Karma + jspm + PhantomJS "Could not load PhantomJS" - unit-testing

Question

I'm running an Aurelia project on Windows, and I want to run Karma with PhantomJS. I also have JSPM and Babel similarly in the skeleton project here.
[karma]: No captured browser, open http://localhost:9876/
[karma]: Karma v0.13.22 server started at http://localhost:9876/
[launcher]: Can not load "PhantomJS"!
RangeError: Maximum call stack size exceeded

Here is my karma.conf.js:
module.exports = function(config) {
config.set({
basePath: '',
frameworks: ['jspm', 'jasmine'],
plugins: [
'karma-babel-preprocessor',
'karma-jspm',
'karma-jasmine',
'karma-phantomjs-launcher'
],
jspm: {
loadFiles: ['src/**/*.js', 'test/**/*.js'],
serveFiles: ['src/**/*.js'],
paths: {
'*': '*',
'github:*': 'jspm_packages/github/*',
'npm:*': 'jspm_packages/npm/*'
}
},
preprocessors: {
'test/**/*.js': ['babel'],
'src/**/*.js': ['babel']
},
'babelPreprocessor': {
options: {
sourceMap: 'inline',
moduleIds: false,
optional: [
'es7.decorators',
'es7.classProperties'
]
}
},
defaultJSExtensions: true,
reporters: ['progress'],
port: 9876,
colors: true,
logLevel: config.LOG_INFO,
autoWatch: true,
proxies : {
'/src/': '/base/src/',
'/jspm/': '/base/jspm/'
},
browsers: ['PhantomJS'],
customLaunchers: {
'PhantomJS': {
base: 'PhantomJS',
options: {
settings: {
webSecurityEnabled: false
},
},
flags: ['--load-images=true'],
// debug: true
}
},
phantomjsLauncher: {
exitOnResourceError: true
},
singleRun: false
});
};
Here is my gulp file:
var gulp = require('gulp');
var Karma = require('karma').Server;
/**
* Run test once and exit
*/
var karmaConf = __dirname + '/../../karma.conf.js';
gulp.task('test', function(done) {
new Karma({
configFile: karmaConf,
singleRun: false
}, done).start();
});
/**
* Watch for file changes and re-run tests on each change
*/
gulp.task('tdd', function(done) {
new Karma({
configFile: karmaConf
}, done).start();
});
/**
* Run test once with code coverage and exit
*/
gulp.task('cover', function(done) {
new Karma({
configFile: karmaConf,
singleRun: true,
reporters: ['coverage'],
preprocessors: {
'test/**/*.js': ['babel'],
'src/**/*.js': ['babel', 'coverage']
},
coverageReporter: {
includeAllSources: true,
instrumenters: {
isparta: require('isparta')
},
instrumenter: {
'src/**/*.js': 'isparta'
},
reporters: [
{ type: 'html', dir: 'coverage' },
{ type: 'text' }
]
}
}, done).start();
});
My versions:
JSPM: 0.16.15
NPM: 3.8.3
Gulp: 3.9.1
Karma: 0.13.22
I do have my PhantomJS path set (running >phanthomjs works).
