@因却斯丁 我这边是正常的，/opt/ros/humble/share/rosidl_cmake/cmake/rosidl_generate_interfaces.cmake:229的上下文如下（可以看到__group_name的值是rosidl_interface_packages）：
224 set(_group_name "rosidl_interface_packages")
225 if(NOT _AMENT_PACKAGE_NAME)
226 ament_package_xml()
227 endif()
228 if(NOT _group_name IN_LIST ${_AMENT_PACKAGE_NAME}_MEMBER_OF_GROUPS)
229 message(FATAL_ERROR
230 "Packages installing interfaces must include \
231 '<member_of_group>${_group_name}</member_of_group>' \
232 in their package.xml"
233 )
你这个确实有点奇怪。是不是没有执行 sudo apt upgrade 之类的导致的？
