Error: Can't walk dependency graph: Cannot find module 'env!env/file' from './node_modules/requirejs/bin/r.js'

Type of bug

• Modernizr error

Describe the bug
When attempting to use the Modernizr runtime with through a compilation tool like Gulp, I get the following error from Node:
Error: Can't walk dependency graph: Cannot find module 'env!env/file' from './node_modules/requirejs/bin/r.js'

How to Reproduce
Install via NPM:

npm install modernizr --save

Initialise Modernizr

const modernizr = require('modernizr');

// Options passed in are those described in https://github.com/Modernizr/Modernizr/blob/master/lib/config-all.json
modernizr.build({ ... });

Expected behavior
This implementation of Modernizr should be parseable without errors during compilation.

Additional context
Modernizr version: 3.11.8

I appreciate that this could be a bug with Requirejs, but I'm not finding any issues similar to mine in either repo at the moment. Based on the fact that requirejs is a dependency of Modernizr, it made sense to report the issue here.

Additionally, I have also confirmed that the issue is not caused by the build tools I am using.

Edit - more context
Interestingly, when testing the example above and compiling with Webpack, we still get errors - but slightly different:

These dependencies were not found:

* generate in /node_modules/modernizr/lib/build.js
* lib/generate-banner in /node_modules/modernizr/lib/build.js
* package in /node_modules/modernizr/lib/build.js

To install them, you can run: npm install --save generate lib/generate-banner package

It feels as if this could be the root of the problem, where Gulp and Webpack are reporting different symptoms of the same problem.
