"socket.error: [Errno 98] Address already in use" in heterogeneous example on veins-lte

Question

我正在尝试更改 veins-lte "heterogeneous" 示例中的应用程序类型，但我收到以下错误（在 SUMO 日志中）：

"socket.error: [Errno 98] Address already in use"

我尝试在 SUMO 中使用不同的流量配置或使用不同的应用程序，但我总是遇到相同的错误。我能够运行这个例子，但它会在几秒钟后停止，而不会在 OMNeT++ 上显示任何错误。

这是我的 omnetpp.ini:

非常感谢任何帮助，我真的不知道如何解决...提前致谢！

I get the following error (in the SUMO log):

"socket.error: [Errno 98] Address already in use"

如果我没记错的话，这是来自Python的错误信息。这不是 OMNeT++ 错误，也不是 SUMO 会输出的错误消息。

我的猜测是您在尝试运行 sumo-launchd.py 时收到错误消息，该脚本在 OMNeT++ 需要时启动 SUMO。

我认为有两个可能的原因：

您正在尝试运行两个 sumo-launchd.py 并行实例。这是没有必要的。只有一个实例运行ning 就足够了。
一些其他程序正在使用相同的地址和端口（TCP 端口 9999）。与您是否有意运行宁此程序或 if it is malware, either shutting down the conflicting program or changing the sumo-launchd.py port number will help. See the sumo-launchd.py documentation 如何更改其端口号无关。
