Why is not recognizing jQuery object

[wellyal]

I did everything was said, but I don know why I can't make it work.

{
  "spec_dir": "spec",
  "spec_files": [
    "**/*[sS]pec.js"
  ],
  "helpers": [
    "helpers/**/jquery.min.js",
    "helpers/**/jasmine.js",
    "helpers/**/jasmine-jquery.js"
  ],
  "stopSpecOnExpectationFailure": false,
  "random": false
}

$ jasmine
module.js:327
    throw err;
    ^

In my setup I don't have a helpers section. Check this, and run npm install jquery --save-dev on top of that
