ERROR: cannot launch node of type [arbotix_python/arbotix_driver]: arbotix_python
ROS path [0]=/opt/ros/kinetic/share/ros
ROS path [1]=/home/yangyao/catkin_rrt/src
ROS path [2]=/opt/ros/kinetic/share

solution:

未安装 arbotix_python，找不到节点arbotix_python

sudo apt-get install ros-kinetic-arbotix

xacro: Traditional processing is deprecated. Switch to --inorder processing!
To check for compatibility of your document, use option --check-order.
For more infos, see http://wiki.ros.org/xacro#Processing_Order
xacro.py is deprecated; please use xacro instead

solution:

笔者是从indigo 上面拷贝到kinetic上出现这个问题，估计是版本的原因

  <arg name="urdf_file" default="$(find xacro)/xacro.py  '$(find rbx1_description)/urdf/litterg_2.urdf.xacro'" />

  <arg name="urdf_file" default="$(find xacro)/xacro --inorder '$(find rbx1_description)/urdf/litterg_2.urdf.xacro'" />

先安装先面的包

sudo apt-get install libproj-dev

然后找到在那个包下面出现这个问题，笔者这个是在/costmap_2d下面出来，就在其cmakelists.txt最后添加如下命令

list (REMOVE_ITEM PCL_LIBRARIES "vtkproj4")

6、

Make sure that you have installed "catkin_pkg", it is up to date and on the PYTHONPATH.

这个问题是本人在安装anaconda是遇到ros和anconda，不兼容。使用下面命令即可解决

pip install -U rosinstall msgpack empy defusedxml netifaces

备注

使用上面的命令可能遇到如下问题

Could not install packages due to an EnvironmentError: [Errno 13] Permission denied: '/home/yangyao/anaconda3/lib/python3.7/site-packages/vcstools-0.1.40.dist-info'
Consider using the `--user` option or check the permissions.

You are using pip version 10.0.1, however version 19.1.1 is available.
You should consider upgrading via the 'pip install --upgrade pip' command.

安装依赖（如果依赖可以安装无需升级pip）

pip install --user -U rosinstall msgpack empy defusedxml netifaces （在install 后面添加--user）

升级pip

pip install --user --upgrade pip 不成功的话在（在install 后面添加--user）

在安装依赖

pip install --user -U rosinstall msgpack empy defusedxml netifaces （在install 后面添加--user）

7、在本人在ubuntu16.04上装qt不能输入中文，在这里记录一下

先安装 sudo apt-get install fcitx-frontend-qt5

在复制库文件 sudo cp /usr/lib/x86_64-linux-gnu/qt5/plugins/platforminputcontexts/libfcitxplatforminputcontextplugin.so

 /home/yangyao/QtCreator/latest/lib/Qt/plugins/platforminputcontexts
将usr下面libfcitxplatforminputcontextplugin.so复制到qt安装的目录下

8、error: invalid new-expression of abstract class type  return new C;

本人在使用插件的时候遇到这个问题，这个是因为我们自己写的插件是派生类，都是继承nav::core，所示在要提前实例化里面的函数

9、The program 'roscore' is currently not installed. You can install it by typing:
sudo apt install python-roslaunch

先进行 source /opt/ros/kinetic/setup.bash

10、Ubuntu18.04网络图标不见了，解决办法

1、删除NetworkManager缓存文件
service NetworkManager stop
sudo rm /var/lib/NetworkManager/NetworkManager.state
service NetworkManager start

2、修改/etc/NetworkManager/NetworkManager.conf
managed=true

3、重启NetworkManager
sudo service network-manager restart
11 调试导航包的问题出现如下问题

1）None of the 0 first of 0 (0) points of the global plan were in the local costmap and free

2）Off Map -9.558478, 0.298699

解决方式：forward_point_distance_设置成合适的大小

12、  Could NOT find SDL_image (missing: SDL_IMAGE_LIBRARIES   SDL_IMAGE_INCLUDE_DIRS)

解决方式 sudo apt-get install libsdl-image1.2-dev

13、 Found unsuitable Qt version "" from NOTFOUND, this code requires Qt 4.x

解决方式 sudo apt-get install qt4-default

14、问题描述:程序可以编译完成，但是运行的时候遇到这个问题symbol lookup error: /home/e64/qt_project/ucar_project_motion/devel/lib//libastar_planner.so: undefined symbol: _ZN7distmap16DistanceMapClassC1Ev

解决方式:忘记在catkin_package中添加所编译的包
