波纹模拟器无法在Max OSX上运行

当为我的Phonegap项目启动我的波纹模拟器时，我遇到了问题。当我在常规开发文件夹（而不是平台子文件夹）中启动Ripple-Emulate命令时，波纹仿真器启动，但显示错误消息：

Error: static() root path required
at Function.static (/usr/local/lib/node_modules/ripple-emulator/node_modules/express/node_modules/connect/lib/middleware/static.js:49:20)

at pass (/usr/local/lib/node_modules/ripple-emulator/node_modules/express/lib/router/index.js:107:24)

Chrome指出了这一点：无法加载资源：服务器的响应状态为500（内部服务器错误）（无法加载config.xml文件），尽管我的www文件夹中有config.xml文件。

当我启动涟漪仿真--path platform / ios / assets / www时，也无法解决此问题，然后显示：无法GET /错误（再次抱怨config.xml文件）。

有人知道解决方案吗？
