swap out babel-preset-es2015-webpack with babel-preset-es2015 with configuration like this: FEM/03.0-es6ify...FEM/04.0-tree-shaking
