spm test 不能使用

[afc163]

版本：3.3

运行 spm test 后只有：

  Starting service for test runner ...

解决了上面的问题，但发现了另一个问题。运行覆盖率检查时，serve-spm 出错了，非常诡异。

     middleware: Serve SPM /tests/now-spec.js
     middleware: Serve SPM /expect/0.3.1/index.js
     middleware: Serve SPM /index.js
     middleware: Serve SPM /moment/2.6.0/moment.js
     middleware: Serve SPM /src/now.js
     middleware: Serve SPM /jquery/1.8.3/jquery.js


  now
    ✓ should be a string 
    ✓ should be a valid date string 


  2 passing (9ms)

            200: /tests/runner.html?cov
     middleware: Serve SPM /static/css/mocha.css

这部分代码导致的，考虑直接切换到 istanbul 或 node-jscover 了。

早先想升级 jscoverage 来着，也是遇到奇怪的问题，就没升上去。
