Hi, I had a very similar issue where my babel preset options were unknown. I’m pretty new to all this, but npm install babel-preset-es2015 and npm install babel-preset-react solved my problem. I forgot to install the dependencies beforehand, and after installing them things worked out.

I solved it.💡

The issue for me was that npm install babel-loader --save-dev was installing an incorrect version of babel-loader (^5.4.0).

I edited my package.json manually, setting the version to ^6.1.0, removed the node_modules directory, and then ran npm install, which fixed the issue.
