Cannot read property '.css' of undefined

[JakobJingleheimer]

I have require('ignore-styles') in my karma config (an entry file), and ignore-styles is throwing the following error:

Uncaught TypeError: Cannot read property '.css' of undefined
  at webpack:///…/node_modules/ignore-styles/lib/ignore-styles.js:45:0

ignore-styles.js#L45:

    oldHandlers[ext] = require.extensions[ext];

I also tried adding --require ignore-styles to the mocha command, but it did nothing.

Also, it would be great if the readme said where to put the code.

it seems that, the node new version has removed require.extensions

Hi! Sorry for the delay on this! I'm planning to clean up pull requests in my open source projects this week, after losing track during a job transition. 😅 Thanks for your patience!
