Electron-React-Devtools does not minify with React's NPM Build command

When the` npm run build` command is run to build the production React app (to later be used by ElectronJS, of course), the following error message outputs:

```
Creating an optimized production build...
Failed to compile.

Failed to minify the code from this file:

        ./node_modules/electron-react-devtools/api.js:4
```
