如何修复 Ubuntu 上的 ROS2 错误 hardware_interfaceConfig.cmake

English Deutsch 简体中文

问题

尝试使用 colcon build 构建某些 ROS 包时，你看到如下错误消息

cmake_error_hardware_interface.txt
CMake Error at CMakeLists.txt:20 (find_package):
  By not providing "Findhardware_interface.cmake" in CMAKE_MODULE_PATH this
  project has asked CMake to find a package configuration file provided by
  "hardware_interface", but CMake did not find one.

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

    hardware_interfaceConfig.cmake
    hardware_interface-config.cmake

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

解决方案

安装 ros-<distro>-hardware-interface 包。例如，对于 ROS2 Jazzy，运行

install_hardware_interface.sh
sudo apt install ros-jazzy-hardware-interface
