在macroros教程中《控制OLED-自定义消息接口》无法编译

ELLAW

环境是ubuntu22，用的是小鱼脚本安装的ros2 humble

教程章节：
https://fishros.com/d2lros2/#/humble/chapt14/advance/1.控制OLED-自定义消息接口

进行到该章节第2.2 编译功能包时，
colcon build后，提示~

Starting >>> fishbot_interfaces
--- stderr: fishbot_interfaces                         
CMake Error at /opt/ros/humble/share/rosidl_cmake/cmake/rosidl_generate_interfaces.cmake:229 (message):
  Packages installing interfaces must include
  '<member_of_group>rosidl_interface_packages</member_of_group>' in their
  package.xml
Call Stack (most recent call first):
  CMakeLists.txt:29 (rosidl_generate_interfaces)

Failed   <<< fishbot_interfaces [3.01s, exited with code 1]
                                
Summary: 0 packages finished [3.20s]
  1 package failed: fishbot_interfaces
  1 package had stderr output: fishbot_interfaces

安照错误提示，在package.xml中加上 <member_of_group>rosidl_interface_packages</member_of_group>后可以通过编译。

继续后按照教程，编译时提示错误

--- stderr: fishbot_interfaces
CMake Error at CMakeLists.txt:27 (find_package):
  By not providing "Findrosidl_default_generators.cmake" in CMAKE_MODULE_PATH
  this project has asked CMake to find a package configuration file provided
  by "rosidl_default_generators", but CMake did not find one.

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

    rosidl_default_generatorsConfig.cmake
    rosidl_default_generators-config.cmake

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