Throw exception by using custom build at version 3.2.1

[woody-li]

I'm using a custom build from example at http://docs.mathjax.org/en/latest/web/webpack.html#a-custom-mathjax-build

It throw a exception after updated to version 3.2.1.

Uncaught ReferenceError: require is not defined.
At "node_modules/mathjax-full/js/components/version.js".

exports.VERSION = typeof PACKAGE_VERSION === 'undefined' ? function() {
  var load = eval('require');
  var dirname = eval('__dirname');
  var path = load('path');
  return load(path.resolve(dirname, '..', '..', 'package.json')).version;
}() : PACKAGE_VERSION;

Questions:

1. Is there any using change for it?
2. Why the code using "eval", some code quality tool treat it as a vulnerability issue.

Thanks and sorry.
There's some mistake in my config causes the exception.
