Possible fix: #6395

[leonardoampuero]

I had to add this to my package.json to make it work
"devDependencies": { "fork-ts-checker-webpack-plugin": "0.5.2", "typescript": "3.3.3" },

We decided to revert #5903 to fix react-dev-utils for downstream consumers. This will give us a bit of time to figure out the best solution for how to consume the fork-ts-checker-webpack-plugin dependency.

2.1.5 is now available
