karma-browserify throws error when trying to load modules shimmed with browserify-shim

问题

I know there were similar questions but none of them solved my problem.

When I run karma test it throws the following error, every time it tries to load a module, that was shimmed with browserify-shim:

TypeError: 'undefined' is not an object (evaluating 'module.exports = ex')
  at /tmp/8ff1e03f7ba1f9c70ee4192510d267a2.browserify:3855:0 <- lib/underscore/underscore.js:1421:0

My karma.conf.js is the following:

module.exports = function(karma) {
    karma.set({

        frameworks: [ 'jasmine', 'browserify' ],

        files: [
            'test/spec/**/*Spec.js'
        ],

        reporters: [ 'dots' ],

        preprocessors: {
            'test/spec/**/*Spec.js': [ 'browserify' ]
        },

        browsers: [ 'PhantomJS' ],

        logLevel: 'LOG_DEBUG',

        singleRun: true,
        autoWatch: false,

        // browserify configuration
        browserify: {
            debug: true,
            transform: [ 'reactify', 'browserify-shim' ]
        }
    });
};

And here is the relevant part of my package.json file:

...
  "browser": {
    "underscore": "./lib/underscore/underscore.js",
    "jquery": "./lib/jquery/dist/jquery.js",
    "typeahead": "./lib/bootstrap3-typeahead/bootstrap3-typeahead.js",
    "bootstrap": "./lib/bootstrap/dist/js/bootstrap.js",
    "q": "./lib/q/q.js"
  },
  "browserify-shim": {
    "underscore": "_",
    "jquery": "jQuery",
    "typeahead": {
      "depends": [
        "jquery"
      ]
    }
  },
  "browserify": {
    "transform": [
      "browserify-shim"
    ]
  },
....

Any idea what can caus the problem?

回答1:

I had the same problem and have resolved it by removing the browserify-shim transform from karma configuration file, since it is already declared as a transform on package.json file.

Hope that helps.
