catkin与python的兼容问题

CMake Error at /opt/ros/kinetic/share/catkin/cmake/safe_execute_process.cmake:11 (message):

  "/opt/ros/kinetic/share/catkin/cmake/parse_package_xml.py"

  CMakeLists.txt:52 (find_package)

　　在catkin_make的时候发生这种错，和明显和anaconda发生了冲突，anaconda将默认的pyhon版本改变了，导致了catkin_make发生了错误。

解决方法

   检查一下Python的版本： ~$ python -V
  检查一下catkin依赖的Python版本： ~$ dpkg -L python-catkin-pkg
如果Python的版本和catkin依赖的版本不一样，说明Python依赖包有问题，解决办法：

conda install setuptools  
  
pip install -U rosdep rosinstall_generator wstool rosinstall six vcstools
