Any of of 'requirejs' breaks build.

[shadowmint]

If any other module uses the requirejs api after gulp-modernizr is imported, eg:

var requirejs = require('requirejs');
requirejs.optimize({
     mainConfigFile: config.js + '/bootstrap.js',
     out: 'app.js',
     name: 'foo'
}, function(err) {
  if (err) {
    console.log(err);
  }
  console.log("Done");
});

Or, for example, using https://github.com/jlouns/gulp-requirejs-optimize ...

Then the build will fail like this:

This is because https://github.com/Modernizr/Modernizr/blob/master/lib/build.js#L154 fails to resolve anything, presumably because requirejs is initialized when the gulp-modernizr package is initially imported, and then somehow screwed up when something uses it.

I don't have any solution to this other than, 'Don't use anything that uses requirejs in your build', but I thought I'd report this here (even though technically the problem is in modernizr, not gulp-modernizr), so that frustrated folks could find it easily.

Same issue here.

@cibulka You can see the workaround we ended up using here https://github.com/hatchddigital/empty-coop/blob/master/gulp/tasks/scripts.js#L72

Basically using exec to invoke the external requirejs builder; but probably a better long term solution is just to stop using requirejs. :P

Anyhow, hope that helps.

@shadowmint Thank you! After the pain I had with the setup of my Requirejs workflow, I think I will have to use it for a while :), so for now, I settled with using Modernizr directly from command line.

Thanks for the info, I'm definitely trying the workaround later!

For now, I've resorted to use https://github.com/shinnn/modernizr-stream, so I can use Modernizr's command line along with my Gulp workflow. Maybe someone finds that useful ...
