Not able to run mocha tests with blanket - CH11

I'm at the portion of your book where I'm running the code-coverage test with blanket and I am having the following error being thrown:

C:\meanstack>npm test

> socialapp@ test C:\meanstack
> jshint . && mocha && protractor

C:\meanstack\controllers\api\users.js:2
if (typeof _$jscoverage['C:\meanstack\controllers\api\users.js'] === 'undefine
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
Error: BLANKET-Error parsing instrumented code: Error: BLANKET-Error parsing instrumented code: Error: BLANKET-Error parsing instrumented code: SyntaxError: Unexpected token ILLEGAL

I cannot figure out where the issue is so I can run this test.
