使用命令 cocos jscompile -s frameworks/js-bindings/bindings/script -c -d target 编译cocos自带的js文件，直接报如下错误
frameworks/js-bindings/bindings/script/3d/jsb_cocos2d_3d.js:43: ERROR - Parse error. Internet Explorer has a non-standard intepretation of trailing commas. Arrays w$
};

没有 -c 参数，可以编译出很多jsc文件。我现在想编译一个大文件，就报了如上的错误。看了一下python文件，似乎是compiler.jar有问题，无法把js文件合在一起。有人有解决办法吗？
