Whenever I use babel-plugin-react-css-modules, I get errors from babel-loader

Whenever I use babel-plugin-react-css-modules, I get errors from babel-loader, but without using the plugin in my babel config, everything seems to work fine. I was using react-css-modules before trying to migrate to this one. Everything also works fine with react-css-modules, but now it braeks.

This is the error from npm
```
ERROR in ./js/components/index.js
Module build failed (from ../node_modules/babel-loader/lib/index.js):

Comienza reproduciendo el fallo de js/components/index.js con babel-plugin-react-css-modules habilitado y, después, inspecciona el stack trace de babel-loader a través de regjsparser/parser.js. Se considera completado cuando la misma compilación termina sin el error classEscape indicado; el issue no proporciona configuración, versiones ni una prueba que ejecutar.
