Build fails after upgrading to v2

[fabioDMFerreira]

Describe the bug

After upgrading react trello from version 1 to version 2 I started to get the next error on building my application (bootstrapped by create-react-app).

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

Failed to minify the code from this file:

        ./node_modules/react-trello/dist/styles/Base.js:12

Comment uglify plugin in webpack configuration script fixes the problem, but I want to keep the bundle as small as possible. It may be related with modern javascript features that were introduced in this new react-trello version as create-react-app documentation suggests.
https://facebook.github.io/create-react-app/docs/troubleshooting#npm-run-build-fails-to-minify

Also tried other solutions:
ccxt/ccxt#299
mishoo/UglifyJS#2011

The problem seems solved in the new create-react-app version. It uses webpack 4 and uglify was deprecated.

To Reproduce
Steps to reproduce the behavior:

1. Download repository from next origin:
   https://github.com/fabioDMFerreira/react-trello-webpack-3
2. Run npm run build

Expected behavior
Build bundle without problems.
