No rule to make target /usr/include/eigen3/Eigen/src/Core/../Plugins/CommonCwiseUnaryOps.h', needed by block_grasp_generator-hydro-devel/CMakeFiles/block_grasp_generator_visualization_tools.dir/src/visualization_tools.cpp.o'. Stop.

the file "CommonCwiseUnaryOps.h" exists in "/usr/include/eigen3/Eigen/src/plugins"

eigen_conversionsConfig-version.cmake is in /opt/ros/hydro/share/eigen_conversions/cmake

eigen_conversionsConfig.cmake is in /opt/ros/hydro/share/eigen_conversions/cmake

我应该怎么办？

另一个问题是路径是什么"/usr/include/eigen3/Eigen/src/Core/../Plugins/"意思，两个点意味着什么？

2个点的意思是go to the parent directory，所以

/usr/include/eigen3/Eigen/src/Core/../Plugins/

意味着去

/usr/include/eigen3/Eigen/src/Plugins/

请注意，它Plugins是大写的，而您的文件是plugins小写的

/usr/include/eigen3/Eigen/src/plugins
