I can't reproduce the error on MacOS, I cloned the fresh project and successfully run npm install. Could you explain the steps to reproduce the error? This jantimon/html-webpack-plugin#705 would be a great resource as well.

I have the same error on Linux Mint with yarn and yarn start.
npm install and npm start working successfully.
Delete the yarn.lock, than yarn also works.

It seem that yarn is not good here.

-- works
rm -rf node_modules
npm install
npm start

I have the same error when

yarn && yarn start

Probably need to update html-webpack-plugin and yarn. Try this and let me know whether it works please :) facebook/create-react-app#2352
