LCM 自检失败，检查路由表和防火墙设置

Question

我有 ubuntu 20.04，我安装了 drake 并尝试了运行示例。当我尝试运行 bazel-bin/tools/drake_visualizer & bazel-bin/examples/multibody/inclined_plane_with_body/inclined_plane_with_body 时出现错误：

Answer 1

LCM 的网络配置出现问题。例如，如果没有 lo（环回）设备，或者它被禁用，或者配置奇怪。

有关提示，请参阅 https://lcm-proj.github.io/multicast_setup.html。
