Project build fails with your module

[annaStarshotsoftware]

Hi,
I have fixed the previous issue, it was failing with ES6 syntax, I put it to 5 and works ok.
The problem now is that I'm trying to build my app and I have an error.

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

Failed to minify the code from this file: 

        ./node_modules/react-voice-components/lib/VoicePlayer.js:3 

I wait for your answer, please answer.
