Step1: Find the path where your cv2.so is installed (if you use the python-cv wheel to install the opencv)

Step2: Export the path to your .bashrc or .zshrc file, just like this:

예시

export PYTHONPATH=”/home/userx/anaconda3/lib/python3.5/site-package‌​s:$PYTHONPATH”

进入代码目录并编译

记得source一下

cd simulation_structure/

source /opt/ros/kinetic/setup.bash

catkin_make

有错误

详情如下：

CMake Error at /opt/ros/kinetic/share/catkin/cmake/catkin_package.cmake:302 (message):   catkin_package() include dir ‘include’ does not exist relative to   ‘/home/dyz/simulation_structure/src/sensor_cmd_communication’ Call Stack (most recent call first):   /opt/ros/kinetic/share/catkin/cmake/catkin_package.cmake:102 (_catkin_package)   sensor_cmd_communication/CMakeLists.txt:108 (catkin_package)

cd src/

– Configuring incomplete, errors occurred! See also “/home/dyz/simulation_structure/build/CMakeFiles/CMakeOutput.log”. See also “/home/dyz/simulation_structure/build/CMakeFiles/CMakeError.log”. Invoking “cmake” failed

解决办法，删除sensor_cmd_communication文件夹，进入src并重新creat：

rm -rf src/sensor_cmd_communication/

cd src/

catkin_create_pkg sensor_cmd_communication rospy roscpp

详情如下：

dyz@dyz-X550CC:~/simulation_structurerm−rfsensorcmdcommunication/dyz@dyz−X550CC: /simulationstructurerm−rfsensorcmdcommunication/dyz@dyz−X550CC: /simulationstructure cd src/ dyz@dyz-X550CC:~/simulation_structure/src$ catkin_create_pkg sensor_cmd_communication rospy roscpp Created file sensor_cmd_communication/CMakeLists.txt Created file sensor_cmd_communication/package.xml Created folder sensor_cmd_communication/include/sensor_cmd_communication Created folder sensor_cmd_communication/src Successfully created files in /home/dyz/simulation_structure/src/sensor_cmd_communication. Please adjust the values in package.xml.

退出src并编译

cd ..

catkin_make

详情如下：

dyz@dyz-X550CC:~/simulation_structure/srccd..dyz@dyz−X550CC: /simulationstructurecd..dyz@dyz−X550CC: /simulationstructure catkin_make Base path: /home/dyz/simulation_structure Source space: /home/dyz/simulation_structure/src Build space: /home/dyz/simulation_structure/build Devel space: /home/dyz/simulation_structure/devel Install space: /home/dyz/simulation_structure/install
