Heroku support

你好，我已在heroku成功部署node版，在windows上使用正常，但是在openwrt上运行报错，报错信息如下：
shadowsocks-dotcloud v0.9.6
7 Jun 22:25:15 - server listening at port 8800
7 Jun 22:26:02 - local connected
connections property is deprecated. Use getConnections() method
7 Jun 22:26:02 - concurrent connections: 1

crypto.js:250
  this._binding = new binding.Cipher;
                             ^
TypeError: Cannot read property 'Cipher' of undefined
    at new Cipher (crypto.js:250:30)
    at Object.Cipher (crypto.js:249:12)
    at new Encryptor (/etc/shadowsocks-heroku/encrypt.js:65:30)
    at Server.<anonymous> (/etc/shadowsocks-heroku/local.js:76:17)
    at Server.EventEmitter.emit (events.js:95:17)
    at TCP.onconnection (net.js:1180:8)
能看一下是什么原因吗?
