这是karma.conf.js文件.

执行“karma：unitTestDev”命令时,会出现以下错误.

我们在Windows和Linux OS中遇到了上述问题.在Mac中,业力成功地在PhantomJS上执行测试.

在Windows中,如果我们在Chrome浏览器中执行上述测试,而不是PhantomJS,那么karma会成功执行所有单元测试.

以下是Package.json中与业力相关的依赖关系

"phantomjs": "~1.9.7-3","karma": "~0.12.3","karma-chrome-launcher": "~0.1.3","karma-jasmine": "~0.1.5","karma-html-reporter": "~0.2.3","karma-junit-reporter": "~0.2.1","grunt-karma": "~0.8.2","karma-phantomjs-launcher": "~0.1.3"

让我知道是否有与PhantomJS的业力或咕噜声有任何已知问题.
