Hi, I was trying to use uglifyjs programmatically but got this error. Anyone know how can i solve it?

Please provide a reproducible test case to illustrate your issue - there is nothing actionable with the current level of information.

I'm building a react app and using webpack to bundle it.

This line
var UglifyJS = require("uglify-js");
causes the following:

Uncaught Error: Cannot find module '../lib/utils.js'.

Sounds like a webpack issue - please file a report with them instead.

My understanding is that they are pulling out and rearranging files from uglify-js, and something breaks along the way.

What is the reason?How to deal with it

I think it's the problem of uglifyJs, the require grammar can't be static analyzed by webpack.
