【CANN202306】source ~/.bashrc -bash: /opt/ros/eloquent/setup.bash: No such file or directory

source ~/.bashrc

卸载重装

sudo apt remove ros-foxy-* && sudo apt autoremove
apt install ros-eloquent-desktop

这下子终于恢复了我们应有的文件。

ros2 run demo_nodes_cpp talker

然后catkin_make平替colcon build

CMake Error at CMakeLists.txt:6 (find_package):
  By not providing "Findcatkin.cmake" in CMAKE_MODULE_PATH this project has
  asked CMake to find a package configuration file provided by "catkin", but
  CMake did not find one.

  Could not find a package configuration file provided by "catkin" with any
  of the following names:

    catkinConfig.cmake
    catkin-config.cmake

  Add the installation prefix of "catkin" to CMAKE_PREFIX_PATH or set
  "catkin_DIR" to a directory containing one of the above files.  If "catkin"
  provides a separate development package or SDK, be sure it has been
  installed.

我们来针对一下这个错误。实际上我们已经安装了colcon，不需要catkin

貌似可以安全忽略
