Could not find any modules. Did you remember to set 'preprocessors' in your Karma config?

Followed the configuration in the read me but I am getting the following error:

Error: Could not find any modules. Did you remember to set 'preprocessors' in your Karma config?
  at /Development/codecentric/angular2-hamis-seed/node_modules/karma-commonjs/client/commonjs_bridge.js:5

I also tried setting the commonjs Preprocessor option but did not help.

Part of the config:

Any idea's?

Did you set the files option?

[hrietman]

Yes I did,

files: [
            // paths loaded by Karma
            {pattern: 'node_modules/es6-shim/es6-shim.min.js', included: true, watched: true},
            {pattern: 'node_modules/systemjs/dist/system-polyfills.js', included: true, watched: true},

            {pattern: 'node_modules/systemjs/dist/system.src.js', included: true, watched: true},

            // paths loaded via module imports
            {pattern: 'src/**/*.js', included: false, watched: true},

            // paths loaded via Angular's component compiler
            // (these paths need to be rewritten, see proxies section)
            {pattern: 'src/**/*.html', included: false, watched: true},
            {pattern: 'src/**/*.css', included: false, watched: true},

            // paths to support debugging with source maps in dev tools
            {pattern: 'src/**/*.ts', included: false, watched: false},
            {pattern: 'src/**/*.js.map', included: false, watched: false},

            {pattern: 'test/karma/specs/**/*.js', included: false, watched: false},

        ],

Reading up on the other issues, it seems it has to do with dependencies on modules in the node_modules folder.

Any updates @hrietman ?

@brandonros This is almost a year ago; I since moved on with Angular-cli to setup projects; however here is my current karma configuration, maybe it helps you further:

`

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

plugins: [
require('karma-jasmine'),
require('karma-chrome-launcher'),

require('angular-cli/plugins/karma'),
require("karma-spec-reporter")
],

{pattern: './src/test.ts', watched: false}
],
preprocessors: {
'./src/test.ts': ['angular-cli']
},

},

},
