Unit testing 如何调试Karma runner vs PhantomJS浏览器的启动？

我在使用Karma runner+PhantomJS浏览器运行单元测试时遇到问题

Karma服务器启动，然后PhantomJS浏览器启动，然后什么也没发生。一分钟后，我得到了一个信息，60年代没有任何东西被捕获，杀戮过程

[11:08:35][Step 3/5] Running "karma:allTests" (karma) task

操作系统是redhat6。

不同版本的karma phantomjs启动器和phantomjs预构建存在一些不兼容问题

尝试降级您的phantomjs预构建版本
