在Ubuntu上安装Colcon

Question

感谢任何帮助:我只是想在一个运行ubuntu的虚拟机上安装Colcon --我正在使用这个命令：colcon build --symlink-install我得到了这个错误：

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

您似乎没有安装某些环境变量。

当我尝试用Colcon构建ROS2项目时，我也遇到了类似的问题。但是，当我最初开发我的环境时(像. ~ros2_ws/install/setup.bash)这样的东西)，它变得很好。

附注:如果在您的案例中这个问题也与ROS有关，那么不要忘记在构建后将已安装的库添加到类路径中：. install/setup.bash。
