（1）$ mkdir -p ~/catkin_ws/src
（2）$ cd ~/catkin_ws/src
（3）$ catkin_init_workspace
（4）$ cd ~/catkin_ws/
（5）$ catkin_make
然而这一步出现了错误：
ImportError: "from catkin_pkg.package import parse_package" failed: No module named 'catkin_pkg'
Make sure that you have installed "catkin_pkg", it is up to date and on the PYTHONPATH.

这是由于python版本与catkin以来版本不一致导致：
可以看到两者是不一样的，所以我们要安装正确的版本：
$ conda install setuptools
$ pip install -U rosdep rosinstall_generator wstool
然后再执行（5）$ catkin_make 就成功了
（6）此时我们还要将对应的工作空间路径添加到环境变量中去
$ source devel/setup.bash
查看环境变量，$ echo $ROS_PACKAGE_PATH
若出现/home/用户名/工作空间名/src:/opt/ros/kinetic/share 则成功
