Crossbar.io - WAMP路由器不工作

Question

我按照這個指令http://crossbar.io/docs/Getting-started-with-NodeJS/，我可以通過localhost:8080訪問前端，但似乎在後端沒有執行hello.js。這是日誌我運行後crossbar start：

話雖然前端不斷髮布對通道「onhello」，但服務器尚未收到並記錄任何東西。什麼是錯誤，誰能幫我解決這個問題？謝謝。

Crossbar.io無法找到NodeJS可執行文件。它需要config.json中的完全合格路徑。

E.g.在Ubuntu上，是的NodeJS下/usr/bin/nodejs安裝，並且使這項工作在默認情況下產生的Crossbar.io節點配置，你需要做的：

sudo ln -s /usr/bin/nodejs /usr/bin/node 

等你拿

oberstet@ubuntu1404:~/temp/node4$ ls -la /usr/bin/node 
lrwxrwxrwx 1 root root 15 Okt 31 09:35 /usr/bin/node -> /usr/bin/nodejs 
oberstet@ubuntu1404:~/temp/node4$ ls -la /usr/bin/nodejs
