Jasmine testjs installer fails on "pending" | 'undefined' is not a function (evaluating "expect (true) .toBe (true)")

I have a simple spec:

describe("A suite", function() {
  it("contains spec with an expectation", function() {
    expect(true).toBe(true);
  });
});

      

        
        
        
      

    

And when I run grunt jasmine

I get:

Running "jasmine:src" (jasmine) task
Testing jasmine specs via PhantomJS

 A suite
   × contains spec with an expectation
     TypeError: 'undefined' is not a function (evaluating 'expect(true).toBe(tru
e)') in file:///C:/Users/long-path-to-spec/testing-spec.js (line 4) (1)


1 spec in 0s.

The spec seems to be working ... it seems to know what "describe" and "this" are, but doesn't seem to know "expect"?

Any ideas?
