我使用phantomjs 2.1.1和mocha进行功能测试，前端写入角度为1.6.5。
当我执行page.open()时，我收到此错误：
Error: [$injector:modulerr] Failed to instantiate module app due to:
[$injector:nomod] Module 'app' is not available! You either misspelled the
module name or forgot to load it. If registering a module ensure that you
specify the dependencies as the second argument.
