Robe JS无法在我的节点上运行

从教程… app.js —>

"use strict" var som = require('robe'); var xxx = yield som.connect('localhost'); 

---

执行节点–harmony app.js

 $ node --harmony app.js /Users/admin/project/test/app.js:6 var xxx = yield som.connect('localhost'); ^^^^^ SyntaxError: Unexpected strict mode reserved word at exports.runInThisContext (vm.js:69:16) at Module._compile (module.js:432:25) at Object.Module._extensions..js (module.js:467:10) at Module.load (module.js:349:32) at Function.Module._load (module.js:305:12) at Function.Module.runMain (module.js:490:10) at startup (node.js:124:16) at node.js:807:3 

它会不是意想不到的“收益”或“类”节点版本0.11.15谁知道发生什么事情或解决scheme？
