树莓派（ubtuntu18.04+ros melodic）安装rosserial

试过sudo apt的方式安装失败，故本文使用下载功能包的方式安装rosserial_python,亲测有效

1.进入工作空间

cd ~/catkin_ws/src

2.从github中下载功能包

git clone https://github.com/ros-drivers/rosserial.git -b melodic-devel

3.编译

cd ..
catkin_make
catkin_make install
source ~/catkin_ws/install/setup.bash
cd ~/catkin_ws/install/share/rosserial_arduino
rosrun rosserial_arduino make_libraries.py .
