使用cmd打包ext的时候报了一个诡异的错误。

细细找来，发现是代码书写导致。如今记录一下：

错误具体信息：

[ERR] C2009: YUI Parse Error (identifier is a reserved word =>
debugger;) -- unknown-file:198775:12
[ERR] C2009: YUI Parse Error (Compilation produced 1 syntax errors. => null) --

看错误第一行就能够看出是解析 debugger的时候出错的，看我的代码，发现我调试的时候debugger写入了没有去掉，打包的时候就出现了这个错误，将debugger去掉。再又一次打包。发现，程序正常打包。
