I have problem with react-x18n when I use command (npm run build) and show like this :

Creating an optimized production build...
Failed to compile.

This seems to be an issue related to uglifyjs and not react-x18n:

webpack/webpack#2972

I suggest that you try to transpile the react-x18n source code from ES6 to ES5 (either manually or with babel) and see what happens.

may u please update react-x18n to ES6 ?
