Colcon构建故障:“找不到“ Ament_cmake”提供的软件包配置文件

Question

任何帮助：我只是想在运行Ubuntu-和的虚拟机上安装Colcon和我正在使用此命令：colcon build --symlink-install 我遇到了这个错误：

Starting >>> sick_scan2
--- stderr: sick_scan2
CMake Error at CMakeLists.txt:24 (find_package):
By not providing "Findament_cmake.cmake" in CMAKE_MODULE_PATH this 
project
has asked CMake to find a package configuration file provided by
"ament_cmake", but CMake did not find one.
 Could not find a package configuration file provided by "ament_cmake" 
with
any of the following names:
ament_cmakeConfig.cmake
ament_cmake-config.cmake
Add the installation prefix of "ament_cmake" to CMAKE_PREFIX_PATH or set
"ament_cmake_DIR" to a directory containing one of the above files.  If
"ament_cmake" provides a separate development package or SDK, be sure it
has been installed.

Answer 1

看来您没有安装某些环境变量。

当我尝试使用COLCON构建ROS2项目时，我也有类似的问题。但是，当我最初采购环境时(类似. ~ros2_ws/install/setup.bash)，它就可以了。

P.S。如果您的情况也是关于ROS的问题，请不要忘记在构建后将安装的库添加到Class Path：. install/setup.bash。

Answer 2

我目前正在从事一个ROS2项目，并且收到了与您收到的相同错误消息。当我进入工作空间并从Foxy文档中输入命令source /opt/ros/foxy/setup.bash时，https://docs.ros.org/en/foxy/foxy/installation/ubuntu-inbuntu-install-debians.html#envorirnment-setup and and ant ant。希望这会有所帮助！
