Crossbar说'没有callee注册程序'

Question

尽管有两个节点连接到我本地网络上的交叉开关路由器，但他们没有看到对方，浏览器控制台正在说：

浏览器控制台

Potentially unhandled rejection [1] {"error":"wamp.error.no_such_procedure","args":["no callee registered for procedure <com.at.mcu.e6a003528063>"],"kwargs":{}} (WARNING: non-Error used)

Crossbar版本：

Crossbar.io      : 17.11.1 (Crossbar.io COMMUNITY)
Autobahn         : 17.10.1 (with JSON, MessagePack, CBOR, UBJSON)
Twisted          : 17.9.0-EPollReactor
LMDB             : 0.93/lmdb-0.9.18
Python           : 2.7.13/CPython
OS               : Linux-4.4.91-ti-r133-armv7l-with-debian-9.2
Machine          : armv7l

从纵横开始的日志 - 您可以看到后端python脚本和浏览器已加入底部：

我有：

• 确认两者都试图加入相同的URI： com.at.mcu.e6a003528063 。
• 发现相同的浏览器和python代码在放置在另一台机器上时正确连接（BeagleBone Black Wireless运行稍微不同的Debian版本）。 出于这个原因，我认为它与crossbar的安装和/或配置有关。
• 在工作机器（它工作）和非工作机器（不工作）的新virtualenv从头开始重新创建横梁。
• 确认.crossbar / config.json是相同的。
