Fail to copy lib file for lodash!

Done.

Here's how my Gruntfile.js looks

module.exports = function(grunt) {
  var _ = require("lodash");
  _.object = _.zipObject;
  grunt.initConfig({
    "bower": {
      "dev": {
        "dest": "dist/vendor/js",
        "css_dest": "dist/vendor/css",
        "fonts_dest": "dist/fonts"
      }
    }
  });

  grunt.loadNpmTasks("grunt-bower");

  grunt.registerTask("default", ["bower"]);
};

and my package.json

{
  "name": "coc-app",
  "version": "1.0.0",
  "description": "Clash of Clans Application",
  "main": "index.js",
  "scripts": {
    "test": "echo \"Error: no test specified\" && exit 1"
  },
  "author": "",
  "license": "private",
  "dependencies": {
    "body-parser": "^1.15.0",
    "cookie-parser": "^1.4.1",
    "express": "^4.13.4",
    "jade": "^1.11.0",
    "lodash": ">=3.0.0 <4.0.0"
  },
  "devDependencies": {
    "grunt": "^1.0.1",
    "grunt-bower": "^0.21.0",
    "grunt-contrib-concat": "^1.0.1"
  }
}

I tried resetting

var _ = require("lodash");

_.object = _.zipObject;

but this did not work.

Any thoughts or suggestions?

The problem comes from the fact that Underscore and lodash don't play as well together as some might think they do. Underscore has _.object, lodash has _.zipObject.

The creators of grunt.util and grunt.utils don't share the same library preferences either, as grunt.utils._ is a reference to Underscore and grunt.util._ is a reference to lodash and so is grunt-legacy-util._, which is what your build is using (according to the stack trace).

That's a bug in grunt-bower, assuming there is _.object when they are clearly trying to support grunt.util._ too and don't have grunt.utils or Underscore as a dependency. Anyways...

Solutions

1. Include grunt.utlis

I don't have much experience on Grunt, much less grunt.utlis, but I suspect that if you grab the grunt-utils package and load it like they guide, grunt-bower should just default to that (and namely, Underscore) instead. At least looking at the source it seems so.

2. Add the _.object method directly

I'm not sure at all if this would work and in any case it seems super hacky, but much like you were trying to do,

grunt.util._.object = _.zipObject

might just do the trick without other dependencies to project. I suggest you try the first one though.

3. Fix the bug in grunt-bower *

Open an issue, maybe create a PR. It should be just a small change to one file anyways, so even forking the repo seems like a solid option if the other two won't work.

Update

There already is an open PR about this that I didn't notice before. Apparently it was made yesterday, so I bet it will get a merge in no time. Little encouragement in the comments section might not hurt though.

*Update 2

The fix is now in the master branch and available through npm in v0.21.1
