ubuntu - colcon 构建失败 : 'Could not find a package configuration file provided by "ament_cmake"'

Question

任何帮助表示赞赏:
我只是想在运行 ubuntu 的虚拟机上安装 Colcon-和
我正在使用这个命令:colcon build --symlink-install
我收到此错误:

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

看来你没有安装一些环境变量。

当我尝试使用 Colcon 构建 ROS2 项目时，我遇到了类似的问题。
但是，当我最初采购我的环境时(类似于 . ~ros2_ws/install/setup.bash))，它变得很好。

附言如果您的问题也与 ROS 有关，请不要忘记在构建后将已安装的库添加到类路径:. install/setup.bash .
