ros2创建接口功能报编接口报错

我在学习ros2，跟章节走到入门篇7.3.3（ROS2接口）的时候执行colcon build --packages-select example_ros2_interfaces出现了酱紫的error，搞了半天搞不定了，也没有大佬可以帮帮我
代码以及改的和教程里面的一模一样了，然后文件是在外接的硬盘里面，是在我的电脑上面运行。

当你在使用ROS 2并尝试构建包含自定义接口的包时遇到错误，可能有几个原因。以下是一些常见的问题和解决方案，你可以尝试按照这些步骤来诊断并解决问题：

检查CMakeLists.txt和package.xml文件：
- 确保CMakeLists.txt文件中正确设置了你的接口（如.msg或.srv文件）的生成和安装。
- 在package.xml中，确保你声明了对rosidl_generate_interfaces的依赖，以及任何其他你的接口可能需要的依赖。
检查路径问题：
- 由于你的项目位于外接硬盘上，可能存在权限问题或路径过长导致的问题。尝试将项目移动到系统内部的一个较短路径下，然后再次构建。
- 确保你的ROS 2环境变量（如COLCON_PREFIX_PATH和ROS_PACKAGE_PATH）包含了外接硬盘的路径。
查看具体的错误信息：
- 错误信息通常会给出导致构建失败的具体原因。检查colcon build命令输出的最后一部分，找到具体的错误或警告信息。
- 如果错误信息指向某个具体的文件或配置问题，请仔细检查相关文件。
依赖问题：
- 确保所有必要的ROS 2包都已正确安装。你可以使用sudo apt update和sudo apt install ros-<distro>-<package-name>来安装缺失的包。
- 如果你正在使用的工作空间（workspace）依赖于其他工作空间中的包，请确保这些工作空间已被正确设置，并且它们的路径已添加到ROS_PACKAGE_PATH中。
清理和重新构建：
- 在进行任何更改后，尝试先清理旧的构建文件，然后再重新构建。你可以使用colcon build --packages-select example_ros2_interfaces --cmake-args -DCMAKE_BUILD_TYPE=Debug -DCMAKE_VERBOSE_MAKEFILE=ON（添加--cmake-args -DCMAKE_VERBOSE_MAKEFILE=ON以获取更详细的构建信息）来重新构建。
- 如果仍然无法解决问题，你可以尝试删除整个build和install目录（如果它们存在的话），然后再次运行colcon build。
查看ROS 2社区和文档：
- 如果上述步骤都不能解决问题，查看ROS 2的官方文档或社区论坛（如ROS Answers, Reddit的r/ros等）可能会有帮助。
- 搜索你遇到的特定错误或问题，看看是否有其他人遇到过并找到了解决方案。

希望这些步骤能帮助你解决问题！如果问题依然存在，请提供更详细的错误信息，以便进一步分析。

@3505337350 如果是学习ROS2，请换到最新的教程和书籍：https://www.bilibili.com/video/BV1GW42197Ck/ 上来，之前的动手学ROS2相关教程停止答疑，经历有限，只能维护一份，还请理解。
