Problem from version5+ to Regex when using ReactNative Hermes engine

[alimek]

Problem is in that line:

ansi-styles/index.js

Line 132 in cd0b0cb

const matches = /(?<colorString>[a-f\d]{6}|[a-f\d]{3})/i.exec(hex.toString(16));

When generating hermes bytecode it is failing because Invalid regular expression: Quantifier has nothing to repeat

Some info here: facebook/hermes#89

I also think it may be related to https://github.com/facebook/jest/blob/master/packages/pretty-format/package.json and its pretty-format package.

This package targets Node.js 12. For any other platform/engine, you're on your own. We don't plan to add any workarounds for Hermes.
