Crossbar.io - WAMP 라우터가 작동하지 않습니다.

Question

이 지시를 따르고 localhost:8080을 통해 프론트 엔드에 액세스 할 수 있지만 백엔드 쪽에서 hello.js가 실행되지 않은 것처럼 보입니다.

Answer 1

Crossbar.io에서 NodeJS 실행 파일을 찾을 수 없습니다. config.json에 정규화 된 경로가 필요합니다.

예. 우분투에, NodeJS가 /usr/bin/nodejs에 설치되며, 기본적으로 생성 된 Crossbar.io 노드 구성으로 그 일을하기 위해, 당신은 할 필요가 :

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

그래서 당신이

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 
-rwxr-xr-x 1 root root 1462424 Mär 27 2014 /usr/bin/nodejs
