Failed micro_ros_agent [1.83s, exited with code 2]解决方案
经过摸索在执行 ros2 run micro_ros_setup build_agent.sh 命令之前从源码编译安装一个 6.x 版本的 fmt 库即可具体步骤如下
如果已经遇到该错误可以先清除 micro_ros_agent 的编译安装缓存
cd ~/microros_ws
rm -r build/micro_ros_agent
rm -r install/micro_ros_agent从源码编译安装 fmt-6.x我在 ubuntu-20 系统上编译安装的是 fmt-6.1.2
wget https://github.com/fmtlib/fmt/archive/refs/tags/6.1.2.zip
unzip 6.1.2.zip
cd fmt-6.1.2
mkdir build cd build cmake .. make -j4
sudo make install继续编译 micro_ros_agent
ros2 run micro_ros_setup build_agent.sh
source install/local_setup.bash参考链接
Microros 官方编译安装文档 https://micro.ros.org/docs/tutorials/core/first_application_linux/
build_agent.sh fails while trying to go through tutorial https://github.com/micro-ROS/micro-ROS-Agent/issues/50
