系统：ubuntu24.04
ROS2：Jazzy（鱼香ros一键安装）
问题：colcon build 时报错：
CMake Error at CMakeLists.txt:12 (find_package):
By not providing "Findbase_interfaces_demo.cmake" in CMAKE_MODULE_PATH this
project has asked CMake to find a package configuration file provided by
"base_interfaces_demo", but CMake did not find one.
Could not find a package configuration file provided by
"base_interfaces_demo" with any of the following names:
base_interfaces_demoConfig.cmake
base_interfaces_demo-config.cmake
Add the installation prefix of "base_interfaces_demo" to CMAKE_PREFIX_PATH
or set "base_interfaces_demo_DIR" to a directory containing one of the
above files. If "base_interfaces_demo" provides a separate development
package or SDK, be sure it has been installed.
失败尝试：
- 尝试更新列表
sudo apt update然后安装sudo apt install base_interfaces_demo（无法定位软件包）
最终解决办法：
-
find / -name "base_interfaces_demo" 2>/dev/null
找到所有相关文件，在我的系统里找到这个包在：/home/lihaoting/.local/share/Trash/files/install/**目录下有
-
打开.bashrc文件（一般是隐藏的，在家目录下ctrl + h 就能显示）
-
在末尾添加
export CMAKE_PREFIX_PATH=/home/lihaoting/.local/share/Trash/files/install:$CMAKE_PREFIX_PATH并保存退出 -
重新编译即可
