Thanks for your report. It would be great if you reduce your issue to a small reproducible example. Best put this example into a github repository together with instructions how to get to the problem.

--- detail no need anymore because joshuan found the easiest way to reproduce the issue ---

@montogeek for reproduce issue you not need project. Just go this code:
cd /tmp && npm i webpack webpack-cli && ./node_modules/.bin/webpack
it is only important - node.js version: 12.0.0

我也发现了这个问题，webpack-dev-server在nodev12的环境下不能要运行。而vue-cli和Create-react-app都是用到了这个包。目前我的解决办法是把node环境降级到v11.5

I think problem in webpack-dev-server, please create minimum reproducible test repo

[alexhochreiter]

I am getting the same result, taking the reproducing steps that OP provided. Any create-react-app that is based on webpack is now broken with node 12.0.0.
Edit: This appears to have been fixed with node 12.1.0

Currently, this problem does not occur in Node12.1.0 so I'll close.

cd /tmp && npm i webpack webpack-cli && ./node_modules/.bin/webpack

I confirm, updating to node 12.1.0 fix the issue.
